Something wrong with my Device Type

Devices & Integrations Connected Things

Hi community,

I’m creating a new device type and something goes wrong, my device is a ZigBee falls sensor. I don´t know if it is well implemented but for now in the part of “Tiles” something must be wrong because the icon which appear is unknown and doesn´t change color when i simulte from active to inactive . What else is good?

Thanks
