MQTT does not work reliable

Hello!

I’m running the newest HA and try to switch from FHEM to HA with my installation. i bought new TUYA thermostats and an openmqttgateway for my technoline TX29IT temperature/humidity sensors. I installed mosquitto-addon and tried using it. Everything works fine, alle mqtt-device are autodiscovered. I deleted devices from our neighbours. When i change battery on a technoline device, it gets a new random id. So a new mqtt device is created. How to deal with that? It breaks all bindings

All LaCrosse-TX29IT have Mqtt-model LaCrosse-TX35DTHIT, which is wrong.

Any hints or comments?
