Sonoff Wireless Switch Family Gets a $3 IP66 Waterproof Enclosure

ESP8266 powered ITEAD Studio Sonoff wireless switches have been popular because they are inexpensive, highly customizable thanks to work from the community leading to open source projects such as ESPurna and Sonoff-Tasmota, and come fully packaged so you don’t need to make your own case for it.

That works well for indoor projects, but if you needed to control outdoors lights, gate, water pump, etc… you had to protect the device from humidity/rain. That may not be necessary anymore as the company is now selling Sonoff Basic with an IP66 waterproof enclosure for $7.75, or the case only for $2.90.Sonoff waterproof case:

  • Ingress Protection Rating – IP66
  • Material – PC V0
  • Dimensions – 132.2 x 68.7 x 50.1mm (See details)
  • Weight – 145.0g

IP66 rating is not suitable for prolonged immersion, but it should be good to protect against rain or high humidity. The box ships with two standardized PG7 waterproof connectors, and is large enough for Sonoff Basic. The enclosure can also be used for the larger Sonoff POW/TH10/TH16/DUAL or G1 switches but you’ll have to take out the board from those devices.

One potential use case is for outdoors Christmas lights, and ITEAD provides instructions just for that explaining how to install Sonoff Basic in the IP66 enclosure, and control an LED light strip. The video below demonstrates the waterproofness of the case.
