Hive heating hub, change occupied heating set point with automation

Hello.

Ive spent the last few hours trying to figure this out and done lots of searches but I’m still stuck.

situation is…

I have a hive heating thermostat connected via Zigbee2Mqtt and can control the target temp via the Lovelace thermostat no problem.

However I want to have an automation lower the temp to 7degrees at 2100 hours, sounds simple but the only Actions in the automation UI are “Temperature set point holds” and “change HVAC mode”. There is no option to change the “occupied heating set point” even though it is exposed in Zigbee2Mqtt.

any help appreciated
