problem with RF24 and switching relays

[MHofer]

Hello,

I have a problem with nodes that switch a relay, after switching the relay, the node is often no longer accessible and thus the relay is no longer switchable the error message is:

2019-02-10 17:01:33.737 Error: MySensors: Command not received by Node !! (node_id: 11, child_id: 4)

I have the problem with several knots independently of each other

MySensor 2.3

@mhofer The serial log of the node might reveal what's going on with the node.
It could very well be the inductive kick from switching the relay that resets or hangs your node.
How is everything connected?
