My Own custom POW
Posted: 13 Oct 2017, 14:50
I've realized my own enhanced version of POW running of course ESPasy.
I used the same HLW8012 circuit taken from the POW schematich, I designed a custom PCB with proper safety (including inline high voltage Fuse holder, varistor for optional additional filtering, front LED to show relay status and an "hidden" touch button to toggle relay manually if needed; cerry on top, I connected the HLW8012 chip to different pins than POW in order to freeup I2C bus and connect a nice 0.96" OLED.
All is designed to fit a "standard" mechanical timer (after you strip off all the internal hardware of course) just waiting a friend of mine to print a nice top-cover with hole mounting place for the OLED.
If someone is interested in the gerber file I can share, just be alerted I used mainly SMD components in order to keep the size small enough to fit the enclosure.
