No date yet sorry, I haven't even started on a draft.

@@SpeakToTheGeekTech No worries I was just being lazy. Ill figure it out as Im an IT person but no ESP32 experiance :)

There are smaller models fortunately! And all sorts of ways of placing them around a home: wall mounting is an option. I’ve even seen photos of chimneys being replaced with them up top of a roof so they’re fully out of the way!

@@SpeakToTheGeekTech i don’t have a chimney either 🤣. Heat pump videos do not shoe an average terrace house, 2 bed semi, or flat. The house shown here is far from average.

To control a relay or to directly connect the ESP module to the button terminals on the garage door opener? If the latter, I was nervous about recommending anyone directly connect the ESP to the garage door controller because you never know if some brands push voltage through them or not. I figured the volt-free contact from a relay was the safest way to do it.

... as a significant cause of respiratory diseases and related conditions, I totally agree yes!

@@SpeakToTheGeekTech Not at all, good stuff, great heat, can't beat the glow !

In terms of its accuracy, it is spot on based on the data it has. However what the tariff comparison doesn't consider is that you would probably shift your usage pattern to align with the different tariffs in real life. And comparing with Agile is always going to be dodgy... it's just far too unpredictable! Still, I do agree it's a great tool for getting a rough idea of what could have happened

@@SpeakToTheGeekTech I think there is something wrong with the tariff hopping (which is in beta) for me as the winter Flux prices are very flow given my high ASHP consumption. The tariff comparison seems correct. Regardless its much easier to use than creating a spreadsheet 👍

Ah ok. Have you checked the meter data gap tool to see if there is data missing?

I've heard rumours about some Corsas not playing well with home chargers. Personally speaking I've never had any issues charging the Corsa at home (well, not caused by the car anyway!). I've always used the charger's scheduling features though because the car's built-in scheduling function is absolute pants. I did however have frequent public charging issues with it, I reckon 50% of my public charging attempts failed with the chargers refusing to negotiate with the car whilst other car owners could use the same chargers with no issues.

In theory a bug concerning safety would be managed through a recall, either voluntary or forced as it would be now. However that recall process can be a slow turning wheel!

It has put me off Stellantis a bit to be honest. It could just be because it’s their first generation EV, maybe they’ll get the hang of it after learning lessons from it.

@@SpeakToTheGeekTech let's see how it goes with the dealer - perhaps they can redeem themselves? I wonder if they have any internal knowledge sharing between EV technicians? Do you have any kind of 12V battery voltage monitoring? I remember MrEV had something which he used to debug 12V battery issues by monitoring voltage continuously over time. Might also be interesting to see if there are any parasitic drains on 12V? Apologies if this was all ruled out early on, but there's three reasons I'm going back to this: 1. When I had my 22kwh Zoe, I had some weird intermittent errors which went away and stayed away on 12V battery replacement, or by charging the 12v battery with an external charger. The hypothesis on Zoe forums was that it was an inter module communication issue caused by low 12v battery voltage. Also, our MG ZS EV has a 12V meter on the dashboard - I guess it's there for a reason? 2. Using and analogy from SW development - we all know the most epic debugging sessions happen when we make a wrong assumption early on, which doesn't get revisited until we've ruled out all other possible options. I learned recently this is a recognised problem for pilots troubleshooting planes in the air - it's known as a "framing problem". 3. Occams Razor - the simplest cause is the most likely. Genuinely trying to help - I appreciate you are much closer to the problem and it also seems impossible the Cleverly EV team could miss something basic, however. Do you know if they managed to repro the issue with a CAN bus data recorder in place?

@@AndrewEbling Hi! Thanks for the reply... I don't have any 12V monitoring but I'm sure that would have been useful. The saga is now over though, I won't spoil the ending but part three is scheduled in for about 3 weeks time. I don't think Cleevely missed anything obvious really, from reading on the forums about other owners experiences with this error message I suspect the car throws this error by default... like the accidental else clause in its software!

