Honeywell Home RedLINK to Internet Gateway and Ethernet Cable and Power Cord (THM6000R7001), White

Redlink for Honeywell thermostat on my heat pump. Works well, set up is not straight forward and I was successful after following a Utube video. Probably could have called the help line but did not. I can now operate my Heatpump from a different country and can raise / lower temp easily, remotely. Biggest issue is Honeywell app as it seems to be set for only 1 location I have 3 different locations in 2 countries and had to learn to label each thermostat on the laptop site before using the app. Product is solid and works as expected

I currently have a zoned HVAC system with three main units and 8 zones, each using a Honeywell T9- which I can control via the Resideo app. I had a 9th zone installed to cover a loft space that was always quite warm in the summer. Unfortunately, I did not have enough wire in a wire run to allow for another wired T9 thermostat. The technician installed a Honeywell wireless thermostat that interfaces with an EIM (Equipment Interface Module). The thermostat worked great but I was not able to connect it to the Resideo app. Enter the Redlink gateway! In just a few minutes, I was able to connect it to one of my network switches and to power- and then sync it to the EIM. Finally, I enrolled it onto the MyTotalConnect app and then port it over to the Resideo App. Success- I can now control all 9 thermostats on the app seamlessly. And honestly it was not that difficult to set up. Highly recommend for anyone looking to set up a system with similar issues.

I was surprised at how easy it is to set up this device. I had it hooked up and working in less than five minutes, including unpacking it from the shipping container. Another nice surprise is that it works with Alexa! Setting my thermostat is now very convenient, and I can control it from anywhere in the world where I have Internet access. An excellent product!

EDIT - Feb 2020: The connection problems seem to have gone away without me making any changes. I believe the cloud services were not reliable for a few weeks then were fixed sometime in early Feb. Updating to 4 * as the service is not 100% reliable but seems to have been stable since early Feb. I wouldn't want to rely on this for a distant property temperature control but a home you live in it should be fine as you can always control from the actual thermostat.EDIT - Jan 2020. I have been having a LOT of trouble with my gateway not being able to stay connected . I received another gateway from Honeywell under warranty and it does the same exact thing. I believe what is happening is it cannot ping the cloud servers, and will go into an endless loop of trying to get a new DHCP address. I can see it re-trying endlessly to DHCP Discover, but it never ACKs the IP the router gives it. I think this is some kind of "Back-off" timer that is in the software in the gateway. Will try again to resolve this with Honeywell, as it's obviously not the hardware of the "Bad" gateway they sent a replacement for. I will update this review with details.--- Original Review ---Small device and just plugs right into network port and power wall wart. Easy to pair with the thermostat if you do a little bit of research on how to get the installer password or download the Installer Guide for the thermostat you're using. Highly recommend to do this before attempting to install this gateway. I had already paired a Red link Outdoor sensor to my thermostat so I was familiar with the process. Once it's paired you can create your account with the Honeywell site, and after that, the app is usable. There is a little bit of a lag time between "submit" button being pushed on the app, and the real thermostat actually changing. Nothing major, just be aware it may be a few seconds. This is very useful if you want to turn on your AC or heat when away from home , or monitor the status of the system. In my opinion it's safer than a Nest as it will work as a standalone thermostat without any Internet connection.

OK, that was COOL! We have a second home where we installed a new Carrier Furnace. We opted for a wifi thermostat from Carrier, and have loved the ability to control from another state. Ever since we installed, I wanted one for our primary home too. But didn't want to buy 2 new Honeywell WiFi thermostats (what I thought needed to be done).After asking my HVAC person about some ability to upgrade to WiFi, he incorrectly told me I had to buy new thermostats (@ $150/each). He was just a service guy but he really should of been able to tell me. :(So I did some further research, and a quick contact to Honeywell, they confirmed my hunch. All I needed to do is add the Internet Gateway to my system...that's it! So, for less than $100, I was able to make both of my thermostats WiFi! It only took about 10 minutes to get it all sync'd together and I got to say, Awesome!I am so happy I can now remotely control my home without spending tons of money to get it accomplished! And the App, which is really the main thing, is very nice! I get the ability to compare their interface with the Carrier one. I do really like the Honeywell much better than the Carrier one. Both systems do the same, but the Honeywell is much more seamless. The Carrier had a lot of issues initially and had to go through some growing pains. It is much more stable now.Although I've only used the Honeywell for a week or so, it really has performed wonderfully. A lot more info is available too, and the aesthetics are nicer too. Definitely very happy with the system! Also, kudos to Honeywell for responding to my questions over the weekend and a follow up answer on Sunday! I would not of expected that excellent customer service!
