Read/write Clipsal smart switches
View notes.md

This is notes for anyone who is interacting with (in Australia at least) Clipsal-branded smart switches that operate over BLE. (They also come with a ZigBee certification document, but it seems like it was never enabled.)

They have a couple of interesting UUIDs (these are here for y'all searching for them):

  • Control service, 720a9080-9c7d-11e5-a7e3-0002a5d5c51b

    • State characteristic (i.e., switch on/off), 720a9081-9c7d-11e5-a7e3-0002a5d5c51b
    • Level characteristic (i.e., brightness), 720a9082-9c7d-11e5-a7e3-0002a5d5c51b
  • Command service, 720a7080-9c7d-11e5-a7e3-0002a5d5c51b

    • Request characteristic, 720a7081-9c7d-11e5-a7e3-0002a5d5c51b

// If the device is already on a network and you need to change it, you can load:
// http://<device_ip>/common/get_wifi_setting
// It'll give you a result like... ret=OK,ssid=OldSSIDHere,security=mixed,key=%6e%65%76%65%72%67%6f%6e%6e%61%67%69%76%65%79%6f%75%75%70
// To update the same data, open that page and in the console, run this (modify as needed):
const ssid = 'NewSSIDHere';
const key = 'nevergonnagiveyouup';
const encoded = Array.from(key).map((c) => '%' + c.charCodeAt(0).toString(16).padStart(2, '0')).join('');
