Hi all,
I’m trying to integrate the data from my new gas meter into home assistant. This is the model they just installed:
https://www.metersit.com/en/products/residential-meters/domusnext-g4-169-en
I’m wondering if somebody had any luck with it ?
I’m going to trying playing with this:
I will report back if I find something. In the meantime, any advice is appreciated!

Hi Thomas,
have you got luck with it?
My house has the same Gas Meter series (Metersit G6 GPRS) and I was trying to get the data in HA.
Please, let me know what you discover so we can try to work together on it but from what I understand I’m already out because not having MBUS series…

Hi,
Please be aware that your G4 is using MBUS Narrowband which works on 169MhZ Frequencies. The im871A does only support mbus over 868MhZ, so it will not work.
You need to buy an AMB3665 dongle for that.
I’ve got a different Gas Meter (SamGas - Pietro Fiorentini) and already doing some research to decode the protocol (I’m already logging some telegrams, many of them from a metersit G4 like yours).
You can find my issue on wmusmeters github here:

### Type of request
New device support
### Meter description
Please add suppo… rt for SamGas (Pietro Fiorentini) G4 N1A (169MhZ) devices.
This is the link of the product (With details both in italian and in English language)

I've got an Amber 3665 with some telegrams decoded (from my and my neighbours devices), attached in the next form.
I can log other telegrams if needed, or I can try to decode them by myselfs.
I can write C/C++ code but I don't know anything related to MBUS (Wired and wireless) protocols...
Thanks!
### Logged telegrams from meter in decrypted format

The Telegrams are for different Samgas meters, (Same model)

I did not manage to get it to work… Probably PxPert is correct.
I’m tempted to use this other dongle, but it’s a bit expensive for a not so well documented use case that could lead nowhere…

Hi, could you tell me what mode you are using, which gives you reading from the metersit G4. n1a, n1f… ? Thanks
