Not quite correct. Apps can implement Matter devices, but their main function is to make the device discoverable via the Homey App Store. For example, the Eve App for Homey only includes Matter devices, and its purpose is to ensure everything is easily accessible for the end user. 
However, an app doesnāt need to support the device via Matter for it to work with Homey. You can simply select āMatterā when adding a new device to Homey.
Abe,
Thanks for elaborating; this is new to me, and I really think this crucial detailed info needs to be added to the app store and knowledge base.
Up 'till now I thought Iāve read somewhere a Matter device doesnāt need an app, only if the developer wants to implement custom capabilities (if thatās true at all).
When I search for Matter apps, it shows 4 apps, but it also mentions you donāt need an app? Very confusing for many users imho.
So apps cannot implement device support, they can only add metadata. If Homeyās Matter implementation is missing features, an app cannot implement them, like they can with Zigbee or Z-Wave.
Hi @TedTolboom ,
would it be possible to adjust battery level monitoring for lumi.sensor_ht.agl02 ?
Seems itās way too much dependent on outside temperature, eg. compared to lumi.weather (on graph placed on same location) and Iām getting false battery warning and itās also not possible to adjust battery warning level for those sensors.
Thank you.
Hello, I recently bought a cube t1 pro and a lightsensor t1. Both have problems connecting to homey pro. Sometimes the cube gets connected but does not give any response in Homey. I want to use these devices in the livingroom where 11 Ikea zigbee lights en two Hue lights are connected to Homey as zigbee routers. The latest versions of the Aqara app and Homey pro are installed. Has someone an idea what I am doing wrong or I am missing?
When will the new Aqara smoke detector be added to the device list? (lumi.sensor_smoke.acn03)
Hi @TedTolboom. Iāve noticed a few issues with the Smart Radiator Thermostat E1:

Hello and thank you for all the support you provide. Do you know when you will be able to develop the correct drivers for the Aqara Ceiling light T1M?
some of my lights and fans got switched off when my app was auto updatedā¦ is this normal? Nice to see some of my devices suddenly working again after the recent updates though. Also good to see the H1 triple (non-neutral) supported now. Fingers crossed for the H1 triple (neutral) to be supported next 
Iām absolutely lost here. Iāve been trying to fix the connection with my Aqara devices for weeks now with no results. Iāve been reading through this thread for days. Iām simply unable to connect all of the devices (listed in the screenshot above) using the traditional adding process. The strange thing is that Iāve successfully added these devices in the past. The only device that I was able to reconnect is the P1 sensor.
Today, I purchased a new Homey Pro, hoping it would fix the problem. But the issue remains. Even the devices that were connected to my old Homey are now unable to connect. These worked until today, but now I am unable to restore the connection.
Can someone guide me on where to start to debug this issue? Are there some quick checks I can run to determine where to look for the problem? The devices that are unable to connect are:
All the above devices have once been successfully connected to the Homey in the past.
Did you restore a backup from your previous Homey? If so, you probably want to do a full Zigbee network reset on your new Homey (here: Homey Developer Tools).
Yes, I restored a backup of the old homey. Just tried to reset the Zigbee network. After that I was able to connect two devices (1x Motion Sensor + 1x Wireless Mini Switch). But it seems like Iām unable to connect more of them.
Because?
Also, all your devices you mentioned seem to be end devices. You really want to have router devices in a Zigbee network, about 1 router device on 5 end devices.
And also assume that Zigbeeās range is at most about 5 meters, which is another reason why you want router devices (so you can increase the range of your network).
Thanks for your reply! Iām not sure why the devices arenāt able to connect. It start the adding flow, the device blinks tree times and nothing happens for a while. No errors. Iām very close to the Homey at that moment. Could it be that are too many end devices present that that this will overload the connect process?
Adding a Zigbee router seems like a good idea. Can I use an Aqara hub? I read some use the old one from IKEA. Which hub works good with the Aqara app that you know of?
Youāre pairing one device at a time, so that shouldnāt be an issue. Try moving the device a bit away from Homey, like 50 to 100cm.
An Aqara hub isnāt a router, itās a controller (like Homey is), thatās something very different. Zigbee routers are usually devices that are permanently powered, like smart plugs or lights.
Please add support for presence sensor fp1e
Did you bother to read the first post?
Iāve it installed on my homey, works perfectly.
YES, āAny requests please post them in the Xiaomi / Aqara Zigbee topic on the Athom Community forum or contact me on [Slack ]ā. So i did 
what else to do ?
I got everything working again after reinstalling some IKEA Tradfri lights around the house. The lack of routers that youāve addressed seemed to be the issue. Iām very happy everything is working again. Many thanks for your help!
