I built my own, based on https://github.com/rmd6502/esp_lights

I took an old phone and fully reset it to use for all these shitware apps. I’ve looked into buying an anonymous SIM card so it won’t be at all connected to me, but the underlying assumption seems to be if you want that you must be a drug dealer. Best I’ve found is mysudo, which requires payment, but it’s really not much, and only stores the minimum on their side. Gives you an anonymous email and phone number. The other problem with all these apps is the engineers are given at best half the time they need to do a good job, so they’re always buggy, insecure, and have a shitty UI. But some project manager managed to show Impact and get a bonus.
