I recently bought a WattBox WB-700, and I was surprised to find that the existing WattBox integration didn’t actually work with my model. After digging into the HTTP API, I decided to build my own integration for Home Assistant.
This custom integration supports the WattBox 300/700 series (WB-300, WB-300VB, WB-700, WB-700CH).
Features so far:
- Control outlets individually (on/off)
- Reset outlets (including “reset all”)
- Pulls outlet names from the WattBox config
- Sensor values (voltage, current, power, etc.)
- Polling interval configurable
- Config flow (no need to edit YAML)
You can add it to HACS as a custom repository under Integrations. Feedback is very welcome, especially if you have a different WattBox model and can confirm compatibility.
