Thanks for the JSON file @jmarandet !

I do indeed see some Matter clusters not managed by Gladys:

```auto
"id": "156",
"name": "PowerTopology",

```

```auto
"id": "144",
"name": "ElectricalPowerMeasurement",

```

```auto
"id": "145",
"name": "ElectricalEnergyMeasurement",

```

I’ve created a feature request to keep track of your request:

> [@\[Matter\] Ajouter la consommation électrique d'un appareil](https://community.gladysassistant.com/t/matter-ajouter-la-consommation-electrique-dun-appareil/9783):

> Suite à la demande de @jmarandet pour gérer ses Shelly ( [Aide pour connexion Shelly EM avec Gladys en MQTT - #8 par jmarandet](https://community.gladysassistant.com/t/aide-pour-connexion-shelly-em-avec-gladys-en-mqtt/9741/8) ), ajouter la gestion de la consommation électrique et des clusters Matter suivant : "id": "156", "name": "PowerTopology", "id": "144", "name": "ElectricalPowerMeasurement", "id": "145", "name": "ElectricalEnergyMeasurement",

Even before talking about Gladys, I think you need to make sure everything works on the Shelly side.

Have you tried on your computer software like [MQTTX](https://mqttx.app/) that let you view the messages published to an MQTT broker?

The first step to get unstuck is to see where your Shelly is publishing!
