Have the same issue.
See my solution!
I’ve been told that there was an issue with the Tuya cloud causing this, so if it isn’t fixed for you yet make sure to restart the Tuya app and repair one device.
Since the last update on July 27th 2026 I lost connection with all Tuya devices. Restarted Homey Pro, restarted the Tuya-app,… Anyone having the same issue?
Try repairing one of the Tuya devices via the Maintenance menu in the device’s tile.
@Sunbeach: thanks ! That solved it !

All device offline. Repairing not possible. Everything does work through smartlife still.
Working again now. Don’t know what caused the issue.
All my devices went offline,
repairing does not work “pairsession_not_found”
the app on my homey was even gone after i tried to add a new device
the mobile tuya app is still working and ik can still use all devices
this is not the first time in a short time that something like this happened.
im seriously going to replace all tuya devices
ps. this is not a homey app problem, I think Tuya is prepairing to remove all external options to control devices (just like they killed the option for local tuya).
For me, I’ve never had any issues with Tuya before. It’s actually the most stable service by far (at least in my case). Do you mean that you needed to repair the device?
If they ever block the cloud method that Homey uses, I’ll just reverse engineer the Tuya mobile app since the majority of my smart devices are Tuya (WiFi and Zigbee via gateway)
I just have repaired 4 devices ( i deleted ol my old devices, because i thought it was a problem with me renaming the devices on my mobile tuya app).
the repair worked, but adding the other devices doesn’t, hangs on “getting device info from Tuya”. i rebooted everything before trying
Ps. me wanting to replace everything is also because i want everything running local,
ps, i also have tuya zigbee devices, those run locally and had no problem
Ps 2 The lights are repaired, but dont respond, timout occures
For me, repair and then restart worked. So first repair one device, and then restart Tuya app.
I’m not sure how the local Tuya protocol works since I’ve blocked almost all local communications inside my network (for security reasons), but I can imagine that they would remove an unofficial API since they already have an official cloud API that third party integrations can use for free.
Never had any issues with those either, in my case connected using a Tuya Zigbee gateway and integrated in Homey using the official Tuya app.
the local Tuya protocol doesn’t work aanymore, the blocked all possibilitie to retrieve the deviceID and LocalKey, therefor It isn’t possible to conenct the devices anymore.
I had everything Tuya in my home, but experienced lag when using devices.
I have a professional wifi mesh network and a slightly higher internetspeed than regular.
tested everything to see where the lag originated from.
conclusion, it was the time that was needed to send and retrieve the action from the cloud.
so i bought 6 Innr lightbulbs, connected them with my homey and voila, no lag at all.
but the Innr lightbulbs do not meet my requirements (i.e. no nice fading when changing colores or dimming the light). They also have a week radio, one wall in between the homey and de light, and it is offline
So i went beserk…I bought a Phillips Hue starter pack and I have to admit that it works great with so much options to configure them, and it meets all my requirements.
And yes, they are to expensive to use them all around the house. im now waiting on an Hue Essentials light pack, much cheaper, should have the same experience, but dont have the same color and dimming depth, but I don’t have a need for perfect fades or super low colors when sitting on the toilet 
I’m not sure how close you are to the Tuya server (that might make a difference) but for me Tuya (cloud) is just as fast as directly connected Zigbee devices. I recently moved my Tuya Zigbee devices to my Tuya Zigbee gateway and didn’t notice any difference in reaction time. I have fiber internet connection (200mbps download and 300Mbps upload) and use a Zyxel Nebula NWA110BE (cloud managed WiFi 7 AP) for WiFi. I also use many Philips Hue lights (and third party lights connected to Hue Bridge, I believe Innr can be added as well but I’m not sure), I barely have any issues with those either. I just wished there was a way to integrate it into Homey via cloud instead of LAN, since now I have to put the Hue bridge on my main network instead of IoT (since all local communications are blocked on my IoT network)
Ik think that my cloud is hosted in the middle east, sinds i started in the time that there where no european servers (im in europe, the Nethelands).
I have created a new account with a european server, but it didnt change a thing
I have a 1.2 Gb fiber connection, that souldn’t be the problem.
All my devices for smart home are also running in their own dedicated 2.4 Ghz network, but they are all accessible from my main wifi/network, not the other way around.
I also have a local webservice running there to be able to manage incoming and outgoing properties (like, my TV is not smart enough, ik have created something that monitors if the TV is on and saves that, homey can see the state and do things with it).
My tuya lights are wifi only, they don’t have an option to connect through zigbee.
I also added the Innr lights to the Hue bridge, 3 of them are in my bathroom and are online 98% of the time.
3 others are on the same distance, but with a wall between them and the bridge, that didnt work at all
When i replaced them with the Hue lights, problem soved. so it can only be yhat the “radio” of the Innr lights is not strong enough.
but back to the original “problem”, i rebooted everything again.
homey sees the 4 devices (lights) as online, but cant change their state. and adding the other available devices still does nothing.
guess i will try again tomorrow
Strange, I also live in the Netherlands and set up my first Tuya device in 2019, but I am on the European datacenter. There’s no lag in my case, everything is very fast and stable. What is your latency with the AWS Frankfurt region? Mine is 59 ms.
You can run a latency test here. Look for eu-central-1, that’s where Tuya’s Europe server is hosted.
Only Homey can access the Hue bridge in my main network. Direct communication between devices (local communication) is fully blocked since I just don’t want it because I don’t feel safe allowing my IoT devices to reach everything else on the IoT network. So Homey can’t reach the Tuya devices via IP, all smart devices connect using the cloud. I have a firewall rule in place to allow the Homey to reach the Hue Bridge on the main network.
aws latency is 64-67
my tuya app doesn’t let me see witch cloud server it uses, it states NL, but when i use the developer site, i cant connect because none of the selectable servers are correct.
