What is a Cheap Thermostat?

In this category below I only considered cheap and affordable thermostats. I list some of the best devices which are priced reasonably.

What Will Be Missing In A Cheap Thermostat

It’s a million-dollar question, when you are paying more for Google Nest, Honeywell, Ecobee or Emerson Sensi you are getting some extra features against the higher price tag. I try my best to figure out the main differences between most advance and cheap thermostat, some of them are:

  • Inexpensive thermostats are not good learners; not made to learn the schedules and routines
  • Room Sensor Support not provided in cheap thermostats
  • Home assistant is missing or poorly designed 
  • A most simple and straight forward app that lacks in many areas
  • Inexpensive thermostats look traditional, not futuristic 

Hundreds of products are available below 100$, but we listed below a few of them which are successful, and customers are happy with them and offering similar benefits of costly thermostats. we recently reviewed the best smart thermostat for multiple zones and top-rated thermostats which are hot selling items nowadays. Let’s move to the list of affordable products:
