Web development for smart switches IoT

I have many jinvoo light switches in my house. I control them from the app in my cell or using alexa echo gen 3 and everything works perfect. Now I am trying to create a local web page that allows me to know the status and to interact with the switches.

I have been looking an api and found nothing. I also thought about creating an Alexa skill to interact with my page or to use and arduino ESP8266.

Any suggestion will be appreciated.
