Shelly Relays - MQTT, Coap

I’m wondering if anyone has every tried using a wifi Shelly relay ( to control lighting with a Roomie Remote? I would be interested in this use case. The Shelly relays are small and can be placed wired into the back side of existing light switches around a house. Or Roomie Remote could add support for MQTT or Coap which the wifi relays support. Any thoughts?

I would also like support for Shelly devices. Anyone got this working?
