I’ve pushed a update to the MQTT Devices driver. Given the reports of instability and disconnects by @raisingskell and @gst, I’ve tried to to beef up recovery from disconnects.
If the connection with the broker cannot be made at driver startup, or is later lost after successfully connecting, the driver will retry every 15 seconds to (re)establish the connection. Once established, all topics will be (re)subscribed. The status field in the creator device will tell you of any reconnections, and you can also look in the device History to see prior status changes.
Also, remember that you can tap the Refresh button at the bottom of the creator device Controls screen and this will force a disconnect/unsubscribe all/reconnect/re-subscribe all sequence.
New driver version: 2022-11-20T02:05:26.759176946
Please let me know of any further issues.
