Danfoss Ally - devices stop responding

Hi,
I have the Homey Pro 2023 and added 7 Danfoss Ally to the Hub (directly using the Homey Danfoss App).
Devices are detected and I can adjust the temperature directly and create flows that sets the temperature without any issues - for the first couple of hours.
Then, they start to become unresponsive and I get timeout errors if I try to set them directly from Homey.

Is this bugged?

Btw, I have the Danfoss Hub - but it’s not connected - the Ally Temperature devices are connected directly to Homey.

Br,
Kralle

Please provide for some relevant info, and
product links and such.
Wifi? Zigbee? Zwave? Bluetooth?

:rofl: Excuse me? Do I know you? This is your first post, and you start bossing me around? You don’t tell me what to do, funny guy.

And when the TS doesn’t respond in 2 months,

the issue was not an issue at all appearantly, so the process ends here…

I have the exact same problem. I have 7 Danfoss Ally thermostats, a single zigbee relay (for powering on/off LED spots) and an Airthing View device connected to my newly bought Homey Pro 2023. Everything worked great - for a couple of days.
Now, if I reset a thermostat it is impossible to get it to connect to the Homey, and if I try to change a temperature for one of the thermostats that are still connected, the homey app times out after 30s - but sometimes eventually reports ok. However, it takes like 10 minutes for the thermostat displays to update - and the temperature being set is complete wrong. I tried to set all to eg 21 Celsius but some changed to 33 Celsius, others didn’t change.
I have tried placing the homey next to a thermostat when reconnecting and adjusting - but that didn’t make any difference.
I have filed a report in the Danfoss Ally app (version 2.3.1) : aa37e5e6-a7ee-41d0-b146-c2d0f2618b47

I filed a support issue instead, and the case was handed over to development.
Using my debug files etc, they could establish the same evidence, as you described it as well.
Nothing has yet happened, so in the meantime I had to put the thermostats back to the native Danfoss hub.
It’s just a shame, since they worked perfectly in SmartThings, but never worked in Homey (for me)

I have the same.
So the situation is thar Ally does not work with Homey.?
Can Homey confirm.?

I have exactly the same problem. I made a routine that checked if the set value was correct every 30 seconds. it can take up to 10 adjustments before the set value is correct

Has this issue been solved now? I am considering Danfoss for my under floor heating system with Homey. But if it does not work I would rather look for something else.

I have two Homey Pro (Early 2023) in different buildings

  • one with two Danfoss Alley and
  • one with three Danfoss Alley

As long as they react, they sometimes set wrong temperature.
For example:
Flow sets 22°C Danfoss Alley goes to 28°C.
Flow sets 17°C Danfoss Alley goes to 12°C.

Latest after some days they stop working completely.
Homey shows the setting that the flow set, but the Danfoss Ally does not change its temperature.

It is completely unreliable.

It is the Ally Radiator Thermostats you are using right? Not the Icon2 wall thermostats connected to Ally Gateway ?

It is the Ally thermostat without any other Danfoss hardware.
Ally is diretcly connected to Homey.

Homey still doesn’t work. I opened a support case, and was in dialogue with the Team at Homey. They closed the issue and told me they’d transfer the issue to the App Team, and since then… nothing.
I chose to use the hub from Danfoss, but I would prefer the Homey over anything else.
Disappointed that it still doesn’t work.

I have the same issue and I did contact the Homey support about it back in December. The answer I got was more or less nothing. They don’t care. The other issue I have is that the measured temperatures do get stuck after a couple of days. It happens for all my 9 Ally thermostats.

It worked absolutely fine when they were connected to SmartThings. I might go fully back to SmartThings and put my Homey hub up for sale.

I have the same problem and even though I told them I was not the only one with the problem the answer was that they could see that most people did not have this problem so they could not do any more about this issue, but I could send a device to them to investigate. So I dont expect them to try to solve it. It is an arrogant behaviour from them.

Hi, I am about to upgrade the floorheating and get Danfoss Icon2.

I do not have Homey Pro yet.

Can I use Homey Pro to communiate with Danfoss Icon2 or should I get Danfoss Ally gateway?

Best regards

As you can see from my earlier comments I have the same issue, but you are saying it works perfectly with the Danfoss gateway so we are sure the issue is with the Homey app and not the thermostats?

I think the faults can be traced to Danfoss. They have provided Athom with information so that the thermostat can be integrated, but they have withheld information that prevents the service from working smoothly. Could it be that they want it to work poorly, while their gateway works perfectly? Maybe I have misunderstood the problem completely. I have bought six thermostats and spent a lot of time on this. How to fix the problem. Purely hypothetically, do you in the forum think that a class action lawsuit would work?

Where did you get that information?

Zigbee devices that stop responding is, sadly, a common issue with Homey. Not just with Danfoss, but across all brands (search the forum). Also, the OP states that they worked well with SmartThings, but not with Homey.

OK, I’m new to this and I’m probably wrong. It’s just strange that everything else works except Danfoss. I have apps from Danfoss, Develco, IKEA Trådfri, Mill Heating, Nexa, Qubino, SONOFF, Telldus, Tuya, VThermo and Wireless Weather Sensors.
Anyone have suggestions for thermostats that work with Homey?
