Victron is cool, Home Assistant is cool but they don’t work together pretty well. Until now.
I’ve found other different ways of connecting them together, but, they didn’t work reliably for me.
With Modbus you have to poll the Venus OS every 5 seconds and sometimes you don’t get all the data. At least for me that was the case. Like this one here.
I also found the victron integration hass-victron but this is using modbus too and there were times I had to restart the integration to get data again.
There must be a better way doing this.
Venus OS has a built in MQTT Server, that should be usable.
With MQTT you get instant data, when the venus OS updates. And that is way better than 5 Second Modbus polling with missing data.
What you get, when you’re done:
What you need:
- Home Assistant
- MQTT Server (use the Add-on)
- Samba NAS Add-on for access to the configuration files
- Venus OS running on a GX device or raspberry
- MQTT Explorer (find it here) can also be used as an Add-on
Venus OS and Home Assistant need to be on the same network!
Steps for a working setup
- Enable MQTT on your Venus OS
- Check the MQTT with MQTT Explorer
- Install MQTT Server on your HA
- Install Samba NAS on your HA
- Configure the bridge Venus - HA
- Check the Bridge with MQTT Explorer
- Create the keep-alive automation
- Check data coming in with MQTT Explorer (Topic will be venus-home/N/your-venus-id/#
- Create all needed sensors in your mqtt.yaml
- Smile
- Maybe change your recorder settings so your HA database can keep up
Follow this guide for setting up the mqtt bridge connection between your HA and the Venus OS
Scroll down to Bridge your Victron Energy Venus device to your MQTT server in Home Assistant. (The internal and direct links on this page don’t work.)
Alternative guide for the initial setup.
After you manged that you need to configure all your sensors you want to see in your home assistant.
Be sure to change the device id (your-venus-id) to the id of your system.
Here are the sensors and switches I am using. this list is far from being complete and every solar setup is different. I have a cerbo, a Multiplus, a MPPT solar charger and an EM24 smart meter.
I did combine these sensors into devices, so I have all the sensors in 3 devices.
Please Add your sensors, switches and number inputs to this list.
