@revk@toot.me.uk @penguin42@mastodon.org.uk @dragonarchitect@rubber.social Can you push images via MQTT or does it take some kind of textual/JSON description then render the image locally or what? I do have a local MQTT already for aggregating sensor data so it would be straightforward to push whatever format to it

@revk@toot.me.uk @penguin42@mastodon.org.uk @dragonarchitect@rubber.social What I'm looking for at this point is a turnkey solution I don't have to spend a lot of time on. I don't have the budget to pay someone to develop custom firmware/hardware just for this project, but if it's available as a COTS solution I'll buy it.

@azonenberg@ioc.exchange @penguin42@mastodon.org.uk @dragonarchitect@rubber.social My code for now has various ways to decide what to display, and mix of text and images and so on and based on sensors, and MQTT data. But a simple "push image" is possible, png, at present designed for B+W and for full colour LCD, so I would have to play around to handle B+W+R. MQTT would say what URL to load for the PNG.
