Hey everyone!
I’m currently trying to add the capability to respond to external data sources (sound, manually triggered events, smart flow toys) to a fleet of Pixelblaze powered LED strips in an installation. I’m starting with sound reactivity.
The installation is all wireless, so I’ve been trying to avoid needing to get a sensor expansion board for each Pixelblaze. My solution so far is to attach a sensor expansion board to either the Raspberry Pi I already have running Firestorm or to an Arduino and then have it send its readings through the network to a little Node server I have running which forwards the data to each Pixelblaze through Firestorm with setVars commands. I believe through some experiments that setVars only affects memory, but I want to double check that this approach isn’t going to fry the flash on each Pixelblaze.
So my question stated succinctly is, does setVars write to disk?
