Rated 1 out of 5 by from Great til it breaks Had two of these now one a replacement for the first. They have a common issue of wifi chips failing which leaves you with a rather expensive non smart thermostat. Search google for Nest w5 error

Rated 3 out of 5 by from Good thermostat - WIFI issue! This is a fantastic thermostat it does work and the app is great full control of the boiler from wherever you are. Probably the simplest in the market to operate too, great overall device. However all these 3rd generation have the same problem with Wifi Loss( see youtube failed videos), mine dropped after 3 months so it would not connect to the internet at all or find any network. Google will replace the head no questions asked however I was a bit concerned the customer assistant was recommending me the advance model. I hope the new one does not break down again in three months. I won't install it in any rental accommodation as it's probably going to fail again. Hope they fix this hardware issue soon as it is such a fantastic thermostat.

Rated 1 out of 5 by from Burn's out Wifi Chip After 18 month of seamless use, the Nest just stopped working one day with no reason. We diagnosed a burned out Wifi chip, which Nest/Google Verified. Nest are sending a free placement. However over 1000 users in the UK have had this happen since the start of 2020 (6,000 globally according to Google). This is a software glitch that Nest cannot seem to fix (despite trying for 2 years). So the chip could burn out again. If it does I will return the unit to Screwfix for a refund. If you want a reliable home heating thermostat I would buy a Hive. We have one of these on another property and it has worked faultlessly for 5yrs+.

Asked by: Piyu

Hi -i have a seperate hot water tank from my boiler which my current programmer also controls -will this also control this? I have also read through the questions that someone says the usb is not included to power it if you buy the silver one, is this tru

Asked by: Jmacl
Nest Thermostat E is not compatible with your system, but our other thermostat, Nest Learning Thermostat is compatible with it. While all Nest thermostats have a USB port for charging when needed in rare cases, the internal battery of Nest Thermostat E gets its power from your system wires. However, the charging cable isn't included in the box. You'll need a micro-USB (USB-B) to USB-A cable for Nest Thermostat E and Nest Learning Thermostat.

can I power the nest from a USB output

Asked by: prohandling
Unfortunately, you can't. Nest Learning thermostat requires an input of 20-30V AC to operate properly.

Battery Power

Does the thermostat have batteries installed? If so, are they rechargeable and how long do they last after removing the thermostat from the stand?
Asked by: GeorgeBT
Yes, it has a built-in rechargeable Lithium-ion battery. While it's hard to say how long the thermostat display will last with a fully charged battery, it has enough capacity to keep working for a while if it's removed from the base since it will only supply power to the digital display.

does the Nest Thermostat operate on a 230 volt switching?

Asked by: SPEAR9
Nest Learning Thermostat can only operate on a 20-30V AC system. You can find more information here: https://support.google.com/googlenest/answer/9230098?hl=en
