  1. My thermostats frequently fall off the network, what can I do to help prevent this?

 

The thermostats communicate at 10 Megabits per second (10Mbps) Half Duplex so can get blocked by higher network traffic, causing them to fall off the network. Frequently seen when video/surveillance cameras, or other devices on the network, that create allot of network traffic. Try to isolate the thermostats to so they only receive the network traffic that is meant for them.

Some options are:

  1. A) Use a Managed Switch for the thermostats
  2. B) Connect the thermostats to their own router
  3. C) Create a VLAN environment to logically isolate the thermostats on the network
