Shelly i2c

The Shelly GPIO for their temp sensor is i2c. I have read that some people have been able to us dh11 on this bus too. Has anyone tried connecting more sensors on that bus? I am thinking of adding a second blank switch next to my light switch with more sensors like lux, temp, pir, co2 etc etc.

I was about to build an ESP32 module like the bruhaus one but figured that if I have a Shelly in each light switch then I already have an i2c bus ready to go!
