Upgrading Nest Learning Thermostat: 2nd Gen to 3rd/4th Gen

[bixieupnorth]

as much as i hate to have to fork out to replace a perfectly good, working 2nd gen, it looks like my hand is going to be forced.

uk based.

my current set up is a 2nd gen on a cradle/base, in the living room, connected via wifi to the heat link in a cupboard in the hall where the boiler is.

i can't find any guide to tell me if i'd simply have to rewire the cradle for the new nest thermostat, or whether the heat link itself would need rewiring? 

if it's the cradle then this appears to be a simple job that a buffoon like me could manage. anything else would need an electrican or boiler engineer i assume.

thanks in advance and a big boo to google for abandoning us.

Similar position. I have a mk2 and a mk3 Nest Thermostat. Thx Google for gradually killing off the Nest range. Still by far the most beautifully designed thermostat out there - but no, not for the EU or UK. You can swap it for a Tado instead. 

So my decision is - do I buy up one of the last mk3 thermostats to replace the mk2 - then wait a few years until Google kills that off too?  Or just replace it with a Tado - or simply do nothing. Let the mk2 carry on until October and just accept that I'll no longer be able to see it in the app. 

Not a problem I wanted to be faced with. Thx again Google. I wonder what the time scale for support is for these devices. If you were to buy a mk3 - do they then support it for the next 10 years? They could easily kill it next year, if they chose to surely. It really doesn't make one want to put money into buying things linked to Google. No about next will be all my Nest Cameras and the Smoke Protect to be axed from the app.

agreed. i'll never buy another google product from them, but would consider the 2nd hand market. just because these are such b-loody good thermostats.

mine's been flawless since i got it installed by npower in 2014. when google didn't have their greedy fingers in this particular pie!

i appreciate that it's still useable, but i'm not looking forward to hunching over it like a geriatric safecracker trying to put the various times and temperatures into it depending on what time we're getting up that week.

why abandon it? how much would it really cost them to let us stay on the app, or open source it so that some clever sort can make us our own app?

i'm still fuming every single day at them for this act of eco destruction, but do they care, do they reply? do they hell as like! BOOOOOOGLE more like!

Bought my first one in April 2014. I'd emailed them in the USA before it was even launched here to see if I could get one. I remember it appearing and seeing it - thinking Wow! I want one of those. Had to wait till it appeared in the UK stores tho. Was really sad when the Ex Apple team that ran the company for so long sold it off to Google. 

As you say - it's a shame a 3rd party can't simply setup the original Nest App to keep supporting it properly. I really cannot see that it's that hard to do. Same as not supporting the v4 version outside of the USA. Just such a shame.
