I get crazy peak readings from all my sensors now and then. (Extrem high or extrem low.)
Is there anything I can do avoiding this?
This becomes a problem when logging the values and plotting them in a graph, because of the scaling of the y-axes.
Peak value readings from sensors
Re: Peak value readings from sensors
There seem to be some outliers, but based on my experience with Fibaro temp sensor I wouldn't call your readings "extreme"
This second graph of you has a somewhat wider spike in the middle. Is that the result of one single datapoint which is streched by the graphing technique, or were there several outlying datapoints?

Re: Peak value readings from sensors
The examples was not the most extreme. I have to reset the log all the time to get readable graphs.
I have attached two graphs today that show extreme spikes.
This one showes live power reading. Like you can see the spike makes a problem. This one shows reading from one of the same temperature sensors that I attached in my last post.
The stretched peak you mentioned is one singel point. The graph is stretched because of few readings in that period.

Re: Peak value readings from sensors
Then it looks as if it is the same problem I experience (I no solution and no clue what have caused it)
What brand/type of device do you use? Mine are two Fibaro Universal Sensors (which are pretty useless for detecting a fire alarm)

Re: Peak value readings from sensors
I have Aeotec multisensors and aeotec home energy meter.
But could I be sure that it is the sensors and not the razberry mixing up or registering false readings?
My latest installed sensor which is located outside, doesn`t seem to be affected, and I can't remember the energy meter making bad readings before upgradeing to v2.2.1.
I have now excluded and included one of the sensors on a new ID, to see if that could help.
Of course it can be external elements affecting the readings or the transfer of the reading failing, but I suppose there is some kind of checksum verifying the values transfered in the z-wave protocol?
