Not sure why you want to use the 3 axis references. Her is a link to the Rule I use and it works great.
I am also using a Samsung V5 Multipurpose Sensor. I stuck it to the side of my dryer with Velcro tape.
LaundryRunning: Boolean -> False
Legit: Number = 0
Trigger: Vibration Sensor Active
IF (Variable LaundryRunning(false) = true(F) [FALSE]) THEN
Set LaundryRunning to true
Repeat every 0:03:00 (stopable)
IF (Dryer Sensor inactive(T) [TRUE]) THEN
Stop Repeating Actions
Add 1 to Legit
IF (Variable Legit(0) > 3(F) [FALSE]) THEN
Notify SM-G970U: 'Dryer Cycle Complete @%time% on %date%'
Set LaundryRunning to false
Set Legit to 0
Basically it runs for 3 mins, checks to see if its off, if not it runs for another 3 mins, etc.
The Legit value> 3 means it has to check 4 times or 12 min. before sending a notification.
This helps from getting false notifications when you are checking on it or folding clothes.
If you change the legit to >2, that means running for 9 min.
My notification is different, I use Inovelli LED bars for notification. They flash yellow for 15 minutes.
