Purchase

There are several clones of this device -- use the Teckin device:

  • Gosund SP1 (Version 2.3 and 2.4)
    • To configure select Gosund SP1 v23 (55) or console command Module 55
  • BlitzWolf SHP2 (Version 2.3 and 2.4)

Watch out: SP1 devices sold nowadays do not always contain a ESP8266. Variants are around with a W701 cpu, which is incompatible with Tasmota!!~

Calibration~

If you have another (better) volt and power meter, this procedure should increase the precision. Use an incandescent bulb or an iron. In the web UI Console, enter the (correct) readings using the following commands:

Backlog VoltageSet <voltage>; CurrentSet <current>; PowerSet <wattage>
