Hi Alias, tnx for your excellent post!

I've created some hardware (basically just 2 transisotrs and a sender and receiver infrered LED/transistor) and used the software you've linked to to test. Unfortunately, I get a Tout.

According to my energy supplier the infrared communication port is blocked.
Now I am wondering, is there a way to be sure it is blocked and that not my hardware is faulty?

Best regards,

Jeroen

Hi Jeroen,

For a first test you should keep your ir-head 1-2 cm over a white surface. Then, with Hterm or another serial client, send a few characters, this should then be displayed again in Hterm. Use the baudrate you have to use for your meter.
If so, your ir-head works. If not, there is something wrong with the ir-head or the further connection to your PC.

Udo

Hello Udo,

tnx for your reply, I've tested it and my hardware is OK. That's actually bad News, since that most likely means that my meter is blocked.
I can fix faulty hardware but I'm not going to open my meter

Does anybody else has experience with this?

Thanks again, Jeroen

Dear Jeroen
I new here and i wont to read out also the kwh meter
How did you manage to read out it . do you have a small schematic ?

Hi logger2,

have a look to volkszaehler.org . There you find schematics under hardware.

Dear Udo

Thx for you link , but i did hope there would be a very easy/small schematic just for testing . if port not is blocked. i want to readout and logg the kWh meter with a arduino
I hoped there would be already some software for it

greetings

Hi logger2,

then try this:

Dear Udo

That more like it , but the strange thing is there is no transmit line used
Which data is comming out of the kwh meter with this schema
the LED is blinking every 1000 times/kwh , i thought you have to send something information /request to the kwh meter , then you get the information what you are using for power
mybe am wrong ???

greetings

Hi logger2,

there are different type of meters in the world .
Some of them send the Data without request and some would like to get a request for the Data.
What is the name/type of your meter?

Regards
Udo

Dear Udo

I have a Ampy 5227C , if am correct it has a P0 port optical port with a red LED and a photo transistor
I had already contact with my supplier Liander, and they first advised the get a smart meter with a P1 port for read the consumption, retour(PV system)
But what i see on the internet is alot of some information about the protocol 62056-21. unfortunately not a complete informtion what i hoped to find for my kwh meter.
Liander did not know, if i could use this port. They first did not know if there was a optical port on the ampy.. later they called back , but they have to check at manufactorer if this port could be used and if it is not standard blocked.
i read the link http://www.domoticaforum.eu/viewtopic.php?f=71&t=7489 but thats not easy to convert it to C code for using in arduino

greetings

Hi logger2,

I have an AMPY5227F-E form Liander and use the optical port to read the meter.
Information obtained from this meter is:

Dear Folkert

But how did you manage to read it out, which hardware and software are you using?
and what is it responce time, can you readout it every X seconds?
Does you ampy has also a LED and photodiode
Greetings

Dear Folkert

this is a readout !

how did you manage that , which hardware and software did you use, What is it response time of the P0 port ..etc

greetings

Hi logger2,

I use homemade RS232 to IR reading head similar to the one as described at
volkszaeler.org RS232-IR-Schreib-Lesekopf.
This is connected to a windows PC with “HyperTerminal” terminal emulation program,
using 300 bit per second, 7 data bits, even parity, one stop bit and an line delay of 1000 ms.
Than I send an text file containing the “request message” and “acknowledgement/option message”,
the fist response from the AMPY meter falls between the two massages send.
Total transmission time at 300 bits per second is about 8 seconds.
The AMPY 5227 does not use an IR LED for transmission of data but the response data comes from the red LED that also blinks at 1000 imp/kW next to the IR photodiode.

Folkert

I also own an Ampy 5227 meter and I'm struggling with it.
This is my ir transceiver pcb:



I have removed the IR led and put some wires on it to get it closer to the Ampy.
When I use the Test1107 software the Ampy responses with a led burst when I press the Read button.
The problem is that after this the data doesn't come through, probably because the software can't handle this pcb like it should.
The pcb has a Profilic 2303 chipset and a terminal can communicate with it.
It has tx and rx leds, both are working when I type in the terminal and when I use a remote to send some ir signals.
The terminal shows the rubbish it gets from the remote so I think it could work.
Also the Rx led lights when the Ampy led does when connected to a terminal.
Unfortunately I can't let it respond to commands like /?! in the terminal, maybe some settings or coding is wrong.
From this topic I understand that the Ampy 5227 sends with 4800bd. (/AMP45227-0614)
If I get this working it is a very cheap solution, the pcb is only $10 on Ebay with free shipping.
