2) How to setup

Firstly, setup your Petkit mobile app.

Goto App Store, download Petkit mobile app, register, login, add device. before use this plugin you MUST make sure the app works fine with you.

• for China mainland users, download “小佩宠物”
• for those Asia users outside China mainland, you should download "PetKit(International)"
• for users not from Asia, like America, Europe, etc. you also should download "PetKit(International)", but the API url address may not the same, this plugin may or may not works with you, if you are experienced in network, you could use "Quantumult X" to capture app network records, submit the api address to me or just create a PR or just modify this plugin for your own.

Secondly, prepare to capture Petkit app http request.

Please goto this wiki page to find more detail.

Finally, retrieve infomation.

you should provide one critical infomation to this plugin: X-Session, if you have more than one Petkit feeder mini device, then you should alse provide deviceId in the header field of the config.json file.

Be aware of that, to minimize the effect to the Petkit server with unnecessary http requests, the plugin just update device status more than 10s interval, which means the status will bufferd at lease 10s.

• X-Session: this value will change every time you login you Petkit app, so do not logoff your Petkit app unless necessary.
• deviceId: this value indicate which device you wanna to control. If you just have one Petkit feeder mini, you can ignore this value.

here is a example of Quantumult X capture data page:
