On installing the E1 Pro using the app but keeping it private: I was able to install the E1 Pro on a private subnet, by keeping the app on the same subnet and never “crossing the streams”, so to speak. It was a pain, but possible.
The places you can run the app:
- on an Android phone, connected via USB ethernet dongle to the private subnet
- on a Chromebook/Chrome OS, which allows running Android apps, also using a USB ethernet dongle
- on Android running in a Virtual Machine, such as on Proxmox
The first two options are the most convenient, but are not great in terms of maintenance. The third option is harder to set up, but allows such things as remote administration. It’s an okay option if you’re already running VMs.
I wrote up the third option here: Running the Reolink App in a virtual machine on a private subnet
