Tuya Power Sensor Latency

[pwhitea]

The problem

I have noticed that the readings from a number of sensors that I use for power monitoring in the energy dashboard are inacurate since 2023.12.1 release. I am comparing the sensor value from the Tuya integration with the value in the Smart Life app and see there is a considerable refresh latency occurring. When I compare my energy dashboard prior to Dec 2023 to historic data in the Smart Life app there were slight variances (5-10%) but generally cumulative daily values were comparable, now my enegy dashbaord readings are C 10x lower than cumulative values in smart life. Initially I thought that I had a problem with Riemann Sum's but following investigation its the actual sensor values being provided by the Tuya integration.

If I compare real time between a HA sensor and Smart Life app there is a discrepancy for all smart plug devices I have (10 in total) at any point in time. Close comparison of the HA power sensor and smart life real time power reading shows that the only time the two are comparible is after the integration has been reloaded, they then remain comparible for C10 minutes before the latency appears again. It appears that the appliance attached to the smart plug (in this case a TV) varies its power consumption - smart life captures this but HA does not.

Hey there @tuya, @zlinoliver, @frenck, mind taking a look at this issue as it has been labeled with an integration (tuya) you are listed as a code owner for? Thanks!

Here is a further example of the problem. In this case the Tuya plug is on a washing mashine, in this case the washer is running thus as you can see in the Smart Life app there are ongoing changes to power consumption yet in HA there has been no update come through for 6 minutes. While I realise there will always be some missed updates what I am seeing is that in HA sensor values are in some cases not updating for 30 minutes. Updates seem to be be better for the first 30-60 minutes after restarting the Tuya integration but then I see the problem in this video.

suspect its the cloud connection failing - see https://github.com/home-assistant/core/issues/115344

[niltonvasques]

Same issue here! In my case, updates in my case is taking 5~30 minutes.

@niltonvasques thats exactly what I am seeing, after a restart senors update frequently, but after 10 minutes I get 30 min + delays on sensor updates when I can see changes on Smart Life.

@jonwaland have checked the logs/run debug and I am seeing no errors on my installation

I often dont get errors - even with Debug. What I get is "misses":

but 2024-04-10 17:24:43.365 DEBUG (SyncWorker_32) and 2024-04-10 17:25:13.867 DEBUG (SyncWorker_34) didn't receive an update. meaning HA was out of sync with reality...

If you enable debug, I suspect you will see regular "Received update" messages, but with gaps...

[pwhitea]

Same here, I am getting no errors and the debug shows nothing. The only way of re-creating the problem I am seeing is to physically compare the Smart Life app with the data hitting Home Assistant.

Hey @tuya, @zlinoliver, @frenck, any updates on this one?

Mindful that this issue has been present for some time assuming that it relates to Tuya cloud services and not an easy fix. With that in mind just bought 4 TP-Link P110 plugs and can report that they work perfectly - consumption reported by HA / App the same. Appreciate an update as if this is going to be a lengthy fix will buy more TP-Link devides and get my Tuya ones listed on Ebay!

[niltonvasques]

Some smartplug devices I could fix by connecting them to HA via tuya local (https://github.com/make-all/tuya-local/issues/420#issuecomment-1435765676), but not for all of them.

[juanmijm]

same here, I have 2 smarts plugs updating sensors every long long time, before it had the unofficial LAN integration with those same plugs and it updated very quickly.

The strange thing is I have others tuya devices updating every 5 seconds, with this same integration, Is there anything I can do? I think it was a mistake to switch to the official integration...
