The Google nest thermostat lost display and gets fairly hot.I contacted Google nest customer support who stated they would have loved to have helped me but the warranty has run out.2 year warranty for a product that is only used for 6 months out of every year for 2 years is rubbish to be told that I have to buy another unit is bad.These thermostats are rubbish,get a hive product instead(and I am a heating engineer!)Absolutely terrible product.
