I use 3 Eurotronic thermostats for a third winter season now and they still work for me. Yes. they are not perfect and have some problems - the most annoying being that the Eurotronic thermostats tend to lose the valve calibration rather quickly, but there are workarounds for this. Their performance is still like shown on these graphs: eTRV Aeotec Radiator Thermostat and Eurotronic Spirit Z-Wave Thermostats - #103 by kkossev
What were exactly the problems with Eurotronic Z-wave ?
