High accuracy Aqara detector RTCGQ13LM

Configuration Zigbee
1

Hello to all,
New in the world of Home Assistant, I am in the process of migrating my home automation from Jeedom to Home Assistant.

I’m slowly getting used to it, even if I’m far from having done the trick yet.

But I have a problem with a sensor I just received, it is the Aqara High Precision RTCGQ13LM.

I am using ZHA with a Conbee II, and unfortunately it is not recognized correctly.

I don’t have the battery level going back up (not too bad) but I don’t have the motion detection going back up… that’s annoying.

Is there a solution? Do I have to install in // Zigbee2MQTT where it seems to be supported? Can the 2 systems cohabit?

Thanks in advance for your help and advice.

Nice day to all.

Seems this sensor isn’t supported in ZHA, maybe it would be a good choice to switch to Zigbee2MQTT (which in my opinion is the better choice).
ZHA and Z2M can coexist but not with the same Conbee II Stick, you would need in this case a second stick. Both of them cannot access the same Zigbee Stick at one time.
But why not switch completely to Z2M? Once setupped it works flawlessly and new devices are often first supported by Z2M and sometimes it offers more than ZHA. For example the aqara vibration sensor, it’s tilt angles are only submitted by Z2M but not ZHA.

Hi @madface,

Thank you for your answer.

I went with the solution that seemed simpler, but I am not against migrating to Z2M, but I have more than 30 devices, I have to synchronize them again?

I have several Conbee II keys, I could possibly make the 2 cohabit if I understand well.

Thanks for your help and advice.

In my case i had to synchronize alle my devices again as i switched over to Z2M, yes. As i have also about 30 devices it were 2 to 3 hours, but i used it to sort them again and did a different naming schema.
But if you have several keys, just try it with a second one, give the right port for the new one in Z2M and there you go.
Just a little hint, when you start set the legacy options to false in the config:

  legacy_entity_attributes: false
  legacy_triggers: false

First one will save space for your database in future and has no disadvantages (in my opinion this should be the standard setting for HA). Second one will be standard in the future, why not start with it…

Thank you for your answer and for your help.

According to you, Z2M will replace ZHA?

Thanks again.

Only if you want it to. Both can run side by side, but they are two separate zigbee networks. ZHA/Z2M devices won’t bind with, route through, or otherwise communicate via zigbee with Z2M/ZHA devices. It is generally considered best to choose one and build out the strongest mesh possible.

If you already have a spare stick, it is definitely worth checking zigbee2mqtt out. You can try a few devices out and migrate at your leisure if you so choose.

But…

No one has suggested trying to get the device added to ZHA. My experience has been ZHA devs are helpful in trying to add support. Open an issue at Issues · zigpy/zha-device-handlers · GitHub.

You can do it without repairing:

Thanks for your answer, I agree with you, it is better to strengthen the network and have one system.

So I am thinking of migrating to Z2M.

Thanks again for your help.

Nice evening

Great, thank you so much for your answer.

If I can avoid re-pairing everything, I’ll be fine.

I will set up Z2M and try to migrate.

Thanks again.

Do what? Migrate ZHA to Z2M? I don’t think so, but would be happy to be wrong.

The linked video only references changing coordinators for an existing ZHA install. No mention of zigbee2mqtt at all.

Much, if not most, of the network and device data is actually in the on-disk databases and I know of no way to migrate that between the two platforms.

It’s easy to try without breaking anything if you already have a spare coordinator stick. ZHA and Z2M can coexist side by side.

You are right, sorry for the confusion. It is only possible to change the hardware on the same software base.

I would as well recommend using Z2M in parallel. I had other devices not work as good on ZHA, so having the option is definitely good. If you find the time later, you can always connect all your devices to Z2M.
