OK I have enough temperature sensors to tell if a window has a draft blowing through it, now to do something with them.
The worcester boiler with RF thermostat should be picked up by RFLink but it fails to do so, what are my options?
Attached the thermostat control lines to a relay and just open and close it via a esp
Install Hive, wil this work with domoticz?
Move to openhab in the hope that the RFLink works under that?
Just leave the heating alone?

In reality you have many options if you're willing to put the effort in. You could use a Z-Wave boiler relay and thermostat for example, though a better bet would be to also use controllable TRV's. I once spent ages writing control routines for multi-zone heating using Z-Wave TRV's, thermostats and a boiler relay ( plus detecting when the things inevitably stopped working for some reason. ) Not a cheap way to go though.
In the end I just got a Honeywell EvoHome system, which works well with Domoticz and for me has paid for itself in a couple of years... but YMMV. It takes care of all the "detecting a window open stuff" and is much better than Hive and the like because it allows you to set schedules for individual rooms. Not even sure why Hive is "a thing" if I'm honest - it's just a remote controlled thermostat. You can still only set the temperature of the whole house at once.
EvoHome isn't cheap, but for me it's been brilliant, and saves hours of messing about trying to do something bespoke.
To add even more options if you have a Worchester boiler with the EMS bus you can also read the boiler parameters etc with an Arduino or ESP8266.
