There are two paths, the first is easy and the one I would recommend.
Alt 1
Make a backup of the database files:
/var/sqlite/*.db
Re-install your raspberry from scratch using Raspbian 11 following the default installation instruction including configuration of ThermIQ_MQTT. When everything works, copy the db-files back and overwrite the new db-files. Then go back to Settings->Installation and do “Update database” to ensure that you have latest db-format.
Alt 2
This is an outline of update in place (but not verified to work):
– Go to Settings->installation/Backup and make sure that ThermIQ MQTT is selected as Enabled Modules
– Open /opt/etc/Thermiq_Linux.ini and make sure that poller_ThermIQ is disabled and poller_ThermIQ_MQTT is enabled
[poller_ThermIQ]
enabled = 0
[poller_ThermIQ_MQTT]
enabled = 1
– Go to Settings->Poller and configure the ThermIQ_MQTT, make sure you configure MQTTClient_Name with your ThermIQ name (ThermIQ_”YOURMACADR”) and MQTTNode etc according to your setup
