What's your weirdest or most unique self-hosted use case and solution? (lemmy.today)

I'm self hosting on an old laptop, and I'm a convert for life. Self-hosting is amazing. Looking for other people's weirdest examples of what they're doing as inspiration.

My example, I recently set up a grammar script, where I have a couple 8b LLMs and an html landing page. I upload a doc and it corrects grammar and highlights changes it made, or just proofreads and I make changes manually. I can upload a novel before bed, and have suggestions based on specific writing styles in the morning. All local, perfectly suited for my own work.

I am selfhosting HomeAssistant and one automation is for my ceiling lamp. As I don’t whant to touch the electrical wiring or alter it permanently, I control it via IR and imitated the signal from the original remote via the ESP32 and some IR led. This on his own does not build a full feedback loop, so the ESP does not know if the light changed after the signal got send out. I lacked the correct light sensor in my inventory but remembered that my clock got one for display brightness control. The clock supports MQTT and also exposes the light sensor values in HomeAssistant. So after the ESP sends a signal to turn off or on the light, the automation looks at the light value from the clock to validate that it worked, else it tries sending it again.

Home assistant, is the light of on?

I don't know, let me ask the clock.
