Domoticz stops responding when MySensors plugin doesn't receive information Topic is solved

[Lightning707]

Hello,

I have created a controller for my roller shutters (and some other devices) with relays, controlled by an Arduino. For this I use the library of MySensors.
In Domoticz I use the Plugin "MySensors Gateway with MQTT interface".

For a yet unknown reason, the LAN connection of the Arduino is sometimes interrupted. I am still investigating this problem further.

However, the problem is that I notice that Domoticz appears to freeze after a while (+/- 5 minutes) when the MySensors plugin does not receive any information.

The only (error messages) I receive are the following:

Code: Select all

2024-09-25 11:45:22.347 Error: MySensors MQTT hardware (23) nothing received for more than 1 Minute!....
2024-09-25 11:45:23.350 Error: Restarting: MySensors MQTT

Followed by the status messages below, indicating that the connection to my broker is working correctly.

Code: Select all

2024-09-25 11:45:23.532 Status: MySensors MQTT: Worker stopped...
2024-09-25 11:45:24.545 Status: MySensors MQTT: Connecting to localhost:1883
2024-09-25 11:45:24.760 Status: MySensors MQTT: Connected to: localhost:1883
2024-09-25 11:45:24.775 Status: MySensors MQTT: Connected to: localhost:1883

This processes of the above messages is repeated several times. But after a while, Domoticz's web page stops responding without error message.
All I can do then is restart Domoticz via the command line and disable the MySensors plugin.

What is the "Data Timeout" setting of the "MySensors Gateway with MQTT interface" hardware gateway? (menu Setup-Hardware) It should normally be "Disabled".

The data timeout was set at 1 min. I disabled it and that indeed seems to solve the problem. Domoticz doesn't seem to crash anymore. Thank you!

Although I still don't understand why Domoticz crashes on this. Doesn't the timeout ensure that the connection is automatically restored when the MySensor is back online? Or should I set the timeout setting higher (e.g. 15min) to avoid overloading Domoticz??

Domoticz has contact with the MQTT Broker so only when MQTT Broker is sending no info you should have issues. But I dont know how this MQTT for Mysensors is implemented. Perhaps check it on the Mysensors.org forum.

And indeed if a time-out setting is needed I would set it to 30 min or so.
