Using Slimmelezer+ to read data from energy meter Iskra AM550 from Romande Energie (Switzerland)

ESPHome
61

A bit of reading wouldn’t hurt (just a few posts above). :wink:

And get a Slimmelezer as hardware.

62

Or, if you want an out of the box working solution, then get a P1 Meter from HomeWizard.

63

Hello there,

I just received my Slimmelezer and I tried all of the listed suggestion here but I cannot get it to read any value. I always have this warning “[dsmr:092]: Timeout while reading data for telegram” what am I missing?

Thanks in adavance for your help.

Is the P1 port enabled on your meter? (And which meter, what DSO and which country?)

65

Thank you for your answer. It’s an Iskra AM 550 provided by Romande Energie switzerland. I think the port is active since I can power the p1meter from the rj12 only.

You should have a small arrow on the bottom of the LCD at the COM text. (To be honest, I am not sure how is that worded on those meters for Romande.) But there are like 8 positions on the bottom one should indicate that the P1 active. One of the right side ones, maybe the 6th or 7th from the left.

ISKRA produces multiple models of the AM550 with different displays as well. Just look at the Dutch ones for example.

Otherwise, are you using ESPHome? This part suggest that.

You should be using this:

Ok, I will check. Yes I am using ESPHome. I saw this post but it looks more complicated than the stock firmware for the slimmelezer and I am not sure how to compile the binary from this git.

68

The ESPHome component does not support HDLC/DLMS to my understanding. It supports only DSMR. DLMS is overcomplicated and generally a pain in the …

The linked Github project is not so complicated if you have used Arduino IDE, or programmed any ESP device, but not with ESPHome. Just follow the instructions and read the wiki. First of all get a PlatformIO as suggested.

69

Ok I installed the platform IO extension in vscode. I cloned the git. Now I am culeless about the building process.

70

Open the platformio.ini with vscode, it should recognise what it is.

Then you can follow this video how to flash the ESP.

Or you can flash the ESP from the compiled code. Flashing · UtilitechAS/amsreader-firmware Wiki · GitHub

I am stuck with Slimmelezer+
Trying to make it work for Encrypted P1 port with DLMs protocol (Austria)
I have the P1 port activated and the decryption key
My hope is on amsreader - but my trials are unsuccessful.
Can it be that decryption of amsreader is not working (different type) for my Smartmeter (ISKRA AM550) ?
The Encryption used in teh Smartmeter is: “Cosem Suit 0; HLS; AES128”
My decryption key length is 32 digits. Is it correct that amsreader key length is 64 digits?

Any sugestions are welcome - thankx

72

HLS means High Level Security. Read about it here:

No, amsreader has no capability to do this.

@Jack-Harper did you ever resolve this? I have a different meter (Landis+Gyr E360) but same result “[dsmr:092]: Timeout while reading data for telegram”
