  • Browser bookmarks. My trick is I make a new folder every month, for example “2024-01 Bookmarks”, and put it in the bookmarks bar. Whenever I realize I’m leaving a tab open because I want to look at it later, I put it into the current folder. That way I know it’s not lost and I give myself permission to close it.

    When a new month comes around, I stick the previous folder in an “Archive” section and make a new one. It costs nothing to keep them forever, but avoids the current list getting out of control.













  • It’s a little confusing. Nextion makes “HMI displays”. It’s an integrated module that runs its own software, draws the UI, processes events, etc. It’s a black box that just reports back to the processor “button 3 on page 1 has been pressed”. You design the interface with that ugly Windows app and upload it to the display, but there is no direct access to the screen.

    To make use of the Nextion display, you need something connected to it, and that’s where the ESP32 comes in. It receives those “button 3 pressed” events and handles them, but crucially, it does not have raw access to the screen, so you can’t just draw your own widgets on it like you’d be able to do on an ordinary display.

    There are other projects to build your own controller with a touch screen and a microcontroller; the appeal of the NSPanel is that it’s basically an ESP32 and a Nextion display conveniently prebuilt, has decent hardware and aesthetics, and it isn’t hard to reflash it with ESPHome. Replacing the Sonoff firmware on the ESP32 doesn’t change the limitations of the Nextion display.
