On my other R-Pi devices I regularly run software updates using apt-get update followed by upgradenas they include security updates etc.
I’ve been running PiAware for a good few months and never done an update.
My Stats page shows PiAware (Debian Package Add-on) 3.5.0 - iso looks like I need an update at some point but I’ve seen reference to “Send command to device” feature. I cannot find this anywhere on my setup. Was this only available in the earlier version?
