I have been playing around with my Tesla Powerwall 2 and Solar install for the last few weeks and managed to get some interesting results using a RESTful sensor against their API which is exposed as: http://[Tesla Powerwall IP address]/api/meters/aggregates This provides JSON [image] To get the…

Got it connected. Thanks for the help. I connected to the TEG AP and ran the wizard to set it up with my WiFi credentials (instead of the cellular connection it was set up with originally), then restarted it and it started transmitting through my network. Set a permanent URL and now Hassio happily r…

Matt glad you got it going, I used the Hassio builds for the components under the config directory - this was a migration from a standalone pi Hass implementation (all in one build) I am looking at getting the hot water from solar rather than gas when the battery is topped up and I start exporting…

Hi Dave, Glad to see that a start has been made on this! I had a PV array and PW2 installed last month and really want to optimise how we’re using the power. I’ve installed a couple of storage heaters and networked them on Smartlife plugs, and have a wifi switch on order for the immersion heater. …

Well, I see I have some way to go here! I believe I can use IFTTT to operate the switches for the heaters in response to webhooks. I don’t yet understand how I can implement the sensors Dave has described here in order to trigger the webhooks, based on what’s happening with the Powerwall. Here’s t…

I tried IFTT but it was too slow, so I now use Node Red for logic flows - this is an example where the PW is putting power back into the grid (typically at 100%) so I switch on the electric hot water to use the excess power - it uses zwave to switch on my electric hot water heater and switches it of…

This is a more exotic flow, this checks at pre-determine morning/evening times whether the PW2 has enough battery (set at 50%) for 20 minutes electric hot water, otherwise switches on the gas hot water (using another Zwave unit to controller gas heating/hot water) Also monitors HA to check whether …

Thanks Dave. That does help. Where are you running Node Red? And the code you have described above, is that written in Node Red as well, or into the HA configuration?

I am running Node Red on my Hass.io implementation - the flows are in node red, they read from the PW2 directly and use HASS to control Z-wave devices

So my PW just was installed, but it doesn’t appear to be on my network. The installer’s never asked for my wifi password and its not hardwired with ethernet. Am I out of luck?

probably not; does to device appear in the Tesla app? in which case it is talking to Tesla somehow, maybe via GSM. Have a word with the installer and see what he has done; there is an ethernet port inside the gateway which you could use a powerline adapter to connected to your network. I wouldn’t r…
