New Module: SmartMeterP1. Read your DSMR electric/gas meter via P1 interface

[Paul Guijt]

Hello everyone,

I have a huge problem with my SmartMeterP1 device, and would appreciate any help.

I have an ISKRA MT382 smart meter (see photo), and FHEM running on a Raspberry Pi 2B. In FHEM my SmartMeter is defined: defmod SmartMeter SmartMeterP1 /dev/ttyUSB1@9600,7,E,1.

At start everything worked as expected. Yesterday, out of the blue, an internal called PARTIAL started showing all kind of jibberish and the readings stopped updating.

Trying to solve the problem I removed the P1 plug for 10 seconds and re-installed the SmartMeter device in FHEM.

The SmartMeter log shows the start of the mayhem at 10:25:15:

FHEM was down at that time, so had nothing logged. Syslog didn't show anything useful around that time. Kernlog documents about the USB ports:

As we all think occasionally: what could possibly go wrong??

Again: any help is highly appreciated!

I had the usb port wrong...

Nice job Michel, thanks. Smashed out my Cacti scripts immediately. With the help of the Statistics module and some userReadings the family's daily energy spend is now visible in FTUI. The WAF is 100% 

Best regards,
Ed

Hi Ed,

I am really interested how you set this up. Can you attach your configuration?
Thanks in advance.

Hi there,
a few days ago my smartmeter has been exchanged. The old one was read out without problem and the new one works fine for the electricity values.
However, the gas data is not read out anymore. It only reads a constant (wrong) value. I saw that the gas meter can have channel 1, 2, 3 or 4 according to OBIS reference and that in the .pm module only channel 1 is read out. My guess is that my new smartmeter is now using not channel 1 like the old one but channel 2, 3, or 4 instead. Would it be possible to update the smartmeterP1 module such that it becomes possible to choose the channel?
That would be truly great!
Thanks,
Kirin

Hi,

The low & normal tariff are switched in FHEM compared to what is set up in my belgian meter.

Any way to switch them within FHEM ?

Thanks !
