Help choosing wireless OpenTherm gateway for HA :)

I’m a bit overwhelmed by the information I can find online, and it’s a bit hard to choose.

I want to find a device that implements OpenTherm, will work either with Zigbee or zwave, and could be controlled by a temperature sensor through HA.

Can you please recommend devices that do not require a lot of tinkering/flashing/soldering?

Hardware that I have right now

  • combi boiler with OpenTherm support
  • home assistant on raspberry pi with Zigbee and zwave setup
  • temperature sensor inside a room that is connected to HA