@@SpeakToTheGeekTech 😅 that's great to hear - I'll look forward to the next, and hopefully final, installment! I can almost see the code: ... else { // TODO - clear the error } 🤓

I don't know sorry. It might be worth asking on GitHub in the discussion for the integration. github.com/jwillemsen/daikin_onecta

Same for me just "Something Went Wrong"

Sat nav?

Honestly, I absolutely love the Corsa to drive and it’s been brilliant until now, and I want EVs to have a brilliant reputation, but this has made me think twice about older models. I’m hoping it’s just Stellantis and their first generation teething troubles because there are many other brands out there with second hand stock and a good reputation

@@SpeakToTheGeekTech it would be useful to get more of these long term ownership reports for EVs. The myth is that EVs are unproblematic but in reality they seem to be just like other cars. Fewer parts to fail but the parts that fail are expensive. And I'm saying that as someone who will never drive an ICE car again!

Yeah that battery-disconnect trick didn't work for me sadly.

Glad it helped

My sensors are all unavailable since a couple of weeks, but I can see everything in de HA PSA addon and up2date, so the sensors are the issue, did anything change to the sensor setup in Config.yaml?

I can't give away the ending, but part 3 is scheduled for a few weeks time :)

Nothing to do with it being an EV... it's the shared 12v stuff that's broken. A petrol one could have the same issue. I've driven a petrol Corsa too, it's a terrible driving experience.

I think Vauxhall are just prone to electrical issues they are French now after all my petrol corsa broke down weekly with one electrical issue after another.

Yes, go back to petrol, and await the the failure of the wet cambelt when it's out of warranty with the potential cost of a new engine!

Not with regular AC-coupled batteries, no. Something like the GivEnergy AIO with the gateway would be able to keep your solar inverter running and allow the batteries to charge, but a normal EPS doesn't allow that. Hybrids can charge from solar during a power cut too.

@@SpeakToTheGeekTech how do you mean hybrid?

@SpeakToTheGeekTech Can you advise of a way we can get around not being able to use the solar power?

You mentioned you had AC coupled inverters. Hybrid inverters run both solar and batteries at the same time, one inverter for both, so they can charge the batteries direct from their own panels because it’s all internal.

There is no way around that during a power cut unless you have a gateway to isolate you from the grid, or a hybrid inverter that has the panels and batteries connected directly.

Usually, yes. But you can then link Home Assistant to HomeKit and share the device back again that way. That's what I do so things are controllable in both HA and HK.

@@SpeakToTheGeekTech Thanks you.

My error couldn't be cleared by resetting.

@@SpeakToTheGeekTech That's interesting, as I said in another comment on the other video I've been a mechanic, and hands on workshop manager (since 1999) for a total of nearly 40 years. Although it is trucks rather than cars, we really struggle with diagnostics, we usually do a fault code read, save a copy, and clear the faults, you'd be amazed just how many faults build up other time, yet the car/truck runs fine without any warnings. You can have stored faults, or active faults, active faults sometimes clear, if they don't then you really need to find the cause, sometimes its straightforward other times we send them to the main dealer (yes they also struggle at times) or for cars a local specialist. I really can't see that this fault on your car is a software issue, you've had the car for at least 3 years, and if the software hasn't recently been updated prior to your visit to Cleeveleys why do you now get an error? I mentioned before that we generally clear the codes, well loads of those codes are communication issues, it could be a component causing those issues, it could be faulty wiring, one thing I'm certain is it will be a nightmare to find especially if it doesn't happen very frequently (think on a test drive). I expect Vauxhalls will throw parts at it until its fixed at your expense - so insist they put in for a warranty contribution towards the repairs, they will say no at first but it can be done, especially if the car has low mileage and is only just out of warranty - they can only do this after they think they've fixed it. Apart from cost, this is the very next reason I'm driving a 15 year old car, and the wife's car is a 2007 Corsa, they are far too complicated nowadays.

@@TheRonskiman Thanks for that info, well there is a part 3 to this story coming up in a couple of weeks but I won't spoil the ending :)

@@SpeakToTheGeekTech I hope you got lucky and it was an easy (cheap) fix.

