No long term statistics for mqtt2zigbee climate control

In my HA I would like to have long term statistics for room temperature. I have zigbee radiator valve connected and configured with zigbee2mqtt. I can control the valve (read temp, set destination temp, turn on/off) using UI, but the long term stats are not available for temperature. The weird thing is that stats are available for this device’s link quality (but not temp). How do I fix that? Is it mqtt integration issue, zigbee2mqtt issue or something else? Is there any workaround without having to modify any of those components (eg. some add on config)?
