Ble and RTS Somfy

Noob question. Is it possible to support ble and somfy rts on one esp32?

I would say yes depending on the usage level of both.

Only ble thermometer reading and somfy roller shutter control. I understand that I need to create a ble + rts compilation?

If you scan for Xiaomi thermometer with the default every 55s it should be ok.

yes you need to create ble + rts environment by merging both.
