Hello everyone,

I’ve installed the Homey Hikvision AX Pro Alarm (v1.1.7) app and was able to discover my panel and door contacts succesfully. But when I try to ARM or DisArm I’m getting:  
PUT /ISAPI/SecurityCP/control/arm/3?ways=away a 404 error

I’ve tried in the browser (after authentication):  
http:///ISAPI/SecurityCP/control/arm/3?ways=away  
Error:  
  
/ISAPI/SecurityCP/control/arm/3  
4  
Invalid Operation  
methodNotAllowed  
1073741828  
methodNotAllowed

Has anyone seen this before?

Model: DS-PWA96-M-WE  
Device Version: V1.3.1 build 251113

Hi Goose, thanks for the precise report. Your panel’s firmware (V1.3.1 build 251113) only accepts the arm command in its JSON form (…?ways=away&format=json) and answers the plain URL with 404 methodNotAllowed, which is why disarm worked but arm did not. This is fixed in v1.8.0, uploaded to the App Store today. Please update when it appears and let me know if arm/disarm works on your panel.