Yeah at least we have a second car as a family though, it could be so much worse.

I suspect that may partly be the case. They have to provide updates to independents and technically they are… just in an awkward and costly way.

Me neither, it should be a bug fix and they should allow owners to update their own cars if they want to.

Sounds like a law that needs to happen

Not many cars do have OTA updates for crucial components such as the ECU. Lots with OTA for infotainment, many more with manually-updatable infotainment using software downloaded to a USB stick, but very few exist that update key CANBUS connected components.

@@SpeakToTheGeekTech all the 1000s of bugs they fixed over 10 years and didn't give to anyone, hope it was perfectly secure to start with

Your MG4 should have a 7 year warranty though right? The Corsa was 3 years and they didn't even offer me an extended one which is odd - normally they are all over the upsell! I think Stellantis have taken a malicious compliance approach to the regulations.

Too early for EV adoption where I'm concerned. Fine if willing to buy new and take the forecourt hit, but once warranty going you seem to have bob and no hope option wise. Cut off access to those friendly non stealership garages. Needs another 5 years for me to be happy and let the real world data and pain playout

One of the points I was making with this video is that this isn't an EV-specific issue. This is just a car like any other, and the components that are having issues are the same components shared with the petrol and diesel counterparts. This whole vlog could have been about any car, it just so happens it's an EV. The general complexity of the electronics in all new cars is generally more than the dealers are equipped to look after.

@@SpeakToTheGeekTech I understood that, but I've read too many unsettling reviews / comments (even in this channel) to be comfortable being beholden to a manufacturers 'software fix' EV's more than most are simply code on wheels

Shouldn't the industry approach this type of intermittent fault by installing a data logger? The warning is the result of signals on the CAN bus and once the error shows and is recorded it should be possible to diagnose it. I thought the systems were designed with this in mind. Just saying.

I guess though that's why they were put up for sale by their owners, so the chances of there being an error were higher. It's a shame though, I really want EVs to have a better reputation. My Corsa was amazing for 44k miles, I just wish it had been a more mechanical breakdown rather than electrical! I almost went for a Zoe on those PCP deals, I remember them! £99 deposit and £99/month but you had to pay rent on the batteries too if I recall. We needed a bigger car at the time though which was the main deciding factor.

@@SpeakToTheGeekTech They were all first owners bought new.

Oh wow. Well, I hope yours stays working! It proper stresses me out having the deal with the back and forth of getting things like this fixed.

@@SpeakToTheGeekTech I think mine was one of the first few in the country and apart from this issue it is still a great car. What I will never know is what caused it as it had been reliable for a year or so beforehand. Waiting for part 3 to see how you get on.

Update after Auto car engineer done some investigation Climate ECU shows 51 Bar for reference system pressure, EV control unit shows correct system pressure 5 bar software update to correct above. Booked in for software update with Renault Report from Renault Checked for cause of aircon not working, Checked gas pressure all ok, Carried out Clip check on EVC computer, found EVC computer not configured to have aircon, Carried out reconfiguration of EVC computer and tested all ok

@@ecoterrorist1402 So not even a fault, a misconfiguration

That doesn't even sound like an update, it sounds like the EVC wasn't set up correctly! Hope it's all ok now though.

@@Joe-lb8qn yes a software fault, but why?

@@ecoterrorist1402 I'd say it's clearly not a fault, the ECU was wrongly configured. Very different to a software fault or needing an update. The software didn't need to be changed. Hopefully you can let Cleverly know this so if they see similar in future they can try to rule it out before expensive tests.

Yup, warranty had recently expired

They are slowly expanding their operations across the whole UK. They are only just starting to install in Wales, I was the third here I think. It’s a sensible approach I think because they don’t want to install where they haven’t got local support in place or they can’t offer the service to you that they promise.

You paste it into a text file on your computer and save as a .yaml file - the video shows the upload process. Or visit the article in the video description and there’s a button you can click to import it automatically.

