After start second ZigBee2MQTT the first send only a few minutes to MQTT

[rt1970]

Description of the issue

I have two ZigBee devices in different locations: my home and my vacation home over VPN.
My home is an HMG-01, and my vacation home is a SonOff bridge.
After I launch the second plugin from the vacation home, the first ZigBee2MQTT sends messages to Mosquitto for just a few minutes.
After that, the devices disappear from Mosquitto.
