Also don’t have UUID and not sure want to share in public post. Is there more secure way to communicate?

@Scott12 Please offer SN or Bluetooth Mac.

SN is ok. Please keep your lock connected to WiFi, then i will push the firmware.

Can’t update since I only have modern WiFi (5GHz)

How can i make sure both my locks can get this update?

Hi, can you share me the router purchase link? thanks. @Brine Also, how long can the batteries been used?

Hi Carrie,
The router is provided by my isp.
Is there some info I can get from the eero app for you?

Are there plans to resolve the issues mentioned in this thread: Auto lock not working when manually unlocked - #58 by Vaibhav? Or at least acknowledge them and give us an update?

I have tried to update to this firmware version 3 times and received an error each time.
