[SOLVED] No message after few hours

[A Former User]

I'm testing the network with domoticz on a raspberry and a couple of arduino nano with dht11 sensors.
Everything works fine, but after few hours it seems my nodes stop transmitting. Robooting arduino solves the problem.
Any idea?

@gerseun DHT reading issue? Transmit batteryLevel or some other heartbeat message every hour to find out.

I am a newbie with arduino, what is a heartbeat message?

[m26872]

@gerseun I just mean anything that tells you it's alive. Any kind of message sent to you at a known interval. It could be a flashing LED, radio message logged by controller or whatever.

@gerseun Are all your radio id's unique?

I think I solved it.
The reading from the sensor is good bad the trasmission stop randomly, so I tried to add coupling capacitors on the wirless module.
It's more then 24h without problem so I think this solves it.

Yes not using capacitors usually causes problems. Great that you got it working. Thanks for reporting back!
