SolarSense 750 -> ESPHOME -> MQTT -> Cerbo -> DBUS -> VRM

Hi,

I just bought a SolarSense 750. Unfortunately, my Cerbo GX (on the roof) and the device (in the basement) are too far apart for a Bluetooth connection.

I’d like to share 2 personnals projects I wrote (with Claude’s help):

  • ESPHome SolarSense. You just need an ESP32 with Wi-Fi near the SolarSense, and all the data will be sent to an MQTT broker, for example Home Assistant. I’m using Home Assistant on my side, but it should also work with the MQTT broker running on the Cerbo.
  • MQTT SolarSense to dbus. You install this one on the Cerbo. The script creates a device on the Cerbo with live data from MQTT, so VRM can see it too.

Have fun !
