Controlling an Inventer sMove decentralized ventilation system via HA and Shelly

Hi guys,

i wanted to show you how i integrated my decentral ventilation system from german company Inventer into my Homeassistant using the 0-10v interface on the sMove Controller.

Only thing you need is a Shelly Dimmer 0/1-10V PM Gen3, make sure NOT to get the other Shelly 0-10v, since we need an analog 0-10v output from the shelly.

  1. You connect the Shelly 0-10v output to Interface 2 of the sMove controller:

  2. In the Manual of the sMove Controller there is a table which shows, the voltages to apply for each ventilation mode/speed.
  3. Create a select-template in HA for all Ventilation modes.
  4. Since the Shelly Integration in HA does not fully support the Shelly Dimmer 0/1-10V PM Gen3 yet, you cannot control the output voltage via HA directly. So you need an automation that issues rest_commands to the Shelly like so:

you also need the rest_command configuration, which also does the conversion from ventilation mode to voltage:

This is a sample for rest_command config:

rest_command:
waschkelller_lueftung_aus:

method: get
waschkelller_lueftung_druchlueften_1:
