What I’m trying to do is, store an “unavailable” or “unknown” state from any of a list of devices while I’m away, and then be able to call those times, devices, and states later on (probably through a TTS service when i ask. But that part i know, its just the storing, and recalling i need help with).
I dont mind figuring it out, once i know where to start.
Or set your node-red context variables to be stored on disk - then they will be written out each time your save them and you can read them back in at startup time
