Please can anyone help.

After a while pimatic 0.9 stops. After a reset he works again fo 2 or 3 day`s.
i send and receive with a arduino nano. I changed the arduino and powersupply.
The raspberry pi runs PRETTY_NAME="Raspbian GNU/Linux 8 (jessie)"
NAME="Raspbian GNU/Linux"
VERSION_ID="8"
VERSION="8 (jessie)"
This a error report before the crash

error [pimatic]: A uncaught exception occured: TypeError: Cannot read property ‘length’ of undefined
at Function.Buffer.concat (buffer.js:289:24)
at afterRead (/home/pi/pimatic-app/node_modules/pimatic-homeduino/node_modules/homeduino/node_modules/serialport/serialport.js:369:36)

at FSReqWrap.wrapper [as oncomplete] (fs.js:576:17)
This is most probably a bug in pimatic or in a module, please report it!

I also have a pimatic v0.8 who works continue
