Venstar T7850 Colortouch 7 Day Programmable Thermostat with Built in Wifi (Replaces T5900 and Acc0454)

Great product, easy to install

Just what I was looking for to continue weening my smart home off of Silicon Valley. Connects seamlessly with Home Assistant, meaning I can control the temperature without going through third-party servers. The only complaint I have is I still had to register an account just to use network time. NTP is an open protocol. There should be no reason to create any account on any external service.

I purchased the Venstar T7850 Colortouch in November for use in my vacation home. After installing it I found the thermostat had a problem and did not communicate with their cell phone app. I contacted Venstar support and explained the problem and even included pictures from the thermostat, but they never replied to my email. As a last resort I contacted Amazon Support. They immediately replied telling me to return the thermostat to them for testing. Within a week I got a reply that a replacement was being shipped. The replacement thermostat worked perfectly as advertised. It's really handy to check the temperature of a home 200 miles away and know the furnace is working. Last week I used the app to turn the temperature up (the vacation home is in Northern Michigan) so it was warm and comfy when I arrived. A big THANK YOU to AMAZON for their fast and helpful support!

This is an excellent wifi thermostat I love the touch screen full keyboard and full screen instructions. Much easier to program than my previous Nest plus shows both the room temp and the cooling and heating set point. I also love being able to show pictures of my kids and send messages directly to my wife such as "running a little late tonight. I have only 4 wires but installed a extra wire devise and it works great.

This works fantastic for my needs. I have it linked with Alexa and to my smart phone via WiFi which is built in. Not external card needed (only for pics). I can use it remotely and/or the touchscreen. I’ve had one for many years, way before Alexa and have loved it. Just had the older model. I love how it was the same size and clipped right onto the old base.

Straighten things out with the seller waiting for a new item misunderstanding

I got this because I didn't like the nest was sold to google. I want something that is local only. My issue with this is that the temperature seems off. I have to set it off a bit from what the readout says. I do like the programming. It makes it easy to avoid the peak electricity ours for running.

Fairly easy to self install and setup. Accurate temperature on duel fuel heating system. Can email alerts, and can be set with app or web access.
