Hi all,
Over the last few months, I’ve been learning about LoRa, LoRaWAN, and TTN, and it’s been very exciting.
I bought a Dragino LHT52 sensor and registered it in the TTN Console and physicaly installed it in Amsterdam-Zuid.
There is a gateway located about 700 meters away.
The problem:
When I insert the batteries, the LED sequence is green → red → blue → green, which seems correct.
However, the final green LED should stay on for about 5 seconds to indicate that the join was successful, but this does not happen.
In the TTN Console, I do not see any live data, and in the session information I get the message:
“This device has not joined the network yet.”

What I tried:

-
Read the Dragino documentation
-
Read other relevant forum posts
-
Google searches
-
Asked ChatGPT
-
Verified that the AppEUI, DevEUI, and AppKey in the TTN Console match the values on the sensor package
-
Reset the sensor
-
Removed and reinserted the batteries
Does anyone have any idea what could be the issue?
Thanks.
