I have a Zigbee network with lots of lights (Ikea, Hue) and sensors.
I am looking at replacing the dumb TRVs on my radiators with Drayton Wiser ones. I am able to trigger the boiler programmatically and I just wondering what the pros / cons are of just integrating the TRVs into my existing setup vs putting in a whole Wiser system and linking to it via the HACS integration.
I can see a few advantages to just using the TRVs in my existing stuff
- Cost ( ) I would end up needing to effectively spend something like £120 on their controller and thermostat which I don’t really need.
- I am not tied to Wiser and could integrate other TRVs / devices (although the Tuya based on I have been experimenting with is pretty poor)
- I can extend my current automations to do things like turn off the heating if the external doors are open, no-one is home.
- I keep a single Zigbee network and keep everything in HA
But the flip side sems to be
- I will miss out on the smart features of the Drayton app (getting up to temp at the right time rather than bog standard scheduling the heating, taking outside temperatures into consideration)
- OTA updates (It appears there is no way of doing OTA updates via Zigbee2MQTT but I guess there is very the app?)
- The app looks to automatically override / link room thermostats so the radiators are controlled by the actual room temperature not the one recorded right at the radiator
- The docs (Schneider Electric WV704R0A0902 control via MQTT | Zigbee2MQTT)suggest that sometimes commands do not get responded too and says to send them again) which would be a pain to deal with but I am guessing the app handles this
So I am struggling to decide which way to go and whether the extra cost is worth it to just install the system essentially stand alone and link to it or not.
Looking for experience of people who have Drayton Wiser kit and anything I may have missed
