I’m using a raspberry pi with a ‘sonoff universal zigbee 3.0 USB dongle’. But I’ve no clue what I’m doing. I originally got into it just so I could automate a bedroom light for the wife. Beyond that I’ve got a couple of lights and contact sensors and the recent attempt at controlling a dehumidifier. Googling and blind luck has got me this far.
I wonder if it helps that the door contact sensor is in the same room as the zigbee dongle? Maybe 20ft away
So, a half remembered Radiolab episode or maybe it was 99% Invisible talked about this. If I remember rightly they did consider changing it because it was so much quicker and easier typing in English and Chinese character set takes up a lot of storage which was a big deal in early computers. Until someone figured they could break down all the Chinese characters into a much smaller selection of base shapes. So you could make a character by pressing a small selection of keys. So it meant a much more manageable keyboard. I think it’s even resulted in quick Chinese typists being faster than English ones.
