Hello,

We are trying to build Client to read information from meters using an Arduino and Optical IR probe. Do you have any Guide (based on Arduino), or suggestions we can follow?

kind regards

Hi,

Thanks a lot for the response. Yes, I figured there might be a memory issue which was why I tried following the raspberry pi example on your twitter page here( https://twitter.com/guruxorg/status/1164488658755444737 ), but I was unable to get a response from the device. The response i got is shown in the image attached. So i have two questions.

1. what could be the cause of this error, since everything installed correctly.
2. Can you recommend an Energy meter and Optical Probe(probably a vendor) that works seamlessly with the example?

Your response will be highly appreciated

Hi,

The reason for this is that the meter didn't reply. One of your settings might be wrong or your connection settings are wrong.

Do you know what baud rate your meter is using? Do you try to connect using optical probe (head) or serial port connection?

Hi Mikko,

Thanks for the quick response.

I thought so too but was not sure what.

I connected to the meter using an optical probe head which is connected to the Pi via one of the Pi's usb port. not sure of the meter's baud rate. It's an hexing HXE310-KP

Hi,

Try to run your app with -i parameter.

Hi,

I did. but got the same response I got running the app without it. Can you share the full command?

Hi,

Can you try to read your meter with GXDLMSDirector first? If one of the settings is wrong connection fails. What optical probe you are using? This should work if your optical probe is working.

python main.py -P YOUR_SERIAL_PORT -i
