I have node-red running on an RPi in my local network. None of my devices are accessible from the outside (no port forwarding at all)
I have a Telegram bot that i use to instruct my node-red to pull data from other devices in my lan and reply via telegram. This is working fine for texts (like status of door locks) and images (home security cameras).
Now I'd like to use a similar setup to have node-red to forward me an internal webpage from a device in my lan.
I tried two webshot nodes, hoping they could capture the page and send me the image via telegram as an image, but none worked.
I could pull the html into node-red, but I can't serve it (the RPi is not forwarded) and I don't think i can pass a complete webpage via Telegram.
I also looked if there are screenshot standalone scripts that run on a RPi, that I could trigger from node-red (so i could grab the image it would generate and forward via telegram) but didn't find any.
Would anybody have a suggestion how to tackle this project?
