Seven Segment Display Reloaded - Send string over MQTT

[andywarburton]

Is your feature request related to a problem? Please describe.

I'm building a seven segment display, and as a standalone clock, it works great! However, I would like to use it in more of a smart capacity, connected to home assistant and use it to display things other than the current time (for example, a countdown, temperature, humidity, time remaining on washer etc).

Describe the solution you'd like
To do that, I need to be able to somehow send a string to the clock over the local network. MQTT would probably work just fine, and it seems that the MQTT functionality is already there. What I propose is the ability to send a string over MQTT and if it is in the right format, the clock will display it (there are also a few letters that can be displayed on a 7-seg). If a blank string is recieved, then return to showing the time.

Describe alternatives you've considered
Obviously, I could recreate the whole thing in ESPHome, or code it manually but that would lose me the all the fancy effects, audio reactivity etc that WLED provides. So the dream is to keep this in WLED

If you want to see the progress on my seven-segment pcb project and work in progress clock, check out my Mastodon feed. I will soon be opensourcing this whole project! https://mastodon.social/@andy_warb

Big thank you to the developers of WLED, and especially this project!

You will need to contact original usermod creator or last maintainer as usermods are generally not maintained by WLED team.

That would be @derqurps right? It doesn't look like he has comitted any code since 2021.

I will see if I can figure it out for myself... its been a while since I touched C but I'm sure I can knock something together

There is currently a PR with bigger changes here #4585. I would suggest forking off of this PR, as it will hopefully be merged soon.

I made a 7 segment display last year and ran it off of WLED, and sent all the commands for time, and other stuff like timers through home assistant as rest commands, which included segment data for each segment in the one command. If you want I could send you the commands and everything and see if that works for you?
