{"NAME":"BlitzWolf SHP","GPIO":[57,255,56,255,0,134,0,0,131,17,132,21,0],"FLAG":0,"BASE":45}

For more accurate energy consumption measurements this device requires power monitoring calibration.

Hardware Revision

There is a newer hardware revision (v2.3) working with this template:

{"NAME":"BW-SHP2 16A","GPIO":[0,57,0,17,134,132,0,0,131,56,21,0,0],"FLAG":0,"BASE":45}

Flashing

Please see the Hardware Preparation page for general instructions.

Step 1.

Be sure it is NOT plugged in! Remove the 4 triangle screws. Triangular 2.3mm Screwdriver required (a Torx T6 works well too)!

Step 2.

Solder cables to the ESP Pins

Step 3.

Connect serial adapter and make a shortwire between Pin IO0 and GND during startup. (For entering flashmode) RX and TX must be crossed.

Step 4.

Flash Tasmota

Pin layout hardware revision v2.4

Template for revision v2.3 is working, only the pin layout has changed.
