MQTT SSl and User

[Nailik]

Hello,

please add support when MQTT is set to require certificate and doesn't allow anonymous users. The thing with the user is pretty easy and i got it to work but the certificate just wont work.

I tried: mqttc.tls_set("/ssl/fullchain.pem", tls_version=ssl.PROTOCOL_TLSv1_2)

I'll take a look at it. I will need to first setup an MQTT server that requires TLS.

Would be awesome.

MQTT Setup (i use the hass addon)

  - username: '!secret mqtt_account'
    password: '!secret mqtt_password'
anonymous: false
customize:
  active: false
  folder: mosquitto

It also fails wenn i add mqttc.tls_set and set require_certificate: false

mqtt user auth has been added, although not tested.
