Original Smart Sense Motion Sensor will not connect

I have the original Smart Sense Motion Sensor that I used to use at the front door. When the battery died I was too lazy to change them. However, after a year of not using it I decided to use it inside the house. I have opened it open and pressed the button for six seconds and then tried to connect it to smartthings, it still won’t connect. I have tried everything I can think of. If anyone has any suggestions please let me know.

Thanks

Have you tried plugging it in to an outlet? Those had the micro USB power option

Yes I have tried using the USB as well. Same result. I hold the button until the red light turns off. Then I press it once and it flashes red and nothing happens.

Contact support if you can’t factory reset it
