I have several TP100 smart plug, 

the schedule works for sometime then it stops doing the schedule. inalso noticed that the runtime data are all zero even if it was running for several hours. i have remove and reconfigured the snart plug several times, it will work as schedule then a some point during the week the schedules will not work any more.  If i set a new schedule it will not work or if I set a timer a network error will appear. If I turn on and off manually via app it will response.

I have the lateat firmware and latest app version.

hope you can help
