Hi @smingoli,
I am not sure whether the E1 Zoom expects the same URL string as my Reolink NVR. Try to change “SetPushV20” for “SetPush” (it seems older software versions use this). If that doesn’t work, you can use Firefox web developer tools (network tab) to get what URL is specifically used for your camera model upon toggling the PUSH switch trough the camera web interface. Do feel free to ask whether you need further help. Good luck!
