After Modification, to which terminals will the Motor be connected ( Relay Terminals Or the Initial Output Terminals)?

Which of the Sonoff requires no Modifications?

Hi, I have an EO mini charger, I have two wires from the plug side to the car, I have used the Shelly 1, but I can turn it on but it won't shut off, it makes the clicking noise but it does not shut off, van you please advise.

can i do the sam thing with the shelly 1pm insted ?? the inled on the device are not simular !

Hi, I have a QUBEV Mk1, also made by Rolec and I'm getting my sparks to instal a Shelly relay. Is the layout much different? There's space enough but maybe the connections differ, so a little help is appreciated :) Especially as the night rate of 9p is a lot better that 32p but getting out at 00:30 to plug in manually is not appealing in winter! :)

I've used the Relay Version and it can be powered on 12v DC or 5v via the USB. I've installed it to interup the CP live to the tethered cable and picked off 12V DC off the 12 V pins on PodPoint Solo

Very interesting. Did you complete the install. What if the resistor is at 100% open, still safe at 32a? Any way to remote control this with something wifi based? Would be great to control my rolec 32a dumb charger for the charge rate remotely, so I could use my excess solar to dictate the value using Node Red or Home Assistant instead of a manual knob to turn. Though the manual option is still worth pursuing if no better solutions.

Hi I have a rolec smart charger and the EV app will not let me set a time for off peak electric, can I use a Shelly 1 on the smart charger, it's an untethered charger thanks

Great video. Wondering why you chose the CP connection rather than cutting the live feed to the control module itself? Controlling the CP wire means the LED indicators will continually flash when the charger is not in use. Although minimal, the flashing LED is consuming power. Controlling the live to the module would power off the control module, and just keep the charger in a state of readiness for when the module is powered up. Maybe this method would cause damage or issues though?

Hi, do you have details of the resistor values required for each of the 6, 12, 18, 24, 30 & 32A charging currents [on your Duty cycle - charge amps table], please?

Hello,can i contact you?

Very good video on mod for Sonoff Basic. I just completed the same for my Basic RFR2. Now, I have it attached to my GDO and can also use a 433 MHz remote to open/close the door. Of course it also have voice and manual operation.

super video ! butt i have bought an shelly 1pm and on that device the terminals are numbered/named different ! how do i connect that one ??

Good safety - much apprecierede you making the video available for us. Thanks buddy...!

Its interesting, do ypu know if there is a simular solution to the EO Mini (not pro)?

Wired this up to my rolec untethered unit. I've interrupted the proximity pilot pin. It works perfectly at telling my rolec to initiate charge because the car is connected to it, by while during an ongoing charge if I make the Shelly an open circuit, it doesn't disengage the charge session. Very weird

Many thanks I have an old dumb Charge master cp. This will solve so many problems. I can't identify a 12v supply within the Charge master to power the Shelly so will have to use the 240v. Eg Shelley unit power L / N 240v. Chargmaster control thin black wire switched through the Shelley i / O on the low voltage side. Is this correct as I need those beer tokens

Hi Skipp, Hope this finds you well, My 6 month old Sonoff basic R2 konked off ... I tried changing the relay, but it will not budge, it will not come back on (sadly the original relay broke off while desoldering it out) (Also there is no glass fuse, its seems to be a 5 band 10 Ohms 5% resistor in its place inside a heat shrink tube).. Anyhow Funny though 5 other Sonoff basic R2's switches have been working for over three years perfectly well ... And this new unit circuit broke and I cannot figure what component has popped. ... I'd be totally thankful if you could guide me on how to fix this.

The Shelley switch is only rated to 3.5kw so how is it safe for a 7kw Rolec?

Excellent video this. Did this mod in a Qubev dumb charger and works a treat!! Sod paying through the nose for a smart charger. All you need is a good electrician and buy the kit yourself. Government grant fitting is a gigantic rip off!!

On my timeswitch I connect the normally closed contact to a 1k resistor connected to the 12v output. Instead of the CP line being open circuit this makes the car believe it's connected to an EVSE in standby mode.

