27ECLYPSE Connected Thermostat (ECY-STAT)
Client to Hotspot Configuration
Laptop 1 is connected with an Ethernet cable to a router set as a switch (Subnetwork 2). The routers
that are part of the wired network are configured, on their wireless side as a Wi-Fi Access Point (Sub-
network 1).
One ECLYPSE Thermostat is connected with a wired connection to the router set as a switch, and the
others are configured as a Wi-Fi Client and are wirelessly connected to a router set as a Wi-Fi Access
Point.
With this configuration, laptop 1 is on the same subnet as the ECY-STAT connected to the router set
as a switch (Subnetwork 2 created by the Ethernet connection), but the other Connected Thermostats
are on a different Subnet (Subnetwork 1), so the laptop 1 user only has access to the ECY-STAT on
its same subnet. This is because BACnet/IP broadcast discovery messages such as “Who-Is” do not
pass through network routers that separate subnetworks. This means that BACnet/IP controllers on
different subnetworks will not normally communicate with each other. However, the laptop 2 user has
access to all the ECLYPSE Connected Thermostats. A solution is to use BBMD on both Laptop 1 (us-
ing EC-Net for example) and on the Connected System Controller.
