Not getting any further than Hello From XXX running SMlReader.

In the debug it is waiting for Sequence. Tried a couple of BPW 40 :(

Tried with Nodemcu and wemos d1

What's the model of the meter you are trying to read?

realfire23 commented 3 years ago

hi,

thank you for the fast reply.

Its a Landis+Gyr E220.

mruettgers commented 3 years ago

Did you unlock your meter by entering the PIN code provided by the provider via a flashlight?

I'm working on a new version of SMLReader that will allow debugging (including outputting RAW data read by the phototransistor) via web interface. And I'm also planning to build a small application that will make a ESP8266 emulating a meter by providing SML data via an LED.

realfire23 commented 3 years ago

The pin has been entered.

Iam pretty sure Iam messing something up :D so debugging possibilities are always welcome.

Just to be sure: Do I need to disable the pin, because I only enterred the ping once and the meter gets back into normal mode after 120 seconds.

Hello realfire,

your meter does not "speak" SML. It speaks what is often referred to as "D0" or IEC62056-21, which is roughly speaking an ASCII version of SML, which SMLReader does not understand, yet. Depeding on what you are trying to achieve, a workaround might be Tasmota or ESPLink. Regards, Dieter

where did you get that info ? according the specs I have it uses SML. Furthermore Volkszaehler and homemmatic integrated the meter already via sml ( as far as I understood of course)

Hello, you might be right. with the second look, I also saw the SML note in the manual. I guessed because according to this list: https://www.loxone.com/enen/info/smart-energy-meter-list/ most of Landis+Gyr meters don't use SML.

I can confirm that Landis+Gyr E220 works with SMLReader. This is not a software issue. topic can be closed.
