Hi  @Solla-topee, thank you for your reply

1. Currently, what's the Trigger and Action you have configured on the Alexa app and IFTTT app?

 - Alexa: trigger: motion detection(Tapo C200)

 - IFTTT: trigger: motion detection (all Tapo models)

2. What Trigger and Action do you want to configure on the Alexa app and IFTTT app?

- Alexa: trigger motion detection in models C310 and C100, besides "person detection"

 - IFTTT: trigger: motion detection without having the notifications turned on in the Tapo app. (all Tapo models)

A person from tplink support just responded in the ticket:

For IFTTT need to open notification permission in Tapo APP, it may be due to the different mechanism of triggering motion detection in different three-party software.

As for the lack of motion detection option for C310 and C100 in Alexa, I just tested it and there is indeed no motion detection option, only person detection, probably because these two models do not support motion detection in Alexa APP. So we are unable to change the Alexa Tapo Skill.

but Alexa's support claimed to be a Tapo Skill (for Alexa) limitation rather than an Alexa App limitation.

Thanks in advance.

  @Solla-topee thank you so much for your time and for logging it. I hope we can get that capability in the near future since all the hardware is reafy (and it's even working already with IFTTT) 😄
