Both these meters are available with M-BUS or modbus communication options, however this is an option and not standard. You’ll need to check your full part number (see below) to see if you have these communication options. Unfortunately these communication options cannot be retrofitted.
I took a picture with the Kamstrup on - and wonder if it is a WIFI thing I have -
See the antenna in the bottom - or does that indicate something else…?
Regarding the EM340 - I have no idea how to identify the one I have - none of the numbers make sence to me… Allthough I went into menu and in there were some Pul Rate - not sure what it is either though… Hopefully I have not done any harm in there… LOL
On the heat meter You have the digits 21 as the last two but one digits of the model number, this should indicate you have a 2m wired mbus cable. But I can’t see this cable in your photos. Can you see a two core cable coming from the heat meter.
I’m not familer with these meters, we use the Kamstrup 403 which has user upgradeable communication modules.
Regarding the electric meter you could check to see what ports are available inside.
Thanks, I’m assuming that mean it has wireless MBUS? The product code indicates that it’s got wired MBUS? I would expect to see a ‘30’ in the product code if it had wireless MBUS?
We need wired MBUS for heat pump monitoring since wireless MBUS does not support 10s readings.
Which supports the C1 mode it is capable of transmitting - also forund some Win software that might suit my needs on the short lane - I currently do not have the funds for the emoncms, unfortunately - could have been a blast - so I have to test/try with less for now.
I do have a Rasperyy Pi somewhere - belive it is an 3 + something… which I can try with as well if the winslow thing does not work
This will pick up the wireless signal and make it available as wired mbus. It will also allow you to enter the AES key (kamstrup meters typically send encrypted packets) and decrypt the wireless signal before making it available on the wired mbus.
You can then use the standard mbus code and dongle to read it.
Actually you might even be able to use usb directly. I’ve not tried this but I think the mbconfig software is just sending serial over the usb for programming.
