[TS0203 / _TZ3000_26fmupbb] no data connection after pairing #29547
Description
What happened?
On joining of TS0203 sensors, sensor is found an integrated to the network showing the correct device. No connection to device is established and no status information on the device are available in frontend.
What did you expect to happen?
After joining the network the device should expose firmware, contact status etc.
