Lee, I’ll say the presenter of the program yesterday doesn’t seem to mind my continual questions so this morning he sent me this.
Is this something completely different than using the “guest” side of the router? Is it a bear to set up? You know anything about it? I’m also very grateful for your allowing all the questions going your way as well. John Jim’s reply: If you are concerned about the thermostats, you can absolutely segment your network and add a VLAN for the thermostats that only allows them access to the internet with a 1 way trust that will allow you access to the thermostats but won’t allow traffic to be initiated from the thermostats into the rest of your network. > On Mar 7, 2019, at 10:05 PM, Lee Larson <[email protected]> wrote: > > On Mar 7, 2019, at 5:06 PM, John Robinson <[email protected] > <mailto:[email protected]>> wrote: > >> Those of you that have sweet dreams of these things, what can I do, and the >> next person that has to install a new HVAC system with a smart thermostat? > > > There are many different things you can do, but I’ll tell you what I’ve been > doing for the last few years.
