How can Homey claim most other people do not have that issue? AFAIK customer support mostly hear from people who have issues - and nothing from people who don’t, so they have no clue how many use Homey together with Ally thermostats. This setup was the primary reason I sent out and bought a Homey and so far it has been a complete waste of money 
Automatic turning off heat when windows are opened (sudden temperature drop) is one of the nice things about the Ally thermostats. They turn off for approx 10min I believe when they detect a temp. drop.
I had tried on and off for the last 12 months to get Danfoss Ally to work with HP23.
I experience the same things as everyone else. I have had a correspondence with Homey support. They cannot replicate my issue with and exact copy of my flow - they say..
I also contacted Danfoss . Not much help.
How hard can it be to fix ?
That’s what they say to eveyone that have problems with Ally. They can’t reproduce or the problem is on Danfoss side etc etc.
The funny thing is - I paired the Ally TRV’s to an older Smartthings hub and they have worked smoothly without a single problem for 8 months now. So the question is - how is it possible the same TRV works with Smartthings reliably, but fails miserably with Homey Pro?
Just a random thought: the chip that Homey uses to support both Zigbee and Thread uses so-called “multiprotocol” firmware that the rest of the world has stopped using because of all the issues (in terms of stability and connection quality) that it caused.
Oh that would be a bummer. Not that easy to change the chip afterwards. But that would then kind of explain why Homey doesn’t “find the issue” if the truth is this and they just don’t want to admit it.
The issue is also that for some people it works great while others have nothing but problems. Without access to logfiles or more information, there’s nothing much you can do. That’s why some people have started using better other Zigbee solutions, like zigbee2mqtt.
Oh do you mean they have another “bridge” like Raspberry Pi and then control the Zigbee devices through that with zigbee2mqtt?
Yes, as a workaround for Homey’s suboptimal Zigbee implementation.
