Telegraf config to query a Tesla Wallbox Gen 3

Sunday, December 10 2023 · Lesezeit: 3 Minuten · 454 Wörter

Here is a sample configuration file to query a Tesla Wallbox Gen 3. It collect’s wifi, lifetime and vital stats. It’s designed around Europes three phase power grid. Just fill in your desired output block and you should be good to go. Pass in the IP address of your wallbox as environment variable.
