Ikea shortcut button e1812


I have integrated an Ikea shortcut button e1812 with zigbee2mqtt, which works so far. Only now I’m looking for a possibility so that with 1 x press a device is switched. I search now already 3 days in the Internet only find nothing functioning, a Blueprint I found (https://github.com/EPMatt/awesome-ha-blueprints/blob/ab6d6bd0f42c796293575bc7f1422bf833ce106c/blueprints/controllers/ikea_e1812/ikea_e1812.yaml) only I do not get this simply at the run.

Does anyone know a simple automation, or has a tip for me?

With ZHA de button does not work for me.
