Aqara temperature and humidity sensor T1 driver issue

Hi Guys,

I needed to buy som new humidity sensors and bought two Aqara temperature and humidity sensors as I have these since before and they work well. I noticed that there where two versions sold of which one was slightly more expensive. Without doing any analysis I assumed the slightly more expensive one was the latest verision and bought two of those. This seems to have been a mistake and slightly confusing one at that.

The sensors I have since before are called 'Aqara temperature and humidity sensor' with model no WSDCGQ11LM. There is a driver for these that works swell.

The two new sensors I bought are called 'Aqara temperature and humidity sensor T1'. The Aqara model no for this sensor is TH-S02D according to the Aqara website. When connected to Hubitat they how ever show up with the model no RTCGQ01LM. This sensor, the T1 version, does not work with the WSDCGQ11LM driver. Searching here on the Hubitat forum, RTCGQ01LM shows up as both a motion sensor and a humidity sensor. This seems odd as they probably won't have the same sets of parameters? At any rate, nor the driver for the humidity version or the motion version works with the T1.

Anyone else come across this issue? Is there a driver that works for the T1 version?

I suppose you have this device :

Its Zigbee model Id is lumi.sensor_ht.agl02

Have you tried manually assigning the HE inbuilt Generic Zigbee Temperature/Humidity Sensr driver?

After manually changing the driver, obligatory pair the sensor once again to the HE hub (without deleting it!)

I expect the temperature and the humidity reporting to work. What may not work is the battery reporting.

Hi kkossev,

Thanks for your reply.

Yes! That is the one. It appears like this when connected.

As far as I can see there is one generic driver for temperature and another one for humidity, but I gave it a try but none of them seemd to work. I did a reset on the device and the hub found them again, but no change unfortunately.

It looks like they appear as 'unknown' in the network map. (Because they don't have driver?)

No, it is not required to have a specific driver for a Zigbee device to be visible with its name/label on the map. It seems to me that the pairing process does not complete successfully.

With the HE inbuilt Device driver, do you see anything in the live logs when you press the sensor button shortly? If not, try removing and re-inserting the battery again, Anything in the logs?

@magnus.s yiu can try the "Zigbee - Xiaomi/Aqara Temperature & Humidity Sensor (w/ healthStatus) " mod of Markus's driver :

https://raw.githubusercontent.com/kkossev/hubitat-Markus-Li-fork/release/drivers/expanded/zigbee-xiaomi-aqara-temperature-humidity-expanded.groovy

First - install the driver manually. Next - remove the WSDCGQ12LM and pair it again as a new device.

It worked! Big thank you @kkossev ! :slightly_smiling_face:

No, celebrated to soon, didn't work :slightly_smiling_face: But thank you anyway. I think I will just replcae these. The connected fine and was recogniced imediately, but then goes scilent. Thank you anyway for your help!

I can confirm the problem - because of some reason, the sensor does not send periodic check-in messages and does not update the T/H frequently enough, so the healthStatus goes offline :

I will not give up and will try to make it work reliably with HE, but it will take more time.

This Aqara T1 Temperature and Humidity sensor does not send updates frequently enough, even when paired to Aqara E1 hub .. :frowning:


There are no settings in the Aqara Home app to configure the reporting interval or the thresholds.

Update: this sensor seems to be reporting on 0.5 deg.C delta, so generally, it is not so bad!
