As far as I know, unless something has changed recently, you need BOTH the receiver and thermostat. the receiver reports the temperature, but it actually comes from the thermostat - I think there’s some direct communication between the two. I guess there may be a way to send a MQTT payload to the receiver from your server, but this direct communication isn’t documented and is way above my ability to find!
Yep, but as above, its a bit strange, the receiver reports this as
Yep, it all works two way. The boost mode is a bit finicky to get to work, but @Steveuk and I have both implemented this.
Yes, if you connect the SLT and SLR to your z2m instance it works direct. I’ve not got, nor have ever had, the hive hub.
Scheduling is a bit fiddly, there is a schedule mode on the thermostat, but this doesn’t play nice with HA control… see a long post further up the thread where I’ve set this up - you could also try something like Schedy.
Overall I’m pretty happy with the hive thermostat/receiver now, though, now I understand more (and am much much better at esphome than I was) I might next time go with an ESPHome relay instead…
The redeeming feature of this hive system, in my head at least, is that if my server goes off, i lose local wifi/z2m/everything goes wrong… at least then the SLT and SLR are still working together…
