Trying to set up the honeywell wi fi thermostat. Get error msg: Mac ID and croc numbers don't work. Pls help.

Some context might help. Was it working before but now has this error? If you're just installing it, had you connected it to your wifi and have the app running or .. That initially strikes me as an incorrect wiring error but, not sure how or when you're getting it.
You might want to give us some more detail to work with here.
Additionally, you might want to visit this Honeywell Support page for info as well. > https://www.honeywellhome.com/supportsearch?br={489B8F52-15F5-49DD-B283-40D30099A3A1}#q=Wi-Fi%207-Day%20Programmable%20Thermostat%20%28RTH6580WF%29

Let us know if this helps.

Honeywell has the manuals for most of their thermostats on their web site. Start here, https://customer.honeywell.com/en-US/Pages/Department.aspx?cat=HonECC%2520Catalog&category=Wi-Fi%2520and%2520wireless%2520models&catpath=1.2.1.4 , for the Smart thermostats.

The E43 error indicates that the thermostat can't communicate with the router. Make sure that the router can communicate with your WAN (wide area network). Check the power and that the Ethernet cable is plugged in and undamaged. Reboot the router (unplug it and wait before plugging in the power cord). If you recently changed the password or the router SSID (the name of the network that the unit uses in its communication), try resetting the internet connection. Similarly, if you have a new router, reset the connection. Make sure that you know the SSID, password and encryption for the router.

I've checked the directions to do this on the Focus Pro TH6320WF series. Press More on the thermostat for 3+ seconds until the screen displays two numbers and the button labels are Done, Back and Next. Press Next until the larger number on the left of the display shows 39. Use the Up/Down arrows to change this to 0. Press Done. Take another Wi-Fi enabled device (tablet, cell phone, laptop) and set it to look for other available networks. Find the network with Thermostat in the name and connect to that network temporarily. If you see a prompt about the type of network, call this a Home Network. Open your web browser and go to the thermostat's Wi-Fi set-up page. (If needed, navigate to http://192.168.1.1 .) Find your router's home network's name in the list of available networks. Press Rescan if the SSID is being broadcast but doesn't appear in the list. If the router does not broadcast the SSID, enter the router name in the text box. Enter the encryption mode for the router. Follow the on-screen directions and press the Connect button. Enter the router password when prompted for the information. Wait to see the Wi-Fi Setup Connection Success in the display. If it doesn't check if the password was correctly entered, including special characters.

I hope this helps. The manual for the Focus Pro thermostat is here: https://customer.honeywell.com/resources/techlit/TechLitDocuments/69-0000s/69-2736EFS.pdf .

f your thermostat either displays a no Wi-Fi icon on its screen or shows up as offline on the Lyric or Total Connect Comfort app, it is missing the connection to the Wi-Fi network.
A few preliminary things to check:

1. Does your thermostat have power? If not, check to make sure your C wire (common wire) is connected to your Honeywell thermostat. All Wi-Fi and connected thermostats (except the Lyric Round model, which can operate using Phantom Power/Power Stealing) requires a C wire to power your thermostat. Regardless of model, if you use Apple HomeKit with the thermostat, a C wire is required. If you are not sure that you have a C wire, please reference our Thermostat Wiring Compatibility page for more information.
2. Honeywell Wi-Fi thermostats are only compatible on the 2.4 GHz frequency. Newer routers can operate on multiple bands, usually 2.4 GHz and 5.0 GHz. Please check that your router is emitting on the 2.4 GHz frequency.
3. Check the distance between the thermostat and the router to ensure that the thermostat is in range of a Wi-Fi signal. A simple way to check this is by looking at the Wi-Fi signal range on a mobile device when standing near your thermostat, but note that most mobile devices usually pick up 2.4 GHz & 5.0 GHz Wi-Fi signals. In extreme cases a Wi-Fi range extender or repeater may be needed to ensure you have sufficient 2.4 GHz Wi-Fi coverage throughout your house or business.
4. Check that your router's firewall doesn't block the thermostat.

In addition, please follow the next steps:

1. Make sure your Wi-Fi router is powered and broadcasting. Restart your router by pressing the OFF/ON button or by unplugging the device from the socket for approximately 5 seconds and plugging it back in.
2. If the problem persists, please reset your thermostat. Reference your user manual for instructions on how to reset your thermostat. The manual or quick start guide will have come inside your thermostat's packaging.

Press Fan & up arrow @ the same time until you get into programming mode. download the manual & go through the numbered steps until you get to the turn wifi on & off. When you turn it on, it should show up on your computer wifi list. then program the wifi the same way you did initially with the other router.

Pull the power red wire off the thermostat and batteries out if it has battery backup, then reinstall...much like a computer restart. If this doesn't work, then replace your thermostat.

It's pretty basic actually. I've done this with Nest and Honeywell Lyric. The only thing you need to do is removing the current thermostat from the wall and connect the new one.

Set it up using your mobile application and you're good to go.

Please follow these instructions to find the MAC Address of your Android phone or tablet:

1. Press the Home button at the bottom of the phone.
2. Press the Menu button.
3. Tap Settings.
4. Tap Wireless & Networks.
5. If Wi-Fi is not already selected, tap Wi-Fi to turn it on.
6. Press the Back button.
7. Tap About Phone.
8. Tap Status.

Is there also an on/off switch for the fan on the furnace itself? If so check it make sure its set to on. Also check the on/off contacts of the switch on the t/stat to make sure its working.
