I've been going back and forth with tp-link support on this issue now for about a month. I've had the HS200 and a LB130 on a sunrise off -  sunset on schedule for about 2 years working perfectly. In the past couple months I noticed that they both stopped turning off at sunset in the past 2 moths or so. I updated the location settings and actually deleted both devices and re added them and the LB130 successfully turns off at sunrise. But the HS200 will not shut off using the sunrise off or even setting a specifc time. Both turn on at sunrise. 

1. I've even reset the the switch and started from scratch. No change
2. I've deleted the schedule and added a new one. No change
3. I've disabled the schedules and added them in Alexa as a routine with both a time and or sunrise off. No change
4. I've uninstalled the app and installed the developer app and , No change
5. The LB130 works fine though either way. 

HS200 will not respond to turning off with any schedule.

Anyone else have this issue and if so, have you been able to fix it and if so how did you resolve it. 

I've been going back and forth with tech support in emails for about a month or so with no luck.
