How to set a variable to the lowest value of a set of device values

I’ve tried to build a simple rule that uses a cascading set of If Then Else statements comparing the values of each battery level to $LowBattLevel and changing $LowBattLevel to that devices level if it’s lower. However, you quickly run out of the ability to nest IF THEN ELSE because the screen formatting

I believe you should be able to accomplish the concept with sequential IF / THEN statements rather than nested.

IF Sensor1 battery < $LowBatteryLevel
THEN Set $LowBatteryLevel = Sensor1 battery
ELSE //do nothing

IF Sensor2 battery < $LowBatteryLevel
THEN Set $LowBatteryLevel = Sensor2 battery
ELSE //do nothing

IF Sensor3 battery < $LowBatteryLevel
THEN Set $LowBatteryLevel = Sensor3 battery
ELSE //do nothing

Since each comparison ultimately sets the variable, then the subsequent comparisons will be against the lowest value so far in the series.

PS. There’s a Math with Variables feature request that you may be interested in casting a vote on.
