AOFO C730 power strip

hebom · December 30, 2023, 10:36am

Hi there,
I’ve got a AOFO C730 power strip and I’ve replaced the CB2S with a ESP-02S, all relays are working but I can’t seem to get the button and status-light working. Any help would be appreciated. If you happen to know a place where I can find some more details on the ESP-02S, that would be appreciated since ESP-02S TYWE2S Replacement Module (ESP-02S) Configuration for Tasmota (blakadder.com) is confuzing (the GPIO’s don’t match the image).

My current YAML looks like this:

GPIO03 is RX.

  - platform: gpio
    pin:
      number: GPIO03
      mode: INPUT_PULLUP
      inverted: True
    name: "Device - GPIO3"

I’ve tried with and without mode and inverted but that doesn’t change anything, it still won’t register a button press.

I’ve found the issue
GPIO01 is the button
GPIO03 is the status-light

Now continue tinkering with the YAML

My current template version.
I’ve split up the config in multiple YAML’s, so if I change my WiFi-settings it will change for all devices. Because I’m using this for my aquarium I’ve also connected a DS18B20 sensor and that sensor will turn on/off the heating in case the temperature gets to cold/warm. I’m also going to implement a safeguard for my pump and an integration with HA so I can bypass the safeguard for a certain time.
