Update. I have tried everything again. Removed all my devices and then re-added them. Changed all passwords again. Re-installed everything in the Tuya app. The frustrating is that my issue is adressed several times in this thread but every time it ends with “oh… suddenly it works!”.
Since I deleted all my devices the problem now is not that I can’t control them, is that I can’t add them. I still get “Please Configure the app first”.
Hi Ronny,
Thanks I will try that with scenes. Below the screenshot from the heater in homey it stays on -20.
Code Type Values
switch Boolean
"{true,false}"
temp_set Integer
{
"unit": "℃",
"min": 5,
"max": 35,
"scale": 0,
"step": 1
}
temp_current Integer
{
"unit": "℃",
"min": -20,
"max": 50,
"scale": 0,
"step": 1
}
lock Boolean
"{true,false}"
countdown_set Enum
{
"range": [
"cancel",
"1h",
"2h",
"3h",

"6h"
]
}
countdown_left Integer
{
"unit": "min",
"min": 0,
"max": 1440,
"scale": 0,

So that’s the min temperature. Seems the device doesn’t got an update from Tuya.
Hello @Sundlof,
I have the exact same issue at the moment. Yesterday I noticed the flows didn’t work correctly and I did the normal checks of restarting te app and the Homey and renter the api key.
Did you solve this already and do you know “how long” it normally takes to “solve it by its own”?
I can tell you. It takes about a week for it to solve itself because mine just started to work for no reason! 
I been at this issue for 3-4 hours the past week, tried almost everything. From one day to the other it suddenly worked without me doing anything. So, as I am happy it works right now, as all the other I can’t really tell you what I did to fix it. But here is what I did:
What I did not do:
Hello @Sundlof,
Tnx for the quick response. If I can make a good judgment call on your time line of events, I should do absolutely nothing and wait for it to start working again…….
I don’t say I don’t believe it, but when I entered all data, it worked right away…
I can’t think of one reason how something suddenly starts to work after x days ‘by doing nothing at all’ 
@Matrean, There are 2 things you can check: is your subscription expired and did you select the Device Status Notification Service.
Hi @Jurgen_Heine ,
I noticed on the tuya cloud that the IoT core is expired. Do I need to extend this? I see a monthly trial is free. but all my other devices are working properly
Yes device notification services is on
Hi @Jurgen_Heine or @RonnyW
Would it be possible to add support for the LSC smoke-detector? I recently bought some however seems this is not supported yet. The device is visible in the IoT platform but not picked up in the homey app. The connection is fine because I also added multiple LSC power plugs.
Below some information about the device, please let me know if you need more
Hi,
if this device only reports battery state, what would you assume from this device added to Homey?
You can use raw commands in flows (see description in 1st post and follow the links). Then you can trigger an alert on your smoke detector and check if Tuya sends a status which is not documented.
I was afraid that was the case, I will setup a raw info flow and test with setting off the alarm if I receive something
Tuya cloud used to work fine but suddenly stopped.
I got no errors when configuring the app but when trying to add devices, the app kept giving the message that it was not configured yet.
finally found out that Tuya IOT core on the Tuya cloud platform was expired.
After extending my subscription all worked fine again.
Hope this helps when you are experiencing the same problems.
I had the same problem. I extend my Tuya IOT core but he said ‘‘Your application for extension is being reviewed’’. How long does it take?
Seems the device is not sending anything, just tested with the smoke alarm, but no messages received on Homey. So I guess there’s no way to get the alarm data from this device directly. I did receive a report on the tuya platform log:
I now tried an alternative which did not work well quite yet. I’ve added a virtual device, tried many different ones and then switch once the smoke alarm goes on, This device I can then add into homey to have a single pane of glass for everything.
Now I run into the problem that the device state of the virtual device does not change(on/off) in Homey when changed from the Tuya app. Anyone any experience with those virtual devices, are there any that do work/sync state?
Thanks!
Maarten
Took about 12 hours, you won’t get any confirmation by mail.
Don’t forget to save the configuration in the app and restart it again.
You have to set the state of a virtua device via flow. But if you don’t get a davice state on alarm, you have no chance to do anything in Homey.
I tried adding a virtual device in Tuya. Then I created a scene in tuya to switch that virtual device to on once the alarm goes off. The smoke alarm is visible in the tuya app. This all works fine.
The virtual tuya devices is synced to homey.
However when the virtual device is switched to on in the tuya app this state is not reported to homey somehow.
It works! In a few hours it’s approverd and i can add the Tuya Cloud devices in Homey, Thnx.
Ok, but what about in 6 months from now when the extension is over?
Should I stop buying Tuya based devices if I want to use it with Homey?
