This seems to be due to the fact that the value of the MySensors child is purged upon domoticz restart, and the WriteToHardware function uses `FindChildByValueType(V_IR_RECEIVE);` to find the child (and value to send).
After domoticz restart:

After child refreshes IR code:

So unless I force the MySensors node to periodically refresh all possible codes, I would need to manually set them with dzVents upon domoticz restart. Is that possible?
Thanks!
