May 22, 2022May 22, 2022 Peter ScargillGeneral7 Comments on Sonoff DW2-Wi-Fi Door Sensor and Node-Red

Ok, first things first, the DW2-Wi-Wi door sensor is as it says, WiFi, not RF or Bluetooth (though it does use BT to setup with the eWeLink APP in the first place). I looked here on Amazon and read someone saying the device was almost impossible to pair – mine…

November 14, 2017November 14, 2017 Peter Scargillalexa, bigtimer, Node Red29 Comments on Node-Red and Alexa with Big Timer

Toying with HA-BRIDGE

November 10, 2016November 13, 2016 Peter ScargillGeneral29 Comments on Toying with HA-BRIDGE
