ZLD-44-EU-W Powerstrip @ ESPHome

Greetings.

I would appreciate help with powerstrip configuration for ESPHome. I got covered every relay switch, the only thing eludes me is a POWER BUTTON (which is a binary sensor): it requires a script, which toggles all sockets ON and OFF simultaneously. I went with lambdas: on_click I check if retrieved state is ‘true’, turn all sockets off, publish_state(id) to ‘false’ and vice versa. I got it to this part:

binary_sensor:
  - platform: gpio
    pin: 3
    name: zld_44eu_w_button
    id: pwr
    on_click:
      min_length: 50ms
      max_length: 500ms
      then:
        lambda: !lambda |-
          if (id(pwr).state) {
            id(zld_44eu_w_relay1).turn_off();
            id(zld_44eu_w_relay2).turn_off();
            id(zld_44eu_w_relay3).turn_off();
            id(zld_44eu_w_relay4).turn_off();
            id(zld_44eu_w_relay_usb).turn_off();
            id(pwr).publish_state(false);
          } else {
            id(zld_44eu_w_relay1).turn_on();
            id(zld_44eu_w_relay2).turn_on();
            id(zld_44eu_w_relay3).turn_on();
            id(zld_44eu_w_relay4).turn_on();
            id(zld_44eu_w_relay_usb).turn_on();
            id(pwr).publish_state(true);

I got GPIOs right, so I’m clearly missing something in the code, because button toggles power on once by double-clicking and not working at all after that. Single click doesn’t work at all, plus once sockets are on, they won’t switch off via the button, only though HA interface. Where am I wrong exactly?

Thank you in advance.

There is a sample code here https://esphome-configs.io/devices/brilliant-smart-powerboard/

It does more than you want, but may give inspiration.

Thank you kindly, dear Sir!

I totally missed the idea that lambda condition checks are the same with C++ :open_mouth:
Plus, I misiterpreted button states, so for me this piece of code goes like this:

binary_sensor:
  - platform: gpio
    pin: 3
    name: zld_44eu_w_button
    internal: true
    on_press:
      lambda: |-
        if (! (id(zld_44eu_w_relay1).state || id(zld_44eu_w_relay2).state || id(zld_44eu_w_relay3).state || id(zld_44eu_w_relay4).state || id(zld_44eu_w_relay_usb).state)) {
          id(zld_44eu_w_relay1).turn_on();
          id(zld_44eu_w_relay2).turn_on();
          id(zld_44eu_w_relay3).turn_on();
          id(zld_44eu_w_relay4).turn_on();
          id(zld_44eu_w_relay_usb).turn_on();
        } else {
          id(zld_44eu_w_relay1).turn_off();
          id(zld_44eu_w_relay2).turn_off();
          id(zld_44eu_w_relay3).turn_off();
          id(zld_44eu_w_relay4).turn_off();
          id(zld_44eu_w_relay_usb).turn_off();
        }

“If any of the relays are on - turn everything off, otherwise - turn everything on”
Now I have to realise how to restore relays to previous condition individually, not turn them on all at once.

Glad you got it sorted. I claim no credit for the code though. I copied it from another config.

hey @YujiTFD i finally managed to flash this strip with esphome. would you mind sharing your full config for this device?

Hi there.
You message caught me on the train station, leaving city for a day :slight_smile: I will return by Wednesday, stay in touch.

Hello again.
Full code below. Again, it’s a single-click logic “If any of the relays are on - turn everything off, otherwise - turn everything on”:

  esp8266_restore_from_flash: false

  ssid: !secret wifi_ssid_liot
  password: !secret wifi_password_liot
  fast_connect: on

# Enable fallback hotspot (captive portal) in case wifi connection fails
  ap:

#    password: !secret ap_password

captive_portal:

          id(zld_44eu_w_relay_usb).turn_on();
        } else {
