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 ...

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.

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 ...

Install MQTT on domoticz
