The Wyzecam should support multiple continuous timelapses. At least 2 are required.
Use case: My wyzecam is pointed outside from my garage to my driveway and I want to capture the change of the seasons. For this I might want to set a long term timelapse, taking 1 picture every 12 hours for 6 months. I would also still like to be able to take a short term timelapse of something else (for example me cleaning snow from the driveway for 2 hours) without disturbing the long term timelapse.
Buy a second Wyze cam because they are inexpensive (edit/ inexpensive, not cheap ) and mount it next to the other one. Use one for long term and the other for short term. Use the daisy chain way of powering, just use a higher amp power brick and away you go. I kinda doubt the hardware of the current Wyze cams will be able to support this, along with all the other services and features they currently have.
That’s my approach.
Also means I’ve “spare” cams I can use for special purposes, recording trick or treaters, putting an “eyeball” on something that needs monitoring, like watching the barbecue for my thanksgiving turkey, etc.
A V2 or Pan with a $16 10AH powerbank makes a portable “eyeball” and will run for about 20 hours.
Or you could just run the short term for a long time and subset the video with other software.
/edit - note - presently your limited to about a month.
After reading about your experiences and uses for the power bank equipped cameras I made one! It’s actually rather handy. I now have a Turkey Cam for keeping an eye when we bake the turkey. And I also deployed one to keep an eye on a long 3D print job I was doing, another time I had it watch my computer screen during some long running tests and compile jobs. The uses keep multiplying!
Also bought 2 to play with, one to disassemble just to see. One to play with alternate firmware with. Both activities can easily result in a small cute paperweight so be careful if you do the same.