@@SpeakToTheGeekTech 👏Thanks, that worked perfectly

But overall less damaging to planets

@@SpeakToTheGeekTech 👍🤣

This is quite old now and there are many changes. When I get chance I’ll do an updated video. I don’t know of any way of testing it without doing the actions live really. You’d need a battery simulator to do that!

9x 390W. I ave a GivEnergy battery (AIO and AC3). All in the other videos on my channel.

Wow, it sounds like your solution is way more advanced than mine! I have ESPAltherma but because it uses the heat pump's temperature sensors it's not considered very accurate for calculating the heat output.

The integration’s default configuration should keep you within the API limits. If you tweak it then things start going wrong! And yes, Billy and his team did a great job. I hadn’t named any of them specifically in the videos in case they wanted their privacy but they were happy with me filming everything else (I think!)

No this is very different to the ESPAltherma/Shelly approach. It monitors the status and allows basic control but it doesn’t give you real time flow data because the update interval is too slow

@@SpeakToTheGeekTech Good to know. The M5 Tough is ready and I will order Shelley once I know the outcome. Do you have plans to do a video on setting up Heat Pump Monitor?

It's on the to-do list but not near the top!

No, the app and integration use the same API

@@SpeakToTheGeekTech curses, thank you for the confirmation!

Yeah works pretty well for me so far and has survived a number of reboots and updates.

@@SpeakToTheGeekTech to this day it is a toss of a coin! Arotherm devs could do with chatting to Daikin devs...

That's not even something their controller or app exposes.

Could you explain what the helper is that calculates scop is please?

There is no ability to calculate the SCOP using this integration. It doesn't provide any heat energy out values, or enough of a refresh rate on the data to be able to calculate one.

Seems like there is something missing in the MCS standard where the SCOP is supposed to be guaranteed, yet there isn’t any way for an owner to find out the SCOP from a standard Octopus Energy heat pump installation (I know open energy monitoring does provide it, but it needs a modification to the plumbing and extra money)

There is, you look on the MMI under information > energy data. You can view the electrical energy consumed and heat energy produced. Calculate heat energy produced / electrical energy consumed and you get your COP for that period. It's just not exposed by the API.

I doubt it sorry. There are options for monitoring it locally (ESPAltherma), a potential expensive wired network add-on that I’ve heard lets your control it locally but I’ve never tried. But by default there is no local access to the heat pump

@@SpeakToTheGeekTech Ooo, thanks for this, looks like can get one for £20. When my heatpump is installed I'll give this a try

No you can’t control that via the cloud - that’s only configurable via the MMI to my knowledge. It’s normal user controls that are exposed such as internal set points, thermostat modes, and hot water boosting

Shame - would be nice to be able to automate and actually monitor heat output and electricity usage

What you're seeing in the video is me actually running through the process live. I cut out a bit of the waiting, but genuinely this video is me configuring it on a fresh(ish) installation of Home Assistant on a Raspberry Pi for the very first time. The tricky part might be around the redirect URL, and you must make sure that you have your My Home Assistant URL configured correctly in your browser cache too (my.home-assistant.io)

@@SpeakToTheGeekTech I don't know how to do this correctly. when i open this page i have linkt to my http page awailable from outside: 8123 xxxx:8123/auth/external/callback gives me: Missing state parameter

If you try and access homeassistant.local:8123 does that open your Home Assistant installation for you?

This should all be done internally on your own network, not externally accessible. Don’t use a public address for any of this

@@SpeakToTheGeekTech Yeah I havdto fuck around with this part a bit as it wasnt working but all good now

I opened it up and took a look inside :) There's a regular-looking Grundfos branded central heating pump inside the heat pump itself. Good luck with your install!

@SpeakToTheGeekTech That's great, thanks for the info. Fingers crossed that our install goes as well as yours!

Sadly not, I still have gas because of my gas hob so I'm still paying the standing charge for that.

@@SpeakToTheGeekTech Oh!

Give it a little while to refresh

It must be the same type as supplied with the thermostat
