Can't get Kaifa meter to work. #6

Closed rewolff closed 8 years ago

rewolff commented 8 years ago

Got a new meter friday, however I can't get this to work. Every time I fix something the next thing pops up. My meter is the latest protocol version, so runs at 115200 baud. Similarly, if the meter isn't on /dev/ttyUSB0, the program is a hassle to use if that cannot be configured but has to be provided on each commandline.

I got it so far as to start parsing stuff but then when it tried to convert stuff to kwh by multiplying by 1000, I get a "nonetype" that cannot be multiplied. This means that the error is somewhere else and my python is iinsufficient to trace where things go wrong.

Here is a message from my meter to aid in further debugging. smartmeter.txt I've blacked out some serial numbers as I've seen others do. The x's represent digits, their number is correct.

Hi rewolff,

Thanks for providing sample output. As soon as I am near a workstation I will do some troubleshooting.

Note that I have a "Kaifa" and that there is still a pull request open said to improve things for a kaifa. I have the 105C, where the C denotes the latest version with 115k2 serial and latest updates to the protocol. (IIRC, some units were adjusted from Wh to kWh. things like that).

@rewolff I have just merged to pull requests into master and created a new tag and published it here

https://pypi.python.org/pypi/smeterd/2.4.0

Can you try now?

Reading the telegram, I think a some of @rewolff s issues are resolved in #8 (reading the gas meter) The parsing of the kWh is a localization issue I think. Our meters seem to have a . for decimal seperator and this is interpreted as a thousand separator, but i'd have to investigate that and make a separate issue.
