Wrong values in Factory Sensor

Votes:

0

Hi It seems that the Factory Sensor is a bit buggy. From time to time it takes the wrong values from the original sensor. I have a factory Sensor Like that:

  1. 2:chan Channel(3898,1)

This Factory Sensor is paused from 1 to 9 am. Sometimes afer 9 am, if the sensor start to operate, the values of this channel are different then from the original channel of sensor 3898. Example:

Sensor 3898 , Channel 1 has the value 178 but factory sensor shows me 203 ... I can try to put the recheck button but it doesent help.

A workaround if its happen is just to ad a 3rd channel like:

  1. 3:chan Channel(3898,1)

Afterwards the right value is in the factory sensor. Afterwards i can remove the sensor without a problem and everything seems to work right again.

Is that a bug or a wrong configuration?

Potential bug. We're looking into this and, if necessary, will provide a fix as soon as possible. Please bear with us.

We double checked on this. The issue has to do with factory sensors not interpolating, so that the live data being used by factory sensors are the values of the previous scan. So, it is possible that certain discrepancies ensue if one of the entries is "lagging." Seeing as it would demand extreme resource load to use synchronized pull / push requests, I'm afraid this will remain so, as otherwise this could have a detrimental effect on performance. Sorry.
