AVTech Roomalert 32E - issues polling and drawing graphs

Observium Professional 22.5.12014

I have an AVTech Roomalert 32 that's up to date with vendor firmware (3.3.1). It has 6 temp/humidity probes conncected on ports 1-6 and two temp probes connected on 7-8. It also has an internal temp/humidity sensor. These are all reporting correctly according to the device's built in monitoring interface.

Experiencing following issues:

• Obs does not know about software version
• Obs is aware of temp/humidity sensors 1 through 6, but is only drawing graphs for a couple of them. In the graph legends the value data for the missing entries is listed as 'NaN'.
• Obs is not aware of sensors 7-8 at all.

I've filed this as vendor bug as I'm toelrably certain they're not doing SNMP right, but if you could check I'd be very grateful.
