IFTTT how to set the dimmer level?

Create a virtual momentary switch in smartthings.

In your IFTTT applet set this new virtual switch as the “that” to turn on with ST.

Back in ST, create a smart lighting automation. The switch you want to control is your real dimmer switch. Set it to “turn on and set level.” The trigger is your virtual momentary switch.

This way, when your air sensor does whatever you set in IFTTT, the virtual momentary switch in ST will turn on (momentarily). Your smart lighting automation will set the dimmer level of your real dimmer because the virtual momentary switch just turned on.
