Exactly the issue... which is why I built my own control systems.
No way! A commonly used digital DS18B20 temp probe costs less than £5. Someone is taking the Michael there :(
But you don't need AI for the above level of control. All of that could be achieved if you have programmable...
:eek: Personally I'd be cautious about putting that info on a public forum... but maybe I'm just paranoid :unsure:
(or maybe you're really away in February and will be sat at home with some weapons of mass-destruction for anyone who might be tempted to burgle?)

A hybrid inverter will have its own power meter or CT to control export power, so when it runs on battery it doesn't export. But then you add an EVSE which claims to be solar compatible. It comes with another custom...
Inevitable losses. Most will be lost in the conversion from AC to DC within the charger. Some will be used to heat the batteries to a suitable temperature during charging. Some will be lost powering the vehicle's electronics. Some, hopefully a smaller amount, will be lost as heat in the...
Doesn't sound excessive to me - depends on how much you drive and/or use electricity around the house. Just checked... we're similar to @Tig170 having used 9.8MWh so far... but fortunately we generated 10.5MWh from solar in the year to date :)
Stumbled across this announcement...

Seems like over 10,000 Powerwall 2's are being recalled due to fire incidents. I've no idea whether that...
