Tempest: comparison of values

Comparison of values is required to see whether the sensors are within margin relative to the specified characteristics.
Not only relative to other sensors in the configuration, but also related to available references.

Addition of Tempest_PWS is an aspect resulting from the age of my WS7000-PWS, in combination with the limitations of TFA_Nexus_PWS.
A 'problem-solving' solution is addition of a complete, modern PWS to the present configuration:
after validation roles intended to be shifted, with Tempest becoming primary PWS and TFA_Nexus and WS7000 as complementary/assisting PWSes (or disappearing).

The info for display of the Tempest_PWS now temporarily via 3 external sources and 1 local source:
- the Weatherflow-stationwebsite,
- from that a related WU-link, followed by Meteotemplate
- parallel a linked variant of the PWS-Dashboard,
- the local WeeWX-software generates from the locally received UDP-messages a WeeWX-Dashboard.
The user has no influence on the Tempest-display for the first 3 weblinks.
The data feeding the WeeWX-weblink can be locally adjusted, as required for calibration.

Linking to&from the 'System' is next step of integration.

First phase of that integration is reading from Weatherflow via JSON-call and by data-reading by Domoticz from the WU-link.
After extraction of data an export/upload to AWEKAS_Stationsweb
incl. the required calibration-corrections.

The next Experimental comparisons are aimed at mutual alignment of sensor-data.
Periodic comparison at a timeline for significant sensors of the TFA_Nexus_PWS and WS7000_PWS and of selected light-sensors.
For the new posibility to view lightning strikes, a timeline-comparison has been added relative to Tempest's meteo-sensors.
Mind the aspect of RRDTool that scaling is automatic and that rain/24hour for < 1mm is shown on a scale of 0m ~ 999m.

All Temperature-, Humidity- and Wind-sensors as "out of the box", with some minor, mutual bias-alignment.
Rain gauges of Nexus en WS7000 locally checked for flow.
Air pressure elaboratedly checked against KNMI AWS_Twente, resulting in alignment for Nexus and WS7000.
Data via GW1000 from WH31A_T&H and WH40_Rain, and it's AirPressure not yet aligned, and therefore 'experimental'.
Light&UV compared with online calculation models, and plausibly aligned.

Experimental graphs incl. GW1000-data:
Temperature
Rel.Humidity
Precipitation
AirPressure

In the (dutch-language) sections describing experiments with light-sensors and wind-sensors an elaborate discussion on the required corrections and alignments.
