European nest thermostat low battery

[RodriCZ]

Hello everyone,

I would like to consult something with you. I have a nest thermostat 3rd Gen in Europe. For a few years everything worked perfectly but recently my Nest thermostat would say that low battery and stop working. I would charge it with using the charger connection at the back, it would work but after 2 days or so i would again show low batter and stop working.

Could anyone give me some help please?

From your description the battery needs replacing I would think. Sounds like the battery will take charge for a short time, but sadly like all old things they do have a shelf life.

This can be done if you are happy with taking the display apart. Can be a little tricky, but to give you an idea I take about 5 minutes to remove and replace one.

Hi @Frustratedddd ! Thanks for the advice!

Hi RodriCZ,

Thank you for reaching out to the community. I'm sorry that your Nest Thermostat 3rd Gen shows a low battery message and stops working, even though you already charged it 2 days ago. I really appreciate the help, @Frustratedddd. I understand how confusing this can be. Let's work together to find a solution.

For further assistance. I need to ask a few questions:

• When was it installed?
• Do you have more than one thermostat? If yes, does the situation show up on the other thermostats too?
• Is the thermostat display on a stand?
• How do you charge it? Directly from the power outlet?
• Is there a wiring report or error message on your thermostat and/or app?
• Do you see a blinking LED light for your Nest Thermostat 3rd Gen? If so, is it red or green?
• Has there been any recent work done on your thermostat(s) or heating system? If yes, when was it?

Please keep me posted; I look forward to your response.

Regards,

Byron

Hi Byron, 

thanks for the answer. Below I post my answers to your questions 

• When was it installed? IT WAS INSTALLED IN 2018
• Do you have more than one thermostat? If yes, does the situation show up on the other thermostats too? NO, I HAVE ONLY THIS THERMOSTAT 
• Is the thermostat display on a stand? NO, IT IS FIXED ON THE WALL
• How do you charge it? Directly from the power outlet? IT USED TO CHARGE ITSELF DIRECTLY ON THE WALL (I DID NOT HAVE TO TAKE IT FROM THE WALL, I DID NOT HAVE TO DO ANYTHING), SINCE THE CHARGING ISSUE STARTED I NEED TO TAKE IT OUT FROM THE WALL AND CHARGE IT USING ONE OF THESE NORMAL PHONE CHARGERS DIRECTLY FROM A POWER OUTLET
• Is there a wiring report or error message on your thermostat and/or app? NO, BUT SINCE A FEW YEARS  I HAVE GIT THE MESSAGE THAT IT CAN NOT CONNECT TO THE WI-FI , PROBLE “W5”
• Do you see a blinking LED light for your Nest Thermostat 3rd Gen? If so, is it red or green? YES! SINCE THE POWER ISSUE STARTED IT WOULD SHOW A RED LIGHT, I WOULD THEN TAKE IT OUT FROM THE WALL AND PUT IT CHARGING ON A POWER OUTLET UNTIL IT SHOWS A GREEN LIGHT, THEN I WOULD PUT IT BACK ON THE WALL WHERE IT WOULD KEEP BLINKING GREEN FOR A DAY OR TWO, LATER IT WOULD SHOW LOW BATTERY/POWER AND BLINK RED.. STARTING THE PROCESS AGAIN 😞
• Has there been any recent work done on your thermostat(s) or heating system? If yes, when was it? NO

i would like to recall the fact that i live in Europe, my thermostat is built accordingly,

I hope this gives you a better view and thanks for the help

Hi RodriCZ,

Thank you for your response. I appreciate the detailed information. Based on your answers, please do the following:

Try to disconnect your thermostat from the Wi-Fi network for 24 hours. If the battery doesn't drain, it's probably a poor Wi-Fi connection.

Let me know how it goes and keep me posted.

Byron

Hi ByronP,

unfortunately it did not work and, yet the power drained out. What else would you recommend me to do? Thanks
