[JonathanLee]

• fixed lock file issues
• use of -vss versus -vvss speeds up code 38%
• set lock file to ram for less ssd use
• added a email alert for an offline device

use of this # --- Ping Pico ---
if ! ping -c 3 -W 3000 "$PI_IP" >/dev/null 2>&1; then
PICO_ONLINE=0
else
PICO_ONLINE=1
fi

seems to respond better as it will try 3 pings each one will wait 3 seconds for a reply if one gets a reply it sees it online if not you get your offline condition.
