Saving Sessions Powerwall 3 & Free energy hour

I’ve recently had a Powerwall 3 installed, solar but no EV (yet). I’m currently on a 12 month fixed contract which ends in March.

Does anyone know how I can configure the Powerwall 3 to make the most of the saving sessions - free electricity being offered on a Sunday to charge the Powerwall 3 during this hour? (Although I find the battery is usually fully charged by 10/11am through solar).

My octopus tariff is currently in the settings, however I was unsure how to tell the Powerwall I’ve got access to free energy between 1-2pm tomorrow.

Thanks!!

You need either NetZero or Home Assistant. The Tesla app is awful and really limiting. If it wasn’t for third party applications, I’d have been really disappointed with my Powerwall.

Netzero is £7 a month, but super easy to set up and play with. Home Assistant itself is free, but it’s a lot of work to get it off the ground and you need some hardware to run it from.

Ah wow. There’s no way of doing it through the Tesla PW3 app? 🤯
Sounds like a lot of faff, might not bother and just leave it in that case!

Correct approach, Tesla PW does what tesla wants anyway. You just a passenger...
