Hi Mohan,

Please, don't ask for updates. I'll answer as soon as I have time.

When you set keys data is encrypted automatically. There is an issue with data that meter sends.
The size of the ciphered service is invalid (zero). Ask your meter manufacturer to fix it.

Hi Mikko,

I will ask meter manufacturer to fix this and share you proper ciphered push message. So that you can tell me what are things i have to follow to interpret and get the data.

Hi Mohan,

Before this is fixed to the meter you can't get the decrypted data.
