I currently have an EDMI Mk10d meter installed, and got a Solar system installed a month back. The meter has been reconfigured and i'm feeding into the grid and all that, all of that is fine.
I presently have codes 03 and 13 available on the meter, which show my cumulative usage from the grid (from the time the meter was installed?), and also my cumulative feed-in back to grid.
What i would really like to do is to be able to see live usage for my house, i.e. when i switch on my 2kw kettle, i want to walk to the meter and it should show "2kw current live usage" (lets just assume i have no stand-by appliances).
I used to be able to see this when i had a different brand of electronic (but not smart?) meter about a year back, but then this got switched out by AGL for the EDMI Mk10d.
Additionally seeing live feed-in kwh's (what solar is feeding into the grid this second) would also be very useful.
I emailed AGL support about this, and they asked me to ring PLUS ES (the smart meter maintenance people, from what i can tell), but they told me that what i'm asking for is not possible.
Is this really true? No way to see live usage in your house? Very frustrating if that is the case.

You can find the information on how to read your meter by visiting the following link.
Looking through the answers you got, I don’t think anyone really understood your question and what you are trying to do 🙂
I have the same meter type as you, and by looking online to find the manual for it, I think I can answer your question, although it does depend on how the meter was programmed.
This meter has two data sets it can display - Set A and Set B. Set A is shown by default, and usually has only minimal information. In my case, it is 03 (cumulative grid import) 13 (cumulative grid export), both of which are since the meter was installed, and date and time. That’s it.
You want data Set B. To show that, press the “Select” button on the meter for 1 second. You can then scroll through the Set B data (it will auto scroll through spending a couple of seconds on each data item, else press the “Select” button quickly to step to the next data item).
My meter steps through the following: L1 voltage, L2 voltage, L3 voltage, L1 current, L2 current, L3 current, PF (Power Factor), and instantaneous net usage (kWh). To go back to Set A, press Select again for 1 second, or just leave it to auto-scroll through all the data items in Set B and it will revert to Set A.
So while you can’t see instantaneous power in kW on any given phase, you can see instantaneous current which is good enough (multiply by 230V to get watts).
Like your knowledge of metering, I need your help if you don't mind.
I just got an EDMI meter MK10E. I am trying to connect my RTU to it to get data in realtime. The meter comes with a modem, but I do not want the modem, I want to use the RS232 Modbus to connect and move data to the cloud. What is your Idea?
I understood from your post that you want to do some type of Serial Data Logging from your EDMI meter and push that data to the cloud. Is my understanding correct?
Is reliability of the data logging important in this scenario? If so, why wouldn't you go the route of using Ethernet (Modbus TCP) and move past the entire serial experience?
Also, from a security of data perspective, you would benefit from some type of mediator box like a Modbus-to-SNMP mediator. It takes the Serial Modbus (RS-232) and converts the message to SNMP. You get better encryption of the data via SNMP when sending the data via IP to the cloud.
Also, with serial, in case there are communication errors from trying to read data from the registers, this would require some type of "Error Handling" to ensure the right data is sent to the cloud.
From your post, I didn't have enough information as to the use-case-scenario or your acceptance criteria or an explanation of why you wanted to try the Serial data logging method as opposed to the modern IP data logging, hence the above is what I could offer as suggestions.
Please note, I'm not an Engineer, but someone with an IT background.
Many thanks, Schander The hardware is installed in remote areas where only cellular or GSM will be used as a form of communication, hence the usage of RTU Modbus via Serial. Please feel free to advise. With Ethernet Modbus, it must be via a LAN, i guess? We also want the data log to be accurate
The challenge is finding a meter that is flexible. We want to connect the meter to a Gateway Router like Moxa via Serial RS232/486 Modbus.
I like the idea of implementing SNMP.
Any idea how I can find a supplier of the meter, how we can implement the solution, what we need to implement the solution?
