Haha, no. But I know someone who was part of the OpenTherm development.
To quote him:
OpenTherm exists because Plumbers don’t trust Sparkys and Sparkys don’t trust plumbers.
OpenTherm is easy to install but “stupid” as hell and not adaptable to modern needs mostly, especially if you consider modern heating concepts like passively heated houses, heat pumps,etc.
That’s different from KNX(or Modbus in that regard)- They are much broader in their appeal. Singule use/walled garden systems are always a bad idea,imho.
The good thing is: You can easily replace OpenTherm with KNX.
Afaik there are Gateways that mimic Opentherm towards the heater so you can use KNC for the actual control.

Ah, good but not nice to know. OpenTherm is really popular in the Netherlands. Not nice because I know loads who have such a thermostat. Oh well.
