Hexing HXE115-KP

Good morning,

I changed inactivity timeout to 60sec - symptoms stays the same.

Hereunder the logs:

It is as if we're sending the wrong OBIS code to meter, hence it does not respond.

I also did some tests on the same meter with EZReader software (https://icube.ch/) which requests the Object list from meter. Meter responds with ObjectUnavailable

Any further suggestions will greatly be appreciated.

Good day,

Thank you for your response.

I managed to get hold of a Hexing HXE130 smart meter - with pretty much same results.

Can you possibly find a certificate for this meter?
