Have used a Sensor for over a year. Got message that the battery needs to be replaced. Replaced the battery, and now it continues to fail the connection test. Deleted Sensor from account, re-added without any issue, then try the Connection as part of the setup, and it just fails. Even had the sensor 1 foot away from the thermostat. What are my next steps? I've read a fix that basically removes everything Nest in your house/phone/etc. But I find this to be sensless. I just replace a battery.
I too have had this happen. I have THREE sensors connected to my stat. ALL of them show offline. Tried remove/reinstall in app, no change. Doesn't CONNECT to the stat. Batteries are GOOD, distance is within reach. I think its the stat, not the sensors. SERIOUSLY considering returning it all to Amazon and going with a diff company.
Just got off phone with support. RESTARTing the T-stat resolved the issue. I've had this stat and 3 sensors less than a month. If this happens again in the next 2 weeks, back to Amazon it all goes.
Push the thermostat dial towards the wall twice.
Then, choose the gear icon (settings) by rotating the dial.
The last option is restart.
However, that didn't work for me. Ready my sensor reset instructions on this thread. Those worked.
Trying the Thermostat Restart didn't work for me. However, what worked for me was removing the sensor battery and shorting the sensor battery terminals for a few seconds to discharge any caps inside the sensor. Then, put the sensor battery back in. Check the connection with the app and it connected right away.
Thanks for this tip! This totally fixed the problem using a paperclip to discharge the capacitor! I was getting ready to throw the Sensors against the wall after trying to reconnect them for weeks.
This is amazing it worked perfectly and instantly. Not just once but then i had a sensor that hasn't connected for YEARS that i spent weeks going back and forth with the google help team and they couldn’t do anything helpful and wanted me to start a whole new nest account and set up all my cameras and thermostats again. I said no thanks and gave up. I tried this on that sensor and it worked too! Unreal. Google please adopt this step as part of your formal troubleshooting because it is way quicker and more effective than having the user reset everything in site just to try again in vain.
Thanks for the tip! I just had this exact problem after changing the battery in my Nest Temperature Sensor. I took the battery out, and I bent a small paperclip to connect the two terminals for about 5-seconds. The sensor connected right away once I re-installed the new battery. Worked like a charm!
Thank you so much for the paper clip trick! I've had a "dead" sensor for months and I've worked with support multiple times with no help from them. I was about ready to break down and buy an Ecobee since Google wanted me to remove all my devices and set everything up everything up again to fix the sensor. Why are they not recommending this step? It fixed my problem instantly, and you don't get shocked or anything.
