I'm setting up a system to monitor lots of different sensors in a building (90+). lots of them are analog and lots of them are digital. It is going to a different system in each building(lots of buildings).

I need to read in thermostats, HVAC unit monitoring, Generators, etc...

I am looking for something similar to what I found here:
http://www.perle.com/products/Ethernet-IO-Device-Server.shtml"

but it would be too expensive to buy thousands of these. THOUGHTS?

The information can be sent via tcp/ip, rs232 or something similar

You can check out the module and network offerings here:

They carry a number of network sensor solutions.

[Full Disclosure] They carry some of the products that my company helps to design [/Full Disclosure]
