The URLs for the APIs have changed. The following should work.

[JuliusBlueTek]

curl -v -k -X POST -H "os: i" -H "Content-Type: application/json" -H "c: 338" -H "lan: en" -H "Host: mobile.proscenic.tw" -H "User-Agent: ProscenicHome/1.7.8 (iPhone; iOS 14.2.1; Scale/3.00)" -H "v: 1.7.8" -d "{\"state\":\"欧洲\",\"countryCode\":\"49\",\"appVer\":\"1.7.8\",\"type\":\"2\",\"os\":\"IOS\",\"password\":\"$(echo -n $PASSWORD | md5sum)\",\"registrationId\":\"13165ffa4eb156ac484\",\"language\":\"EN\",\"username\":\"$LOGINUSER\",\"pwd\":\"$PASSWORD\"}" "https://mobile.proscenic.tw/user/login"

The SN number can be gotten from: curl "https://mobile.proscenic.tw/user/getEquips/$LOGINUSER" -d "username=$LOGINUSER"

The rest_commands.yaml needs to be changed to ->

rest_command:

I've created a Repo for the M7 that works on Proscenic home. (It may work with other vacuums form the Proscenic Home app). That can be installed via hacks. It's still rough around the edges, but it lets you get the map view (and updates while the vacuum moves around) and do all the commands. Check it out here. Also thanks to @andker87 for the work here! It sent me down a rabbit hole I've had fun working on!
