Zigbee2MQTT

• [ ] (older devices) You have ensured legacy is off/false for the device in the Z2M devices Settings (specific) page and that your actions matches those with legacy off?

Switch does have a "hold (released)" for top and bottom button, but both trigger the same ZHA event, so cannot be reliably mapped.

Image needs to be cropped properly

It has been cropped properly. That nub at the top is part of the product: https://www.ikea.com/us/en/p/rodret-wireless-dimmer-power-switch-smart-white-80559800/

Not sure what the nub at top has to do with cropping properly, as stated in the "rules" for a PR, it needs to be cropped to the device edges. The x/sides are no where near the device and the top and bottom still has padding from the device

There is also a nice image and blueprint for this device in the repo using Zigbee2MQTT (zigbee2mqtt-ikea-e2201). I would suggest ussing those resources and convert for ZHA
