Cant find any useful info on what is the smallest browser that works with the node-red dashboard. That will be the only task. The normal browser i use for the internet is firefox butt that is much to bulky and memory hungry for only displaying the dashboard.
I suppose it depends if you are running the browser on Linux or Windows.
I have a few "lightweight" browsers as portable apps on my Windows 10 PC.
Without any effort to set them up I found:
K-meleon wouldn't display anything for http://192.168.1.11:1880/ui
Opera, Sea Monkey, Pale Moon and SRWare Iron worked. Iron consumed least memory.
Comparison between Firefox Portable (64 bit) and Iron Portable (32 bit):
Think more in a line of MQTT to BASH or PYTHON to display the data. Browsers are to bloat as is and i have not the skill to build one:( And off BASH i know a thing or two.
The LAN has NO internet connection even.
FYI, I like surf: https://surf.suckless.org/
You get a window with just the content. No tabs, no menus, no menubar, no nothin'
It is a web browser, it does use WebKit2, so it does bloat as the web page bloats...
