So I have a bit of a brain fart here/head scratcher:
Running HA on 2023.2.5, with ESPHome soon to be at 2023.2, and I really wanted to do something at my desk at work. So I subscribe to NabuCasa so i have the Nabu remote URL, and a bunch of esp32s on my local network doing different things, but I built a tiny display for quickie looks at vital values i want to keep a eye on. I would really love to put it on my desk at work, and have the ability to at a quick glance make sure my ha is good and a few other values, and maybe set up a BLE proxy to detect when im at my desk(but now im crazy) Has anyone done something similar? Plus factor if I can also remotely manage the esp32 from ESPHome.
The Nabu Casa based remote access only provides access to the web UI of your Home Assistant instance at home. It does not support connecting ESPHome devices outside of your home network.
The connection between your HA server and the ESPHome device is established from the server to the device. So, for your scenario to work the ESP would need a public IP address routed through your corporate network (I doubt that would fly with any organisation), or you would need to somehow connect the ESP via a VPN into your home network (which would require a VPN capable PC at work with a WiFi adapter for your ESP to connect to, and a VPN server at home, and of course your organisation to even allow an outgoing VPN connection through their network).
The next best thing I can think about for your use-case (assuming your organisation allows BYOD on their WiFi) is to find an old smart phone, build a dashboard for the screen size with the most important sensors, and connect that through the remote UI via Nabu Casa.
