The MQTT items are a mixture of Tasmota flashed Brilliant, Arlec and Kogan plugs, switches and ceiling fan controllers.
Pretty much all of my lights are Yeelights, but I have also some flashed Arlec and Brilliant bulbs (Tasmota/MQTT) and some led strips that use the Flux LED component.
I have a few TP-Link plugs, a few WeMo switches. Total is over 50 WiFi devices, excluding phones, laptops, TVs etc.
Sure am, in Brissy also
