I guess then you should try. Please report back here how it worked. ---

How did it go? I used to have Danfoss zwave TRVs with Homey and that worked mostly. With the Zigbees they include and report but get messed up after a day or two if I try to control them. ---

So far, good. I havent been to my summer apartment yet, but I installed one of the TRVs at home and it seen to behave well so far… I will report further when they all are installed in the right place. ---

That’s interesting! Could be the reason. I have a 2019 also but it’s not in operation… If I ever get a response from Homey support I’ll let them know…🙄 It’s been over a month now and no response… ---

Hi. I contacted Danfoss Customer support in DK. This is their answer (Translated): _"I have spoken to our Homey and smart setup manager. He says that this issue is known, but it is not caused by our product, and therefore there is nothing we can do about it._ _He recommends that you contact Homey’s provider to have them fix the error in their product"_ :-/ ---

And for general information, here is Homeys response from today: _"We have seen this issue a few times and the cause if often another service that is also trying to control the temperature of the Danfoss Ally._ _Could you please check if you have any Flows set up with the Danfoss device? Just open the Homey app, head to Devices, long press on the Danfoss device, and select the Flow icon. Please open those Flows and take some screenshots for us to review._ _Are you using a gateway to control your ally? Has any timer or flows been programmed on the gateway that might affect the temperature set? "_ The good thing is that they are apparently looking into the issues. 🙂 ---

I have now installed the radiator devices and it seems to work ok (knock on wood!) so far. I have no flows so far and I use Homey more or less like a remote control for each device. ---

And then this response: "_Hi Thomas,_ _Thank you for your reply._ _As far as we know it isn’t possible to connect your Danfoss Ally directly with Homey. Therefor you need a gateway or something.

I am surprised about Homeys support. I explained Daphne that Ally TRV is supposed to work with Homey directly, that they do not have an API for the Danfoss gateway, that they promote the product themselves, that the have written the app and that Danfoss support is blaming Homey for the communication issues. Also I have provided Logs from the danfoss app and linked them to all the topics about the problem. All in a good and constructive tone. Here is the reply: _"Hi Thomas‍,_ _Thank you for contacting our support and reporting this issue. Our apologies for the inconvenience!_ \*I will forward your report to Development so they can take a look at it and try to fix it as soon as possible. I can’t give you any guarantees on when your issue will be found and solved, but please know that it will be placed in the right hands and will be investigated. \* _For now this is all I can do for you, which is why I’m closing your ticket._ _I wish you a great day and a lot of fun with Homey!_ _Best regards,_ _Daphne_" The _“I wish you a great day and a lot of fun with Homey!”_ is right out provoking! So Fellow Ally/Homey Victims, please help by contacting support as the need to understand that there is a problem. Frustrated! Thomas ---

Hi Peter. Are your system still working as intended? Did you not loose contact to any devices? Can you set the temperature without random results? Curious if so, and would love to hear about your setup. Thx. Thomas ---

So far, I have installed a couple of Danfoss devices at home, but from Sunday (a week ago), I have also installed 5 devices in my summer apartment and so far it works very good, I had one device jumping to another temperature just after installation, but after setting that one correct everything has worked very good. I look like the devices is slowly “learning” and the temperature is getting more and more exact. I have a HP 2019 and I have updated the FW of the Danfoss Ally devices before connecting them to Homey. ---

Thomas, I strongly suspect that Daphne is an AI. To those of you who advise switching to the Danfoss gateway: You can advise someone who is cycling into a headwind to change direction, so that they have a tailwind. By that I mean that you cannot ignore the goal. I have my Homey in the summer house. Many people use the house and therefore I have tried to simplify it as much as possible. A flow should be started a few days before arrival. A flow when you arrive at the site. And a flow that lowers everything including closing the main tap when leaving. Homey communicates with devices that have Zigbee, Z-wawe, 433Mhz, BT and WiFi. No other gateway can handle this. I firmly believe that the fault lies with Danfoss. You are welcome to prove me wrong. It is frustrating that it does not work. The worst thing is that the TRV shows the wrong value. When you get to the house, it says a completely different value than in the app. Strangely enough, it usually works the other way around. This means that the TRVs most often actually lower to the correct temperature. I have 6 Danfoss Ally directly connected to Homey Pro (Early 2023). ---

Interesting change now, after working perfekt a couple of month, all TRV have lost connection every morning. After restarting the Danfoss app, it works again, until next morning. Annoying! ---
