it may be a more universal solution for the node/switch to use the request(uint8_t childSensorId, uint8_t variableType) function and resend the command to the node/relayActuator after a timeout. This is what @jkandasa mentioned in his post earlier. Still if the node/switch receives the request() it does not know what sensor sent it. If this was contained in the message variable we could implement a fairly robust solution to this.
@DaTTcz Hi, Thank you so much for your interest with MyController. Try disable serial gateway on MyController and unplug. I hope nothing will happen. If you see any errors on mycontroller/log/mycontroller.log please report. Thank you for your support!!
@hoegaarden_bier Yes, It is possible to migrate across platforms (but I never tested across platforms). It should work. Can you list complete error trace?
What is your previous version and new version?
