SHM Posted February 23 Posted February 23 I have a motion sensor that detects the presence of my car in the garage. The presence or absence (1 or 0) is saves in a state variable, $caringarage. When there is a power failure or any event that causes the Polisy to re-initialize, $caringarage is reset to 0. The ISY manual shows a way to preserve the state variable value, but the syntax is confusing. Any suggestions/examples?
paulbates Posted February 23 Posted February 23 There is a way. Right after you set the variable, put an 'init to' as the next program statement with the same value. It will survive the reboot.
paulbates Posted February 23 Posted February 23 (edited) Here's an example I use to keep data for my sump pump. You' ll always need two variable statements, one to assign the value, and one to tell the isy to remember it even if it reboots. If 'TimeData' Day of Month is 1 days And Time is 11:59:55PM Then $Sump_Pump_Maximum_daily_Gallons = $Sump_Pump_Gallons_Daily $Sump_Pump_Maximum_daily_Gallons Init To $Sump_Pump_Maximum_daily_Gallons Edited February 23 by paulbates 1
