$7 Sonoff D1 Smart Dimmer Switch Supports Mobile App, RF433 Remote, and Voice Assistants

ITEAD Studio Sonoff is a family of WiFi or/and 433 MHz RF connected smart home switches, sockets, light bulbs or other products for home automation. They are usually based on ESP8266 WiSoC and while the pre-loaded firmware works with eWelink Android/iOS app and popular voice assistant, it’s also possible to load open-source firmware such as Sonoff-Tasmota or ESPurna to add MQTT and other protocols in order to integrate those with home automation solution such as Domoticz, or something control those from your web browser.

The company has now launched another Sonoff device, namely Sonoff D1 smart dimmer switch which – as its name implies – will allow you to dim incandescent and dimmable LED lights.

Sonoff D1 smart dimmer switch specifications:

  • Connectivity – RF433 and 802.11b/g/n WiFi 4
  • Max Current – 1A
  • Max Power – 400W for Incandescent lamp, and 150W for LED light
  • Power Supply – 110V-230V AC input & output
  • Mechanical
    • Dimensions – 62 x 47 x 32.5 mm
    • Compatible with US, EU, and 86 type mounting box
    • PC V0 material

By default, the switch can be controlled using eWelink app or voice commands through Google Assistant or Amazon Alexa, but the device also comes with an optional RF433 base and remote control powered by a 12V battery.

It can be installed in your existing light switch box, replacing the mechanical switch as shown in the video below, and also shows the three ways to dim the light after installation.

Sonoff D1 smart dimmer switch has just launched and can be purchased for $7.14 (35% discount) until December 15, after which the price will go back to $10.99. If you’d like to use the remote control, you’ll need to add the RF433 base and the remote control for respectively $1.89 and $3.84.

For further information on how to use the smart dimmer, you may read the multilingual user manual or quick start guide. I could not find any information about support for Sonoff-Tasmota or ESPurna at this stage, but it should eventually be supported at least in the former.
