[Question] Does this also work with a SAIA M-Bus energy meter

Open Kurisutian opened this issue 2 years ago • 4 comments

Hi, while searching for a solution to integrate my SAIA M-Bus energy meter (https://sbc-support.com/en/search/?q=ale3b5f+mbus&tx_solr[filter][0]= 3) into ESPHome I found this repo and I was wondering whether it will also work to get the SAIA energy meter running or what eventually needs to be adjusted to do so. So far I couldn't get it to work and the MBus slave device mentioned in the docs is the same I am using so I'm curious about how to get it working with your example eventually. Do you happen to know if this might work? Thanks a lot!

If your packet starts with 68 FA FA 68 it may be supported but it's unlikely since every provider has to do their own thing.

Thanks for the information. Stupid question as this is my first encounter with something that was not working out of the box: What do I need to do to just get the packet(s)? I did not yet find out how to simply pass anything to the logs and be able to get further information from there. I checked the manual(s) from the link I posted but how do I actually parse the sensor data so I can compare or kinda use them? 🙈

If you already have an ESP with ESPHome connected you can just set the logger component to VERBOSE and you should see incoming data on your UART port.

From my own experience of implementing a smart meter gateway prototype for one of the companies mentioned in this github repository: the mbus implementation always seemed to be well done. when you manage to decrypt the data, its usually no issue to parse it anymore - but different meters use different sensor types/ids or worse, their own idea of how the data should be represented (endianess, data type, .....)

https://m-bus.com/ or the documentation of the meter is helpful there. Supporting other meters should not be hard, but it might need some coding to support new/other sensors.
