Quick step-by-step guide on assembling an IR receiver for reading IR codes from your remotes based on Wemos D1 mini, Wemos IR shield, and using ESPHome.
- The housing from Broadling RM Pro+
- Wemos D1 mini development board
- Wemos IR shield
- USB to micro-USB cambe
First of all, we need to make our shield work with all transmitting LEDs and the pins we need. In this example, we will use
D3 for sending and
D4 for receiving.
Now lets put the board into the housing with cable connected and glue it all:
Then put the shield on top:
Finally, close the housing:
In ESPHome let’s create a config:
esphome: name: ir_receiver platform: ESP8266 board: d1_mini wifi: ssid: "WiFi" password: "************" # Enable fallback hotspot (captive portal) in case wifi connection fails ap: ssid: "IR Receiver" password: "************" captive_portal: # Enable logging logger: level: DEBUG # Enable Home Assistant API api: password: "************" ota: password: "************" remote_receiver: pin: number: D4 inverted: true dump: - samsung
As you can see it is set up to dump only Samsung-specific codes. You can read more about reading other codes on esphome.io. Also pay attention on
logger section. It is set to
Compile, flash, open logs and start firing into our device with your IR remote. You’ll see something like this:
[17:34:48][D][remote.samsung:055]: Received Samsung: data=0xE0E007F8 [17:34:51][D][remote.samsung:055]: Received Samsung: data=0xE0E020DF
You can now use this data with the ESPHome Remote Transmitter component to build, for example, something like this.
