Graphite writer booleans are not parsed correctly

[janvonde]

First of all thanks for this great application. I use it to query data from my CCU2 and send it to an influxdb for evaluation in a Graphana dashboard.

I have the problem though, that booleans are often not parsed correctly and sent as string to the influxdb which results in error messages like this:

Is it a problem on my side or can you fix it in the code?
