Connecting a Charge 2 and a Sense to same account

[DaveFoster3029]

Hi All, 

over last three years I've been able to connect both a Charge2 and a Sense to my account. 

About a month ago the Charge2 stopped syncing. I know it is working OK as I can pair and sync with another phone (through another fitbit account). Also have same issue with a Charge4 + Charge2 (my wife's combo)

Any idea's if this caused by a Fitbit server change ? I've tried everything I know of in terms of flushing software and re-installing. It's infuriating as I was about to buy a Sense2 but I won't do it if I can't use a combo. I like to use the tracker during manual tasks (eg car restoration and house maintenance) where it's more likely to get damaged. I'll not risk a Sense or Sense 2 in my workshop.   

Should I just jump ship and get a standalone like Amazfit 2 and use the Charge 2 with Fitbit app. That way I get to track everything and just keep an eye on the numbers manually. (poor;  but best I can think of without risking the Sense in a hostile environment)

Just hoping someone can shed some light on it before I go

Sorry should add that the phones are Motorola G54 (2023 Model 5G) running Android 15

Hi @DaveFoster3029 and welcome to the community. 

I appreciate your message about using two devices in one account. 

You can't connect multiple devices that use the Fitbit Gallery to one account. For Fitbit Charge series, Fitbit Inspire series, Fitbit Luxe, Fitbit Sense series, Fitbit Versa series, and Google Pixel Watch series, only connect one of these devices to your account at a time. 

If you connect more than 1 Fitbit device to the same account, note the following:

• If you forget to take off one Fitbit device before putting on another, the overlapping data is reconciled to present the most accurate information possible. For best results, don't wear more than one device at a time and sync each device before taking it off and putting on another.
• Only one person can use a Fitbit account. When you create an account you’re asked for personal information, such as height and weight, to calculate certain data.
• If you have more than one Fitbit device that receives notifications from your phone, notifications might appear on one or more of your Fitbit devices.
• A Fitbit device can only be paired to 1 phone. If you have more than 1 phone, you only receive notifications from the phone connected to your Fitbit device.
