I am trying to enter a The Things Network application as an integration with Home Assistant. I keep getting “Invalid Authentication” even though I have doublechecked everything (host, id and API-key/password) with an MQTT-client.
I have also generated a new API-key for this just in case. What could be wrong ?
Found it out !
Simple but stupid - in the MQTT integration (and in any other MQTT-client) you need to set the “full” application id like @ttn. In the TTN-integration, you dont need that, you ONLY use the prefix/unique appid.
