Brink Renovent Excellent 300 Ventilation System control using HA

Hardware
1

Hello all,
I am running HA fore some months now and have integrated some Zigbee, Zwave and Tasmota WiFi sensors running on ESP8266. Pretty cool for a HA rookie :wink:

My new project is to control the speed of my house ventilation system using HA / node-red based on the CO2 levels in my living room and kitchen. The Brink Renovent Excellent 300 system is controlled with a physical switch that control the 3 speed levels and a OFF state:

Can somebody advice a piece of hardware that can integrate with HA that can replace my physical switch? I think i need some sort of relay switch. I searched for a good Sonoff option but am unable to find a relay switch that has three pins. Or can i build a switch from an ESP with Tasmota?

Thank you in advance.

Very interested in this too, my current controller is somewhat programmable with a colour display, but I need to make it run on hass.

I rebuilt my unit into a Brink Renovent `plus’ version, allowing 0-10v control. I’m using a Qubino Z-Wave 0-10v driver to control it based on PM, Rh and CO2 level in my house. Using normal Yaml automations to do the calculations and drive the controller. Works very well.

Before the rebuild, I was controlling the unit using Fibaro relay, but those relay contacts often failed causing the unit to be stuck in certain ventilation position.

would it be possible to provide more details of how you implemented this (in particular, how did you wire the dimmer?) ? thank you in advance!

hi Arthur,

Did you use the 24V from the unit to power your Qubino Z-wave 0-10V?

I used this relay wired directly though RJ11 to X2 port as in your wiring schema

Can you please give more details about the connections?

I have a brink 400 model. I hope this works fine for me also.
