A deep dive into the world of smart thermostats, comparing the Sonoff Thermostatic Radiator Valve (TRV) with the Danfoss Z-Wave Valve. Discover the pros, cons, and unique features of these devices in a detailed analysis. Learn how they integrate with home automation systems like Home Assistant, their noise levels, battery life, and design. My hands-on experience and insights on which valve could be the best fit for your smart home needs.

You have mentioned Danfoss was doing something in Summer when the heating was off and you took the batteries out. I cannot find it right now, but I remember Danfoss did such thing on purpose. The main reason behind it is to do not let the valve stuck in certain position so Danfoss do cycles like open fully, close fully and back to set position. It does it on schedule like once per few weeks. It is actually good for the valve and personally I left the batteries in, so Danfoss can take care of the valve.

Hopefully you will follow up after the firmware update? If the new firmware would just reduce the valve opening after hitting the max temp it would be great. I would order bunch of these as my main criteria is the quietness of the valve.

That's the plan :)

You should test Shelly TRV 😉 BTW I like your videos 😊

The slow response is in most use cases a good feature. I think Dannfoss even claims to have a 30-minute “ventilation time”. If you open a window it will not go all open immediately. A set value change could be done without delay though. Then regarding lower temp during part of the day. In many cases it will create secondary problems in the form of energy consumption spikes. I have district heating, a “heavy” brick house and I had the Danfoss system. The monthly base rate for district heating is given by max 3hour consumption during winter months. So, when I tried the “smart” function to drop temp during part of the day, the spike it created when heating back to normal caused me to pay extra for the next 12 months. I gave the system to a friend with heat pump. He also disabled the function because the spike exceeded the capacity of the heat pump and caused it to use the emergency heating elements, hence dropping efficiency. If your gas heater has sufficient head room it might work to drop during part of the day and then take a bigger hit when heating back to normal. But as stated, use with caution.

Vaclav, I see some white blinking squares in the left and right upper corners so now and then.

Sorry for that. There is no way to re-upload the video unfortunately

I have the Danfoss Zigbee (2 years) as well as the Sonoff (one season). The Danfoss has more features, like week schedule, but I do not need those with Home Assistant.

what is the better battery consumption, to fully close/open or using calibration with external temperature sensor - then let it close/open by percentage steps automatically ? I'm using Tuya zigbee 3.0 TS0601 Thanks

@bruxy70 4 ай бұрын

That's a good question. The small adjustments might take less power, but then they will probably happen more frequently. Taken to the extreme, if it keeps adjusting constantly, that would take most power. So I guess less frequent changes would be better for batteries. But I did not measure it.

I've been using the Aqara TRV and I can say that I really like it. The display is great, it has many options in home assistant and I still have the same batteries for around a year now. When I change the temperature, it starts changing it instantly without any wait. I think the noise is the same as you recorded, it's not really bothering at all. The only louder noise that it makes for me is when it fully closes. The motor seems like it's still trying even when it shouldn't so there's a bit unpleasant sound. (Tried to calibrate it multiple times) Might be just my old valve and not a hardware problem of the TRV. Valve never fully closes during night so I don't consider this as an issue. I would buy it again. The only thing that is missing for me is the % slider. That would be a good addition.

@bruxy70 4 ай бұрын

Yes, you are right. They mentioned noise when it was fully closed, as if it did not know it is already closed. So this is consistent. For the batteries, they mentioned a much shorter time (2 months or so). They mentioned the manual setting is not smooth and jumps around, and an issue with some sort of plastic pin. So this discouraged me. Glad to see that it works for you.

@@bruxy70interesting, the battery for me is at 78% since I bought it. Not sure what could be the problem with the smooth setting nor the plastic pin.

Are you on constant heat supply or using timed heating? I hate my aqara TRV as it constantly micro adjust itself as it want heat when i have my heating off. All i want it to get to the set temp and thats it

@bruxy70 2 ай бұрын

@@lisijlisij9471 There is a program on the heating system. But I lower the TRVs pretty much consistently with the program.

@lisijlisij9471 2 ай бұрын

Yeah theres a smart schedule, but once i decide to heat up the house, i would also have to set the trv, this is annoying. Basically i want same function as analog TRVs but with wifi ability, thats all

@HansHoubraken 4 ай бұрын

How do you switch the central heating system with the sonoff TRV?

@bruxy70 4 ай бұрын

Not directly. But when the TRVs are closed, the heating water will not lose heat and the heating system will turn off. But I also have a secondary way to control it directly through a thermostat contact - I made a video about it a while ago.
