Great video as ever. Although debatably a shame that you can't avail of Bulb EV tariff (who don't actually require wheels on the batts and state as much) at 11.31p and 37.76p presently in our area. Of course who knows what's going to happen in a fortnights time when absorbed by Octo, but I'm assuming if you're already on such a tariff, the Octo equivalent would come into play.
very interesting video. I have been trying to work through this myself, but I cant seem to find the solar forcast integration for HA. what are you using, is it via hacs? thanks ken
Hi Ken, thanks for watching and the comment. I'm using solcast, and the integration is done via HACS. You need to register on solcast and get your free API key first though. There is also 'solar forecast' for HA, which I know lots of people use. I found that it occasionally dropped out though.
Could you set 7 hour charging window overnight? it will stop when BMS reaches upper voltage and, I think, won't discharge within charge window. You could also set current at ~15-20a, so it charges slowly over 7 hours.
Yes it will discharge when capacity is at 100% (or whatever you set). I've seen this happen which is why I have the automations set like this. If you can make another automation work for you, then that's great - but for me this is what worked best. Thanks for watching and taking the time to comment.
@@gordonmarkus I didn’t… my car doesn’t arrive until next month and I could sign up anyway - at no point was I asked for any documents. I know a few guys on Go without an EV… obviously they might take you off it at some point if you can prove you have one, but it hasn’t stopped those guys I know from signing up with just house batteries. Just visit the link and sign up, worst case they find out at some point and out you back on a different tariff (though the new flux one looks interesting for summer).
Hi, can anyone point me at a tutorial for installing solcast into HA and then charging overnight based on solar forecast please? I have my inverters communicating with HA using waveshare devices and wills106/homeassistant-solax-modbus. Theres an excellent video by Jev Burchell setting out the theory here:- th-cam.com/video/fF0odNXTx48/w-d-xo.html&ab_channel=Jevjev . Sadly the promised follow ups, ie practical instructions as to how to install the whole thing, have not materialised. I'm a total HA noob. Any advice would be most welcome. It appears that there are currently issues with the Solcast integration in that the person maintaining it (oziee) has erased his github account.
Hi, this video might give you some idea of how I use the HA automations to charge based on solar forecast th-cam.com/video/aN5vFQm4vpU/w-d-xo.html As for installing Solcast itself, I think I just did it via HACs. You need to create a Solcast account and get your API key first though. Also note that you'll need to run an automation to refresh Solcast now, I think for new accounts you get 10 polls a day, so set it to poll every 3hrs.
fantastic video Gordon, thank you for making this!
I think I eventually sussed that when you say kW you're actually talking about kWhrs. Can you confirm, please?
Possibly, apologies for any confusion. Nobody has picked me up on that before :-)

@@gordonmarkus Thanks Gordon, I have that installed now.

How do they know if u have a car or not? Do you have to give some kind of proof that you own one?
Yes, you have to provide documentation of ownership.
