I have a ZHA and also Z-Wave network set up, so I am deciding which route to go for smart TRVs.
I have also looked into Tado, but found some posts that these are not that “smart” meaning, they either fully open or fully close the valve, instead of doing it gradually.
I searched through forums and found out 2 candidates.
Either Aeotec Z-Wave Plus TRV https://aeotec.com/z-wave-home-automation/thermostat-radiator-valve-trv/ (which is probably just rebranded Eurotronics with maybe newer firmware).
-States that it does gradually opening/closing valves.
And for Zigbee - Zigbee 3.0 certified Danfoss Ally https://zigbeealliance.org/zigbee_products/danfoss-ally-radiator-thermostat/
Basically I want something that does not blast open the valve, overshoots the temperature, then closes it and repeat it again. As thats gonna be noisy and not that comfortable. (I head it stated, that tado and some valves do this.)
What about battery? Has anyone experience if there is difference between Z-Wave, Zigbee TRVs in battery life?
What would you recommend, if you have experiences in both of these protocols?
Have a nice day!
