I backed the Sonoff NSPanel Smart Scene Wall Switch on Kickstarter in October 2021, paying about S$85 all-in. It was perhaps the fastest Kickstarter to deliver, fully funded within a month and far exceeding Sonoff's goal.
After my MCO switches dropped off Z-Wave, I moved to Sonoff T2UK Wi-Fi switches. With most lights now on Sonoff, I added the RM 433 remote to control up to eight via 433MHz.
The Sonoff Micro USB Smart Adaptor, S$13.99 on Lazada, lets you control any USB device remotely via the eWeLink app. I couldn't pair it on my iPhone 12 Pro Max, but a SIM-less Pixel 3a worked.
Since starting my smart home in 2016, I'd relied on MCO Z-Wave switches, but my Series 4 units began failing after a year. This review covers my move to the Wi-Fi-based Sonoff T2UK smart wall switch.