Дякую, потрібна інформація. Лайк!

@hotrex7 Am I right in assuming this will, when wired like this, will 'wake up' my MG ZS EV, like your video on the modified Sonos?

does 16A mean it wont work for a 32A EVE?

Thanks for the video. I was looking for any clues as to why my mode 3 controller is playing up. Do you what it does?

Why modifie the Sonoff? Just add a extra relais (110 or 230V) at the output for the same result.

Can I used this modification to run a 12v dc motor?

Hi - i have some questions: Im right that you using a 5V PWM Signal - to controll the Power output of the Inverter - wich PWM Frequency do you use ? - do you have connected it to the external or internal Connector of the Inverter ?

Hi Do you sell these devices? I've got a tattered Rolec..

Hi, I found this type on ebay is it the same? Shelly 1 -3.kw 230/16A ???

Great work. You could use a Shelly EM to have this feature and also the power monitoring and history. Moreover you could use power monitoring with another one placed on the house to trigger a disconnection in case of too much power pulled. I have done this in my house to disconnect AC and send an alarm before total disconnection.

Thanks for making this video. I didn't realise such a device existing. Perfect for what I need to add timed charging to an old Rolec charger.

Great video, any change of doing one sometime using a 7 kwh old chargemaster home unit, using one of these, Must be quite a few still working but not able to take a smart charge.

Thanks very useful video, quick question what are the crimp-on connectors you use called, they look very neat.

Suggestion for a slightly simpler way to do this mod. All of these steps are done on the non-component side of the SonOff Basic R2. 1) De-solder relay output wire to Neutral terminal (as you did). 2) Cut entirely through the pc board/trace at the point that is common between the fuse lead, and the relay output lead. 3) Route the de-soldered relay output wire from "step 1)" into the pc board's corner notch, and solder it to the relay output solder pad from "step 2)". Confirm that there is no continuity between mains/input terminals and output terminals. No need to drill holes, or relocate the fuse. Just one through cut of the pc board.

is it possible to operate also 230V on the output?

Brilliant and thank you. Just ordered mine.

Got mine ordered this morning. Thanks for the great info.

Another great way to smart your dumb charger and such small device is a winner

Wonderful!!

Excellent demonstration...helpfull! thanks!

Hi Bill, I’m very thankful for your great contribution on to how to resolve the issue that Rolec home charger and MG ZS EV have with scheduled charging. In particular I’m very interested in “MG Wake Up Board” that you made and demonstrated in your video. Is it possible to buy one from you so I can set it up within my Rolec home charger? I’d rather use your solution then Sonof smart Wi-Fi switch as my Wi-Fi signal is not good where the charger is.

I like your method. Moving the fuse makes this mod much safer. 👍

Good stuff, thanks (despite the vertical video 😉) . I think I'll do this and use Home Assistant with AlexxIT/sonoff so can integrate with Octopus Agile ToU tariff. Could also use the sonoff but cut the traces to make volt free and then use instead of the 5v powered board but without need for 5v supply? Edit: just seen the subsequent video 👍🏻

Useful, thanks. Would be improved by the video not being vertical

great vids, its there a way of buying this modified sonoff wifi switch ?

That was a really clear explanation. Thank you.

Hi Mate, I have a 32A rolec charger what sort of fixed resister I should be using? 220 ohms? What eating? Advice will be greatly appreciated.

Hi, I am searching for this information since 2 years... are you able to provide more Details regarding the PWM signal? I like to meassure the power consumption of my house via an industrial Smart Meter and send all necessary information via a RS485 wireless connection from my house to a 100m distance. I like to use the EEM Power Meter and Radioline modules from Phoenix Contact. They are easy to use. On the Location where the Inverter is installed I like to use a PLC to convert the signal to the inverter and to provide a WLAN network with a cloud monitoring. For that I like to use the Phoenix Contact AXC 1050 Controller with IO cards. These things are alle steardy.
