Calibration values

Sorry if this has been asked before. Couldn't find it..

Since the plugwise order is still underway and I am already setting up I have a question about the calibration values.

Do the values change or are they steady as per Circle. I ask this because I saw in the .py code that the calibration value is polled every time a power request is done whereas I would expect to poll the cal values only once and keep them global for next Power info polls.

Thnx

I remember reading about that.
I believe the values are steady, but it was in the script the way it is because of 'lazyness'

I'm not sure also, need to test this still.
But you need to make the function anyway so you can check if the values chnage over a period and adjust accordingly the call of the function.

OK, I will see it for myself once I got the order (which is not going to happen before X-Mas anymore I guess :| )
In my current setup I get the values once and store them into a HouseBot property and get them from HouseBot each time I do a Power calc. I don't have a clue how fast all of the serial traffic is going to be so I created a continuous loop which addresses one Circle each six seconds. Circle 1 will be addressed again 9 times (9 Circles) 6 seconds after the first poll. I don't want to send Decice Info requests if they are not necessary.

Now working on the .py pow() function. Don't know what it is yet and I need a similar thing in vbscript. Will figure it out though however it is kind of hard without the actual hardware..

OK pow() is to the power or ^. Easy :oops:

Now the number 468.9385193 is up. I think I will dry test this on know values from this forum.

The calibration settings are steady. They don't change after you get them out the factory.
Please note that pol was merely a prove of concept code, and that's not a realistic script/use scenario for your own software.

Funny how I was just reading that in an earlier post by you.
