I also realized that my IOT Core subscription ended after 1 month. I tried to renew but that failed because the system says I already have 1 subscription and I cannot have 2. I then clicked on extend subscription. I could chose to extend for 6 months and had to complete a form that is now under review. No idea how long that will take. I could not find a way to cancel and renew my subscription to start all over.
Hola,
My IOT Core subscription is extended now, but this integration don’t work correctly.
Can you help me please?
Thanks
I have a Xaomi Smart Space Heater (Tuya-based) that is also not getting the updates so I assume it is the subscription issue or cloud-based issue. So is the solution here to use the Tuya Local Custom Integration and flash the Tasmota firmware on this?
Thankfully this custom integration here: GitHub - ollo69/ha_tuya_custom: Tuya Custom Component for testing still works and updates the states properly. Also I can force my lights to have color attribute. 
Seems like some folks discovered an issue with the Tuya SDK, testing this fix, but need to wait about a couple hours: Tuya Integration apparently fails to renew cloud access token - githubmemory

This is still very much an issue for me, tuya is not updating lovelace dashboard. I get this message in IoT tuya:
Announcement
On October 15, 2021, Tuya has adjusted some API services, allowing you to manage them conveniently. We have integrated all the basic device management and control APIs into the IoT Core Service.You only need to subscribe to one service to get the complete device management capabilities.
This adjustment involves the following cloud services: industrial general device registration, industrial general device management, industrial general device status query, industrial general device control, industrial general user management, industrial general asset management, smart home devices management, and smart home family management.
If you have subscribed to any of the above services, the platform will automatically help you subscribe to the IoT core service without affecting your normal API calls.
Then when i got to add IoT Core it says i can’t as i already subscribed to something. I can only fill in a form to extend it with max 6 months.
Seems to be resolved now, i don’t think it’s lovelace, it’s tuya integration not updating the sensors correctly (it seems to respond though when reloading the integration, so maybe it makes an exception for the first call to the cloud API).
Funny thing is it was still responding to automations, so it does seem to have to do with the device notification subscription. Whatever the case, i’ve learned some lessons here:
-Keep automations simple, try not to rely on state variables (especially when set by external cloud based integrations). I had this cool audible “lights on” thing going and the lights on automation only running when the state was set to off, but i will just remove that stuff.
I’d rather have it running again (that’s what it used to do, every time it detected motion it would turn the lights on but if lights were already on, it would tell me in the log it was already running) then saying (or doing) the wrong thing because a sensor is not updated correctly. Simply things. Also, audible alerts get tiring after a while and it freaks out people who come over :-). A automated home should serve and disappear in the background.
-I need zigbee bulbs. Can’t flash my bulbs to tasmota anymore, they all have the new chip.
I had only one lamp that suddenly had long delays when controlled from HA. I disconnected it from power and then reconnected. I think it re-registered at Tuya cloud and started to work immediately without any latency.
