Wasted huge $ to set up whole house,7 zones, on system. Have to now throw it away. DONT BUY!!!!!$ ### 1/5 — Obviously an afterthought *2022-02-26, version 1.303* The setup doesn’t work. The screens don’t match the screenshots in the manual. There is no “Connect to Wifi” button! The installer says I must talk to hbx. No one answers their support line. After flailing for hours it somehow connected to my wifi but the app constantly disconnects from THEIR servers and I’m unable to use it to control my thermostats. It’s useless. There is no hardwired option. ### 1/5 — Poorly Functions *2021-11-27, version 1.303* The app is awful. Constantly disconnects from the system. To make the simple changes takes hours. So frustrating!!! ### 3/5 — Works, but could be better! *2020-10-23, version 1.302* Please add features that allow you to see snow rate, push notifications for when a boiler turns on. And push notifications for when the boiler turns off. ### 1/5 — Awful *2020-08-04, version 1.298* Hard to give a review for an app that controls thermostats after they have been installed, but if you’re researching, don’t get these thermostats. Looses connection constantly with the server. Thermostats magically change temps with no input. Have to start the app, then close it and re-open it. Setup took me 8 hrs of my time with a rep on the phone! Maybe I have bad thermostats...(6 total) all I know is my app is awful. ### 5/5 — Controls Geek *2017-03-17, version 1.05* First of all, I have used many different controls over my career and many fall short or disappear over time. I have used most of their controls now and I have not been disappointed! This APP offers so much more than the other Consumer Stats could ever as well as the Blue Box Guys! This is a professional contractor grade system with all the features (floor sensor comes standard) but with much more behind the scenes (advanced settings). I wish I knew about them sooner. If you have an CCN Control made by Uponor, HBX's 2 wire thermostats and ZON-0550 may be the closest thing out there to retrofit, their THM-0550 should be a pretty good option! These controls offer so much, yet are very intuitive. This APP makes controlling Snow/Ice Melt Systems and controlling the thermostats simple, there is nothing like it in the market!!!! The advanced setting really make reviewing and changing settings easy. I just installed a system using their new Touch Screen THM-0500, amazing!!! Contractors - HBX is committed to growing your business, get to know them, you won't be disappointed! ### 5/5 — Great product *2016-01-18, version 1.00* Easy to install and get started - I'm impressed so far. The app really compliments the system in my house. I love how easy it is to use. ### 5/5 — Works great! *2015-12-25, version 1.00* Perfect solution to WiFi zoning for great price! ### 5/5 — User *2015-12-23, version 1.00* Great app. Great thermostat. Great company. ## Frequently asked questions about ThermoLinx ### What HBX hardware is required to use ThermoLinx?
