Combining EKM Push and ISerial?

Dear Forum/Jameson,

I now am the proud owner of an EKM Push and ISerial.

Whilst the Push has lots of advantages over the ISerial, the later can actually control settings in the Omnimeter, which is really nice too.

--> Can I combine both by simply connecting the RS485 A+ and B- to both the Push and the ISerial?

That would be awesome!

with regards

Yes, you can do this (though this would be a multi master network and is not generally encouraged). There are a couple things to be aware of. You can only have 1 master communicating at a time. So if your iSerial and EKM Push make a request at the same time, you will get data collisions and garbled data. This is not a big problem, it just results in a single bad read. So you will want to read your meters once a minute with both the iSerial and EKM Push and hope they do not conflict very often (for example).

The EKM Dash is not setup to read your meters through both. I would use the EKM Dash with the iSerial, and the EKM Widget or with the EKM Push data in this case.

Good luck!

Thanks, I will install accordingly and report back - looks like it will be a great set-up!

Hello Jameson, I installed accordingly, and this can work to some extend - but the number of "bad meter read" or "no response - check …" is too large (as in most of the returns) so I will use the EKM Push and have powered down the iSerial. I leave the iSerial wired, so that when needed and I am at the home I can power it back up to change e.g. the pulse ratio.
