Tasmota switches stop working after few hours from Domoticz. MQTT issue?

[Jane]

When system starts. All works fine. ZWave, RFXCom, Zigbee and Tasmota devices.
But after about 4 hours the tasmota switches reacting slower when switchting on/off.
1 hour later they stopped reacting when on/off.

Hopefully someone has an idea to resolve this.

Version: Domoticz 2023 2
Platform: Raspberry pi 4b 4gb ssd

1 hour later they stopped reacting when on/off.
The incomming data is receiving correct, like electra ursage. kWh etc.

After restart Domoticz it's the same after a while.


I have problems with my Tasmota switches after update to new system.
Before I had OpenZWave and now Z-Wave-JS-UI.
For Zigbee2MQTT and ZWave-JS-UI, I have MQTT Auto Discovery Gateway with LAN interface.
For the Tasmota devices I use MQTT Client Gateway with LAN interface.
Tasmota with MQTT Auto Discovery did not working.
Maybe the problem is the 2 MQTT's installed at same time.

Before on old system I had OpenZWave and no MQTT auto discovery.
I testing with powerswitch tasmota versions 12 3 1 and 13 2 0.
Before I was going from old Raspberry pi 3b I had run a test Raspberry pi 4b.
After running ok for a few weeks, I was stept over to new main raspberry pi 4b with data from
the old Domoticz on the 3b.
I had updated the ZWave devices from OpenZwave to Z-Wave-JS-UI.

For test I have also run Home Assistant. The Tasmota device there working ok. !!

I have now running a script who calls domoticz to switch on a tasmota powerswitch.
and check how long it takes that the device is going on.
When to long, like 2 min or not on, automaticly restart Domoticz.
But this not nice

I use some Tasmota devices because the http calls that I make to the devices, outsite the raspberry.

I also tried to use tasmota devices with MQTT auto discovery, but it didn't work.

I found the solution for my problem.
I believe MQTT Auto Discovery Gateway with LAN interface and MQTT Client Gateway with LAN interface have a problem together.

Instead MQTT Client Gateway with LAN interface I have installed Autodiscovery of Tasmota devices Tasmoticz.
Now the tasmota devices automatic added.

The problem is gone now. It's running 4 days without problems.
