CHEAP IRBLASTER for domoticz Project

[dvsat]

Hi,

I have create a small project to allow using an IR Blaster with domoticz, Jarvis or Alexa.



You will need :

Hardware:
-Nodemcu
-Wire
-IR Led
-IR reciever
-Resitor 20 ohms

Software :
-Mosquitto
-OpenSSL
-MongoDB
-Node-Red



At the end you could reprodce any IR signal with a simple URL like :

http://<noderedsite>/IRSend?irDevice=<DEVICEMAC>&irCode=0xCA31DA45

Chear !

Interesting.... Still have to rearrange my ir node from Mysensors.

Can you set it in learning mode? So it will add a switch or something.
Or do you have to set the IR codes in the sketch.

Yes it could learn signal from the IR reciever and store the Full DATA RAW and the HEXCODE in a mondoDB. By this way, you should be able to use any UNKNOW device in futur.

OK nice I have the parts laying around. So will play with it. Thanks for sharing.

It cant connect to the Wifi network.

I changed the config.h with the broker name: i called it IR
And dont really sure what to do with the fingerprint.

Maybe you can expand your tutorial a bit for the more Noob types. Who want to learn but need point in the right direction.

Hi,

You should use a MQTT server with a valide certificate. (E.G. : Mosquitto + Let's Encrypt)

If you don't know how to build it, uses this one for free : https://www.cloudmqtt.com/

const char* broker = "m21.cloudmqtt.com";
// SHA1 fingerprint of the certificate
// openssl x509 -fingerprint -in <certificate>.crt
const char* fingerprint = "A5 02 FF 13 99 9F 8B 39 8E F1 83 4F 11 23 65 0B 32 36 FC 07";
