Hello everyone, i tried this week to pair the brand new meross MSS315 matter plug, and it’s not working, I end up with this error all the times : ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/6/6/66868c3d48e480d615e2e6730b5624bed57e7e71.png) I tried the pairing process from the homey app, it recognizes the device nearby, ask me to choose a name, tell me “devices” added to home and then this error. The device is pairing correctly to HomeKit, then I tried to generate a paircode directly from homekit to link the plug to homey this way. Same issue, not working at the end of the process. My homey is only connected with ethernet and I saw the plug is WIFI based protocol (not thread) Do you have any ideas ? See ya Alexis ---

I dont see support for this device in the Meros app. So you should ask the developer to add this device(if possible) ---

Thank you for the answers. @Ria_Banis this is a matter device so it don’t rely on the apps. @robertklep the fact is i tried both ways : 1. Homey → Meross by scanning the matter QR code from the Homey IOS App 2. HomeKit → Homey → Meross Plug by scanning the matter QR code from the homekit app and clic on the plug device to get the matter pairing code, then go to HomeyIOS App to add new matter device and tap the code i just get from HomeKit From homekit directly i can control the plug, but it never add in the Homey IOS App ---

Please have a look at this [post](https://community.homey.app/t/matter-und-thread-hilfe-und-tests-fur-den-anfang/84178/22) (German language). After an update of the Meross plug he was able to connect it over Matter with Homey. ---

Ty for the reply, i checked out this comment : > Kurze Rückmeldung: > Meross hat ein Firmware-Update für den MSS315 veröffentlich. In Version 9.5.33 wird ein Bug mit dem Matter-Binding behoben. Danach konnte ich die Steckdose mit Homey verbinden und kann diese jetzt An-/Ausschalten. In Meross App, my plug is marked as up-to-date with **9.5.31** version number ---

I don’t use any Meross devices, so I don’t know if there is something like an experimental firmware available like it’s by Homey the case. Maybe ask the post writer for help. ---

Hi @AlexisC , I checked it in my merls app. It’s 9.5.33 for hardware version 9.0.0. With 9.5.31 the matter pairing process won’t succeed. Maybe you know about this website? There are some hints to get it working: > **[Matter Smart Plug with Energy Monitor](https://www.meross.com/en-gc/smart-plug/matter-smart-plug/159)** > > Meross Matter smart plug MSS315, compact mini size. With Matter integration, the device can support all major platforms, like Apple Home, Google Home, Amazon Alexa, Samsung SmartThings, and so on. Greetings, David ---

thank you for your answer and the link. I followed the steps but, no firmware update avalaible in my meross App, still in 9.5.31 ☹ ---

I was able to pair it with Homey Pro early 2023 using Matter (without the Meross App for Homey). Firmware of my MSS315 is **9.5.33**. Unfortunately, there is no report of any energy consumption. Similar to what I’m experiencing with SmartThings. I contacted Meross support and waiting for their response in order to know if I should return them or not. On a side note, I was unable to pair my MSS315 to Homey using the multi-admin feature after I connected it to SmartThings and used the shared code. ---

To pair them with Homey via Matter, ensure they are updated with the latest firmware, as earlier versions had a bug. Initially, pair the plugs using the Meross App, perform the firmware update, and then proceed to pair them with Homey. Regarding power measurement, the Matter standard did not support this feature until version 1.3. The Meross plug does not utilize the Matter specification for monitoring power; instead, it runs a local HTTP server to manage this function. It remains uncertain whether future firmware updates will change how this works. ---

I’ve now firmware 9.5.39, but there is no new matter version yet (later than 1.3). But I want to be updated when there is. ---

No, because Homey uses still Matter v1.2. To find out when the Homey firmware will support Matter version v1.3, you can follow the [changelog](https://homey.app/en-us/wiki/homey-pro-early-2023-firmware-changelog/).
