Actually yes it's 2 wires to the thermostat, but bridging those won't start the boiler, it's using the ebus protocol for communication. I doubt you can connect anything but ariston's own thermostats there. As I said before you can use the other 2 contacts in the boiler for on/off operation, but you 're giving up all the smarts the boiler has built in, and thus efficiency.

Each row is one report from a GitHub thread, an integration’s docs, or r/homeassistant. Check the date and the linked source before you buy.

In ReReHome

Once Home Assistant’s HomeKit Bridge shares it, this device reaches Apple Home as a HomeKit accessory behind your Home Assistant bridge, so ReReHome shows and controls it like any other.
