| OpenTherm Gateway (OTGW) with Intergas boiler | Works | Maintainer says it should work if the OTGW supports the boilerSaved copyIf the OTGW supports the Intergas, it should work with Homebridge OTGW. There are some Intergas boilers and one thermostat mentioned on the OTGW device list: http://otgw.tclcode.com/matrix.cgi. See the README for how to setup Homebridge OTGW.
