16xRelay with ESP12F Onboard and two Shift Register (74HC595)

ESPHome
62

I just received one of these newer esp32 boards also. I swore I searched here and never found this code. 4 hours later got it all figured out and then found this code as I was going to leave it on the forums for others.

My next step will be to design a 3D printable case. @FVBH did you ever find one?

63

care to share your code and your STL’s of the case ?

I choose a standard casing normaly used as an electrical cable box (big version of that) at my local HomeDepot (or Hornbach as is is called here in Europe :slight_smile:

64

I have this board and have issues getting it working. The relays are not showing on the device web page and not in HA. The board I have is the same just an ESP32E

65

This does not sound like a problem with the board but your code.
Even if nothing is working, ESPHome and HA should display the switches.

But as you did not post your code, there will be nothing else we could help you with

I also see this error in the esp web page.

But I would expect to see the relay switches in the web page of the ESP32

Any help would be great.

Code is above

You should open an ESPHome issue.
There is nothing wrong with your config.

Please install an older version of ESPHome (From Jan 2024) and let us know if the same behaviour exists.

Thank you,

How do I install an older version? Sorry still new to all this.

70

many Thanks, weeks of try an error done!!! Amazing, Great Work!

Use code provided on valve_controller.ino. You need to change ssid and password accordingly and local IP too.
It only works locally.

I searched for hours and finally came across this topic. Thanks to everyone who shared the sample code.
