Wemos D1 mini and Wemos relay shield

Configuration

Hi

I have Wemos D1 mini and Wemos relay shield. Where can i find some working code for that ? Can’t find anything…

It is just a switch toggle. There should be an example to turn a LED on/off in the Arduino IDE, it is the same thing. I believe the relay uses D1 as the switch.

Finally found switching code from here. https://diyprojects.io/esp8266-dht22-mqtt-make-iot-include-home-assistant/#.Wows_KiWaUk

Wemos d2 to relay d1 and it works. Sorry im just new in this business :slight_smile:

Hi,

I’m novice in Mqtt… and bad in English.
I try to configure my Wemos relay shield, with this configuration in configuration.yaml:

switch:
  - platform: mqtt
    name: "Lampe"
    command_topic: "lampe/gpio/5"
    state_topic: "lampe/gpio/5/state"
    payload_on: "1"
    payload_off: "0"
    qos: 1
    retain: true

And nothing happened…


The Wemos is connected with HA, I can read Humidity and temperature from them:

 MQTT : Connected to broker with client ID: ESPClient_2C:F4:32:13:14:46
822211: Subscribed to: lampe/#
822213: EVENT: MQTT#Connected
822387: DHT : Temperature: 0.00
822387: DHT : Humidity: 86.00
822390: EVENT: DHT#Temperature=0.00
822437: EVENT: DHT#Humidity=86.00
822448: Domoticz: Sensortype: 2 idx: 289 values: 0.00;86.00;3
822935: SW : GPIO 5 Set to 1

I’m not able to create a device in ESPEasy because GPIO 5 is unavailable.

I’m on Domoticz and can trigger the relay in http, I would like to use HA instead Domoticz… What is the good way ?
