A bit of a late reply but some time ago I also asked about this in the domoticz forum. "They" don't see the problem although I clearly see in the domoticz sources that this stupid behavior is intentionally put in there. I compiled domoticz with a few changed lines and then it works. Unfortunately I have tons of Mysensors issues, mainly with the NRF2401 (yes, from multiple sources, good psu, capacitors etc.) so I am forcefully have to abandon Mysensors and migrate to ESP8266 nodes to finally get a stable sensor network. Therefore I'm also more flexible with domoticz.
