My Nest E thermostat has shown the dreaded W5 error today. All my research is saying the Wi-Fi chip is fried and its a well known issue with Nest thermostats.

It has only lasted me 6 months and from a Home Assistant standpoint has been a bit infuriating as it constantly needs reintegration.

The plus side is that it cost me a grand total of £15 off a charity shop on eBay that was selling it for spares and repairs because the display was “dead” but actually just needed a good charge. I saw from my research that this has happened to a lot of people who actually paid full price for it, and replacements are only sent out if it’s in warranty.

It still works as a thermostat but ain’t smart no more! I’ll have to start trawling ebay for a cheap replacement display.

Nothing else to say, I’ve been starved of social media this week, going cold turkey from the R word, so that’s what this is really.

    Have you checked to see if your state has some sort of energy program to get a smart thermostat at a discount? I got our Ecobee for $20 through our states program and it works pretty well with Home Assistant
