Review on 🔌 SONOFF Smart Switch for Enhanced Control and Automation by Kevin Singh

Sonoff Mini is their answer to Shelly-1. The programming pins aren't accessible from the outside like Shelly's, but you can easily reach them. If you buy them as a set, you reduce the unit cost. The units are small and fit in single and double wall plastic junction boxes in the US. Things can get tight when running more than 4 cables into a single back box under 18 cu. in. Everything fits nicely in the 22cc. in. box. If you use Wago connectors instead of wire nuts, you can squeeze out a little more space. (please no flame)
