6 hours late to the party but just giving thought to other devices.
I have the spirit TRV working well, although I cannot report on battery length as its only a couple of weeks old.

Not badly priced I suppose.
Assuming this is the one of course.

How noisey are they? I heard one guy saying they were too noisey for him.
But they do look nice 
And good reviews on functionality

I've just ordered one from Amazon - price is pretty much the same for one as ordering from Reichelt because of the £8.95 delivery charge. That delivery cost seems to be the same regardless of how many you order though unless you want 39 of them which makes the weight over 10kg and shipping cost leaps to a massive £13.49 
If I end up getting more then I'll get them from Reichelt, unless anyone finds them cheaper elsewhere.

I think it was quieter than the Salus one just tried. I cant hear it very well, sometimes I have to put a hand on it to see if its doing something I just commanded. I imagine you can hear anything in a dead quiet room.
I think sometimes it depends on the pin and metal work on the rads, is it possible some configurations can amplify the sound?

Thank you Sir, I may have to take a look at one of these too
Spirits get noisy when they turn from fully open to fully closed (or the other way round). They do it in around 1 second so the motor is spinning fast. Little adjustments are much quieter. IMHO
For the Danfoss LC-13 - I have never heard them make any noise.

Finally managed to get my Spirit installed and working - I had to use the RA adapter, but made the mistake of fitting the nut and bolt first, it wouldn't push far enough down onto the valve. I'll know better for the next one.
Seems to work nicely with @Ultrasmart.pl' driver (thanks Mario). Early days yet, but I think I'll almost certainly buy some more.
Good you've got the Spirit
BTW these TRVs work with Generic Z-Wave Driver and the driver isn't mine but Hubitat's.

Hi,
Would you mind sharing the driver you are using for Danfoss TVR, I have use the one as described in the thread Community Device Drivers (FKA Compatible Devices Wiki) however it is not working for me.
Is this the same you have used and have you changed anything in the code to get it working?
Many thanks,
Keith
Doesn't it work at all or you just can't change a wake up time?
It does not seem to work at all for me.
Either directly from the device driver options or from the tiles I added per TVR in the dashboard.
When I change the temperature set point, it does not transfer to the device. Also when setting the option to turn off a device it does not set it back to 4 degrees, which is what I understand it should do 
When I execute commands from the device driver, I can see the corresponding results on the right side of the driver page, but the TVR does not react and change as per my choices
Sure, here you go. Although I don’t think there’s much difference between the two. I just added better logging for my needs.
Thank you, I will give this a try in the morning

There's a 30 minutes wake up time in the driver you tried. So if you change settings on the device's page the TRV will not read them instantly - it will depend where in 30 minutes cycle it is at the moment of change.
Guys, have you managed to controll Danfoss LC-13 using Google Home?
Does this work with google home?
I'm not sure I'm afraid, I'm an Alexa person
