Domoticz restarting repeatedly rflink

Post by Domv31 »

Version: 2026.3
Platform: RPI3B RapiOS trixie 13.7 32GB Sdcard
Plugin/Hardware: rflink 433.92MHz

Hello
I am new on the forum
My Domoticz is running since years but since 3 months Domotics is restarting Rflink nearly every hour. It is may be related to trixie because i was previously on bookworm
I am using the official Raspberry supply and i confirm the voltage at USB output to Rflink is 5.1V (at least when i measure. Didn’t manage to get the voltage during Rflink restarting event with a scope)
Nothing else connected on other USB ports
The sensors from Rflink are recorded nominally every 5mn
Any idea why domoticz is doing that?

Short extract from the log (No errors only status reported in the log)

Code: Select all

I have another Domoticz 2026.3 running on a rpi4 2GB trixie 13.7 with Rflink rev 48 and RDS RTL dongle running nominaly, so this behaviour is maybe linked only to rpi3b with trixie.

That was my first reaction, a problem with your power supply.
Can you exchange it with another to see it that solves it?

I have attached such a devices for years and have no such error, so it is not related to domoticz.
But it could be related to something the RFLink is receiving also that crashes internally ?
