ES30F27 FAQ

I bought it from Amazon

https://www.amazon.com/dp/B0F43MYK6W?ref=ppx_yo2ov_dt_b_fed_asin_title

It clearly says 24 volts on the page, but I didn’t see that so it was my fault.

I cannot find it on amazon even searching for it. I had found it searching for ESP32 interface boards.

Do you have any sample YAML code to use with this? I think that it would be somewhat complex to get the serial - parallel shift registers to work correctly.

I got the LED to turn on and off with a ‘button’ within Home Assistant / ESPHome with the following YAML code.

=============================================
esphome:

esp32:

# Enable logging

wifi:

switch:

pin: GPIO16
name: "Board Light"
=================

I have the relays working.  At least to the point that the LED lights come on. I also have the LED light by the power light working.

Below is the YAML code for this part.  I do not have the other stuff working yet but am working on it.  I will update you as I do, and then you give this code out to other people wanting to use this with Home Assistant.

I feel that if you have the code available in with the rest of the documentation, it will make people with Home Assistant MUCH more likely to by the unit.  I know that if I knew it was available, I would have bought even quicker than I did.

 

Answer

1. If you purchased a 24V power supply, you can use a 24V DC power supply.
2. We don't know how to develop with ESPHome, but we do provide Arduino code. Download link:
