Heating season has started again for a few weeks now, so another update, in case a lost soul ends up here. Would be cool if we get some reviews of other TRVs in here, ideally from people who also tried different ones and can give pros and cons.
BRT-100-TRV
As mentioned in my last post, I was going to update the coordinator firmware, and finally did so during the summer. So far, that seemingly solved the issue where they stopped accepting commands, but then again I’m only using two of them now, in places where I never adjust the temp anyways, since touch controls suck a**. I might as well have been an interaction if manual vs. remote control.
The only minor issue I still have is that somtimes when you change the target temperature via zigbee, the device acknowledges the change, but nothing happens for up to ~5 minutes. So I can either wait 5 minutes, or touch any of the controls to wake the TRV up, in which case it displays the new target temp after half a second or so and starts opening/closing the valve. This is slightly annoying with time-critical automations. For weekends I wanted it so that the kitchen gets warm as soon as someone gets up (motion detector in bedrooms), but if you add a 5 minute delay you might end up in a cold kitchen even if you visit the bathroom first. 
I’d say it happens one out of 10 times.
TV01-ZB
Also in a room where I almost never adjust the temp (guest room), but it’s nice that is has real buttons, so if you have someone over you can just tell them “press this button to raise temp” and they’ll handle it just fine even if its half dark.
Downside: Can’t get the schedule to work. Fiddled around for days. Time is set correctly on device, schedule is displayed correctly on device, device is set to “auto” mode, yet it stays at one temp the whole time. So now I do the scheduling via HA.
Sonoff TRVZB
Has become my favorite so far, even replaced a BRT/Moes one with a second Sonoff. It looks sleek, the dial makes it quick to use, the display is minimalist but fine for my needs. Never had any networking or responsiveness issues.
I never encountered the battery drain issue again with either one, and with a recent firmware update, it became possible to configure how much the valve opens, so I can finally have the temp increase gently if I want to.
