Since starting this thread, I have created a support ticket for this issue.
I received a response from a support agent, asking me to try a few things, and to provide additional info:
Make sure your Wyze app firmware is up to date.
Navigate to the Account tab > tap About.
The app version will be listed beneath the Wyze Logo.
You can compare your app version to the most up to date version listed on our Release Notes and Firmware Page.
Ensure your device (cam, plug, bulb, etc.) firmware is up to date.
Navigate to the Account tab > tap Firmware Update.
If there is an update available, please update your Wyze device.
Force close your Wyze app.
Delete the schedule and recreate it.
I had already done all of these, but did them again, and I confirmed that the app and plugs are on the most recent firmware and app version.
I was also asked:
If these steps do not resolve the issue, please send us an app log. We’ll also need to know the exact rule that isn’t working correctly, and which Wyze device is affected.
I clarified that I am not use any rules, but using the local “Schedules” option for the plug, and I uploaded the device log again.
But it has been a week, without an acknowledgment of the information that I provided as requested by support.
In addition, since that time, I have set up 4 more brand new wyze smart plugs, and set each smart plug to turn on at 7pm and off at 8pm, with each plug set to a different day of the week, from Tuesday to Friday.
Just like the first plug, all 4 of these other plugs also exhibit the same schedule issue: They all turn on and turn off at the correct time, but each plug runs the day after it is supposed to, so every plug with a local schedule is running 1 day later than the schedule is set for.
Earlier I used rules on the first plug instead of a local schedule to turn on and turn off on certain days, and the rules work fine, but I want to use local schedules which are not dependent on my internet going down or on wyze servers running, in case of internet or wyze outages (as we have experienced recently).
Can anyone else confirm whether they experience the same issue using local schedules on the wyze smart indoor plugs?
