Sorry about the Factor in my first version. I first hacked the host template file together, then returned to this forum and was reminded about the preference for SI units in the thread about DELL UPS host template.
Included with this message is a fixed host template which no longer relies on Factor to fix the scaling.
Even though I have added some host template files to this forum I must admit that I am no expert in template writing. I would not be able to write a new host template from scratch without heavy consulting of documentation. Instead my method of writing or modifying templates usually are: copy and paste from something similar and then more or less random hacking with trial and error until the template behaves as expected.
