Homekit firmware for SWb3 powerstrip

25-april-2022 New capability added to preserve the power state over a power outage. By default the state will not be preserved, if you want to change the default to preserve the state then using Eve app set "Preserve State" to "On"

This is for the 3 socket, 2 USB port, SWB3 powerstrip, sold under the brands SIPAILING, LINHGANZH, YAGALA.

One button press turn on or off scoket one, two button presses turns on or off all scoket.

I had to open the devices to flash the firmware, as they use TUYA wifi circuits and I have not found a way yet to flash this with our homekit firmwares OTA. Once the firmware is on there then OTA flashing will work for future updates.
