Bitmasking with a global variable

[NC-Lou]

Hi,

Does anyone know of a way to do Bitmasking with a Global Variable in an Event. I am trying to simplfy how I do home presence updates, and I want to do something like:

Every Two Minutes

If Person_A is Home

Home Indicator = HomeIndicator LOGICAL_OR Person_A_Home_Mask (00100)

If Person_A is Away

Home Indicator = HomeIndicator LOGICAL_AND Person_A_Away_Mask (11011)

etc...

Then I could check every few minutes to see if the HomeIndicator is Clear

Thanks,
Lou

Quick follow-up

I couldn't figure out how to do it in a Homeseer event, so I did it in Homeseer VBScript and it was super easy, and simplified my events quite a bit.

In summary, I created a script which triggers every two minutes, and does the bit-masking on a device. Here is a snip-it of the code:

Dim Occupany_Mask_Clear As Integer = &h0000 '0000-0000-0000-0000
Dim Occupany_Mask_Set_Lou As Integer = &h0080 '0000-0000-1000-0000
Dim Occupany_Mask_Clear_Lou As Integer = &hFF7F '1111-1111-0111-1111

Dim DVRef_Home_Occupancy As Integer = 9999 'This is the Virtual Device that will trigger Alarm setting
Dim Life360_Home_Lou As Integer = 8888

Dim Interim_Indicator As Integer = Occupany_Mask_Clear

If hs.DeviceValue(Life360_Home_Lou) = 1 Then

Interim_Indicator = Interim_Indicator OR Occupany_Mask_Set_Lou

End If

hs.SetDeviceValueByRef(DVRef_Home_Occupancy, Interim_Indicator, True)

Then I have another event that check the device value periodically and engages the Alarm based upon Occupancy and Time of Day.

[pseudocode]

You can do it in an event with an immediate command - I have a bitmasked status on one of my controls (device 1706) to show multiple things going on in parallel.

Set: &hs.SetDeviceValueByRef(1706, hs.DeviceValue(1706) Or 1, true)
Unset: &hs.SetDeviceValueByRef(1706, hs.DeviceValue(1706) And 254, true)



To add more context, I have a device (from my ControlsPlus plugin, but that's not the point) with two buttons that trigger events to vent rooms. Each room has two events:

* Event on button press - open window(s), start timer, set bit in device
* Event on timer 15 mins - close window(s), stop timer, clear bit in device,

This works nicely because if you click the button again it extends the vent time for another 15 minutes, and the device shows the status based on the bitmap.


When I get another room with Velux windows I'll extend this to have bit 4 as well.

Thank you, I didn't know about the immediate commands, that will work nicely.

Thanks!
