Syslog says a lot of: "mysgw: Client 0: 0:0:3:0:18:PING
with an occasional "rsyslogd-2007: action 'action 17' suspended, which is probanly about the log being spammed by MySensors.
It uses a 3.3v stabiliser board.
Tried different power levels in settings (usually use low power because it works better for the cheap Chinese knock-offs)
Tried external 5v power supply.
My nodes are saying 'FPAR: NO REPLY'
