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.

||
## Components used
|
||
|
||
1. The housing from Broadling RM Pro+
|
||
1. [Wemos D1 mini](https://www.wemos.cc/en/latest/d1/d1_mini.html) development board
|
||
1. [Wemos IR shield](https://www.wemos.cc/en/latest/d1_mini_shield/ir.html)
|
||
1. USB to micro-USB cable
|
||
|
||
## Assembling
|
||
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:
|
||
|
||
|
||
|
||
## Using
|
||
|
||
In ESPHome let’s create a config:
|
||
|
||
```yaml
|
||
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](https://esphome.io/components/remote_receiver.html). Also pay attention on `logger` section. It is set to `DEBUG` level.
|
||
|
||
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](https://esphome.io/components/remote_transmitter.html) component to build, for example, something like [this](/2021-01-13-building-wifi-ir-remote-control-for-any-tv-with-esp8266-wemos-d1-mini-and-esphome/index.md). |
