After I got the Edifier R1700BT Speaker I notice that i want to control them like all my other stuff with my moile phone and MQTT. So i got some IR reciver and LEDs to simulate the Edifier Remote with a Wemos who is connected to my MQTT Server.

I figure out the IR-Codes used:
|
||
|
|
|
||
|
|
* 149389439 -> power on/off
|
||
|
|
* 149356799 -> mute
|
||
|
|
* 149369039 -> Volume Up
|
||
|
|
* 149393519 -> Volume Down
|
||
|
|
* 149377199 -> Switch input to Bluetooth
|
||
|
|
* 149399639 -> Switch input to Line In
|
||
|
|
|
||
|
|
## Hardware
|
||
|
|
|
||
|
|
I connected the IR-LED to the D4 Pin of a Wemos. I used [this question](https://antwortenhier.me/q/wie-steuere-ich-die-ir-led-mit-esp8266-pint-bei-3-3-v-und-mosfet-um-einen-62376266277) as basic idea.

## Software
|
||
|
|
|
||
|
|
With this Numbers, and the [pubsubclient](https://github.com/knolleary/pubsubclient) and [IRremoteESP8266](https://github.com/crankyoldgit/IRremoteESP8266) i just can subscripe to some topics, and every time a message aravid at one of the topics i could send the code to the speaker:
|
||
|
|
|
||
|
|
```
|
||
|
|
if(String(topic)=="musik/power") {
|
||
|
|
irsend.sendNEC(149389439, 32);
|
||
|
|
Serial.println("EDIFIER: Power");
|
||
|
|
}
|
||
|
|
|
||
|
|
if(String(topic)=="musik/mute") {
|
||
|
|
irsend.sendNEC(149356799, 32);
|
||
|
|
Serial.println("EDIFIER: Mute");
|
||
|
|
}
|
||
|
|
|
||
|
|
if(String(topic)=="musik/down") {
|
||
|
|
irsend.sendNEC(149369039, 32);
|
||
|
|
Serial.println("EDIFIER: Down");
|
||
|
|
}
|
||
|
|
|
||
|
|
if(String(topic)=="musik/up") {
|
||
|
|
irsend.sendNEC(149393519, 32);
|
||
|
|
Serial.println("EDIFIER: UP");
|
||
|
|
}
|
||
|
|
|
||
|
|
if(String(topic)=="musik/bluetooth") {
|
||
|
|
irsend.sendNEC(149377199, 32);
|
||
|
|
Serial.println("EDIFIER: Bluetooth");
|
||
|
|
}
|
||
|
|
|
||
|
|
if(String(topic)=="musik/line") {
|
||
|
|
irsend.sendNEC(149399639, 32);
|
||
|
|
Serial.println("EDIFIER: Line");
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
## Final Result
|
||
|
|
|
||
|
|
After solder everything to a perforated board I got the following result.
|
||
|
|
|
||

|
||
|
|
|
||
|
|
Maybe I will create another smaller version to hide next to the speaker. For now it works.
