About powerwall-dashboard-mcp

powerwall-dashboard-mcp Quick and easy docker container that creates a MCP server that connects to the default influxdb 1.8 of the Powerwall Dashboard project. This allows you to use your AI/Agent of choice to ask it various questions about your Tesla Powerwall and/or solar system. See example questions and answers below.

AI Disclaimer: Yes, I used AI to create this. Use at your own risk!

Edit docker-compose with your grafana location:

Modify INFLUXHOST, port and db names should likely be left alone. If you are exposing to the public, be sure to set the MCPAUTHTOKEN. Save the file and exit (ctrl+o, ctrl+x).

The MCP server should be accessible by http://:8765/mcp

You can add this to Hermes Agent, Open WebUI, Claude, etc. Response is only as good as the agent and model that you use! I found that openwebui did not tool call enough to get the good responses. Hermes was extremely good at tool calling and responses.

Example questions and responses (all via Hermes with Qwen3.8-27B IQ4KS ikllama)

After feeding Hermes PGE historic rates as a memory, I had it guestimate my current ROI:

Asking Hermes to compare past 3 Mays and what the correlation to generation was:

Asking Hermes if buying a Powerwall was worth it (yes, but long ROI on NEM2, doesnt take in account outages)

Fed Hermes the exact dates and cost of cleanings to pull from PWD (via hermes connected to my Discord):

Hermes even used its own script to output a graph outlining it all:
