To control your Honeywell thermostat remotely through the internet, you must run through these Honeywell WiFi thermostat registration instructions. Furthermore, you do this at the Honeywell Total Connect Comfort (TCC) web site. So here, we walk you through that on the RTH9580WF smart thermostat.
Honeywell WiFi Thermostat Registration Instructions: First Steps
1. Install your Honeywell WiFi Thermostat
Firstly, skip this step if your thermostat is up and running, and showing its home screen. If it isn’t, then see our Honeywell Smart Thermostat Wiring Instructions RTH9580WF post. So this gives tips on mounting and wiring this new thermostat.
2. Connect your T-stat to your WiFi Network with Internet Access
Skip this step if you’ve already connected your thermostat to an internet-ready Wi-Fi network at its installed location. If you haven’t, then see our Change WiFi Network on Honeywell Smart Thermostat RTH9580WF piece for instructions. That post details how to link your thermostat to your home or office wireless network.
3. Create an Account on the TCC Web Site Honeywell WiFi Thermostat Registration
You’ll need a working account over there in order to register your thermostat and control it remotely. Again, skip this step if you’ve already set up a TCC account. If you have not, then visit the TCC web site here. Then on the login page, click the Create an Account button, and then follow the instructions.
4. Gather Thermostat Info
To add your thermostat to your TCC account, you need its MAC address and CRC code. They print these in the documentation that accompanies new Honeywell thermostats. However, you may also get them from the thermostat itself, as follows. If you have this information already, then skip ahead to Step 5 below.

Note that we connect the thermostat to our 937T681J4059H_2G wireless network. However nonetheless, it is as of yet, unregistered. You should have connected yours to the network you used in Prerequisite Step 2 above.
