There's dozens of vendors selling these, they were very useful for automating things around the office in a job I had, for example they set it up to turn the lights on at the start of the day, to turn the aircon on, to open the entrance door when any of the workers did something on the phone (IIRC send a Slack message? or maybe we had an app, don't remember TBH), to automatically lock the door (with a "turning" one). I've thought of buying one to be able to leave my key at home, but kinda scared of them going wrong and being stuck out.
