I have 2 pressure tanks for tennis balls... I'm trying to make a webcore piston that will check the pressure of each against the desired pressure
When I go and do the if condition and specify $device, I don't get the attribute pressure as an option
the TB Tank devices have an attribute for pressure
I have a difference webcore piston that I'm using and it had several door sensors and I could use the temperature from each of those...
Not sure what I'm doing wrong...
Temporarily add the real device in the statement so the attribute will show up, then you can remove it after your statement is complete.
you can also try to use staging.webcore.co, that may have a fix for this also
I tried both suggestions but unfortunately did not help.
I guess I'll have to make a piston and then duplicate it and update info.
Sorry more questions...
I'm trying to calculate the remaining time by subtracting an endtime from now
the endtime is an attribute on my TBTank device
Q1. There is no way to do the math {now} - TBTank EndDateTime ...right?
I think I have to set a DateTime variable equal to the device attribute...the thing is that its not available
I tried on staging.webcore.co/ also but same result... sorry its been a while since I did webcore but I don't think I forgot everything : )
You may be able to use and expression
datetime(device:attribute)
The attribute is likely a string, and datetime should convert it to a datetime type.
Full logging may help
Q1. I think I tried what you said....am I doing something wrong?
Q2. I switched to read the attribute into a string dt and then try your datetime function converting the string to a datetime variable...but that doesn't seem to work
Interesting, that device does not present standard ISO 9660 times...
You may need to parse the string into pieces
ie you want to do a date('2023-05-30') and then a time('21:43:40'), then add the datetime=date+time
I'm not near a computer with monitors to play with this.
The most common format is:
"yyyy-MM-dd'T'HH:mm:ssXX"
"yyyy-MM-dd'T'HH:mm:ss.sssXX"
Usually there is a -0400 or some such at the end for the time offset from GMT
that function worked perfectly...thanks for the assist!!
so my application is to pressurize tennis balls for a specific pressure and for x days
On the driver page I input desired pressure and number of days
I want to create a tile that shows
Desired pressure: xx
Actual pressure xx
Remaining Time 4 days 8 hours
What is the best way to do that?
Does webcore somehow update an attribute or global variable and have something like Simple MultiTile display or is there a good way all within webcore to update a tile?
Thanks for any suggestions
