WorkOS
The modern identity platform for B2B SaaS. The APIs are flexible and easy-to-use, supporting authentication, user identity, and complex enterprise features like SSO and SCIM provisioning.
As for other tricks, what are you using to grab the API data? I use the python library pypowerwall and have been graphing the data with grafana (see dashboard example).
I’m using Node-RED to make https calls to the PW APIs documented here - https://github.com/vloschiavo/powerwall2. For now I’m just using the basic login/token API, the battery charge (soe) and the meters/aggregates to grab the current generation and the totals. It looks like the current generation does not match what comes from the app either (I’m timing the calls to be every 5 minutes, starting at the top of the hour, so should be about the same time as the app)

- Hi. We just got solar from Tesla. 14.4kw system and 3 powerwalls. Is there a way I can see each powerwall individually? All I see is the percentage and x3. I’m trying to balance it to where we run on powerwalls all night and have enough reserve power to get through a short power outage if necessary.
