Thanks Chris! That fixed it!

For what it's worth I'm not seeing 60amp max output from two Powerwalls. Details: I have two AC Powerwall 2's . My whole home 200 Amp service, as well as the Tesla Wall Connector (vehicle charger 60amp breaker - 48amp draw) is backed up. I can draw a continuous maximum of 10.1kW from both the...

I use TMPFS on my Raspberry Pis to do exactly that. Mount a ram drive and use that to save the write cycles.

Thanks Chris!

You could try a few things. 1) I assume that your gateway is connected over WiFi. If that's correct, try connecting it to your network via an ethernet cable. I realize logistics may be difficult. You could setup a laptop with a DHCP server and connect your laptop's ethernet directly to the...

Other uses: -reduce or eliminate reliance on dirty grid power during low solar production times: night, rain, snow, etc. Random thoughts: -The powerwall isn't going to charge your car very much. If you are only getting one, that's < 14kWh of storage. Your car is anywhere from 60-100kWhs...

-Typically you are only posting data to the gateway when you want to change a setting. -Otherwise you are doing a http get to a specific/unique URL without sending any data. There are a few requests where you need to post data: authentication for example. Here you need to send data in a...

Ah! I see...For that particular request, you don't have to supply any data. You can hit this URL http://192.168.xxx.xxx/api/meters/aggregates with a wget, curl, or simply your web browser. (replace the IP with the IP of your gateway).

That's true...

Agree! If anyone here has TOU enabled, please reach out to me via private message so we can get that documented.

Sure, here's an example response from the Powerwall 2 gateway. This is similar to a hash (in perl) or a dictionary in Python. They are key-value pairs. https://raw.githubusercontent.com/vloschiavo/powerwall2/master/samples/api_meters_aggregates.json Cut and paste into a JSON parser like...

Hello everyone. I'm currently working on documenting the local gateway API for the Powerwall 2. Additions, feedback, corrections are welcome! vloschiavo/powerwall2 Additionally I'm interested in adding the API calls for Powerwall via the Owner's API to Tesla's servers (ala Tesla Model S...

Thanks CDragon. It would be interesting to see the current code for the v2 protocol, I'd like to stop charging via a call to the Tesla Vehicle API instead of manipulating the wall connector.

I'm getting similar results. I'm in the US and have just purchased (March 2018) a TWC, which presumably has the latest firmware. The messages I'm getting on the RS-485 are below - additionally the RPi master never syncs with the slave TWC. 20:29:52: Send master linkready2 [email protected]:29:52: c0 fb...
