Sharky 775 Diehl #145

Closed josvandekoffie closed 5 years ago

josvandekoffie commented 5 years ago

Hello great programmer, I use Mbus for the Sharky but somehow sometimes I have a 1500 in front of power and differential temperature number. This happens especially when the power read out is close to zero I think because the differential temperature and poweroutput have the problem at the same moments in time. In the graphs on Domoticz this shows as huge spikes. Curious if someone can solve this puzzle. Maybe the 15-- part needs to be a minus sign or so?

System: Mbus master (usb version AliXpress) Sharky 775 Raspberry Pi 3

Installation: https://github.com/rscada/libmbus/archive/master.zip

Okay, could you please provide a hexdump of a good case telegram?

josvandekoffie commented 5 years ago

Here is one just freshly baked. If I perform the data request twice I directly get an error. See at the bottom. Don't know if this has anything to do with it though.

@josvandekoffie Could you please test branch negative-bcd?

josvandekoffie commented 5 years ago

Hi, just installed the libmbus-negative-bcd.zip. I will let it run for a day to see how it goes!

josvandekoffie commented 5 years ago

Good evening! Just wanted to let you know: It works perfectly with the negative-bcd branch! Thank you so much!

lategoodbye commented 5 years ago

I've merged the branch into master.
