Unable to discover devices? Venstar uses SSDP for it’s discovery protocol, so it needs to be run on the local network of the thermostat wifi network. If your thermostat is in another building on a different wifi network, or, your Events2HVAC server is on a different network than your thermostats, you won’t be able to discover your thermostats automatically. For the non-discovered thermostats, you will need to find the IP address and the MAC address for each one.
Here’s some Windows command line tools you can use to help locating your thermostats if you can’t find them on the network that the Events2HVAC server is hosted on. Run these commands on a PC connected to the wifi network for your thermostats.
You’ll need the IP address and MAC for a manual entry. MAC is used to uniquely identify the thermostat and also used to check if it is a static or dynamic address.
ARP
This tool will discover any IP and MAC addresses on the network you run the command on. It will also let you know if your thermostat’s IP is static or dynamic. All of your thermostats should be assigned a static address, not dynamic.

TRACERT
Trace route to an ip address
NSLOOKUP
You can use NSLOOKUP “hostname” to find the thermostat by name.
>nslookup {ip or hostname}
>for /L %N in (1,1,254) do @nslookup 192.168.1.%N >> names.txt
Loops thru all IP’s on a subnet and dumps results to a names.txt file.
