Home Assistant Victron GX integration based on the MQTT protocol
In Apple Home through HomeKit Bridge
What HomeKit Bridge makes of each kind of entity this integration creates, read from its source code. A device only gets the ones that apply to it.
| Entity | Shows up as | Note |
|---|---|---|
switch | Switch or outlet | |
binary_sensor | Sensor (motion, contact, leak, smoke…) | |
sensor | Sensor (temperature, humidity, air quality…) | |
button | Button (as a switch) | |
select | Mode picker (as switches) | |
device_tracker | Presence (as an occupancy sensor) |
What people report

| Victron Cerbo GX / Venus OS GX device | Works Local | Local MQTT; GX firmware update entity added, skip behaviour fixed in 2026.9.6Saved copy… mqtt-explorer as described in the docs to extract the topics I care about. ### Describe the feature After updating to v2026.9.4 if there is shown the new Victron Energy Firmware update for the GX-Device (Venus OS), and you skip this update, after every reboot of HA this Firmware update is shown again. This behaviour is different to other Updates, where, once you skiped them, they doesn‘t appear again.

I am using an IAMMeter WEM 3080T as 3 x single-phase CT meters, so I can check the EV and grid power and use these to adjust the EV charging rate multiple times a minute. Therein lies the problem, the Iammeter-http meters only update every 60s. I have tried to set up the Iammeter for MQTT, which will allow 6 second refresh rates. I tried to load Mosquitto into HA, and it's just not working. So, given your vast MQTT experience, can I have two MQTT brokers … Excerpt saved from GitHub on 2026-10-23. | Issue #95 · 2025-08 |
