"TimerRepeat": {
"quake Mild": 2700,
"quake Medium":5400,
"quake Intense":10800
}
}

I noticed it ran one but then tries to run the rest at the same time. Any ideas?

hello, its just simple i try to explain how. its a repeat timer, after 2700 sec it runs the first command "quake Mild" so now this timer resets and start again to count but if its start again your sec timer and command "quake Medium" is trigger at 5400 and at the same time your first trigger.
2700 + 2700 = 5400

time line example
0-----2700-----2700-----2700-----2700------2700-----2700-----2700-------2700
0----------------5400-----------------5400----------------------5400-----------------5400
0-----------------------------------------10800--------------------------------------------10800

i hope its understand :D

Got it! Thanks!
