Hi!
Is this text understandable and can it be used as a template for a recipe?
Additional spread calculation (dew point) for outdoor and indoor sensorsEcowitt consoles only calculate the dew point for the outdoor temperature/humidity; the dew point is not calculated for any internal T/H sensors.
If you also want to set up dew point monitoring indoors - for example due to possible mould development - you can do this with FOSHKplugin.
For comparative analyses, however, the temperature valid at the respective time is required in addition to the dew point, which is a hindrance for subsequent analyses.
For this reason, FOSHKplugin calculates the so-called
spread - the difference between the air temperature and the dew point temperature - instead of the dew point. The greater the spread, the lower the relative humidity and the lower the spread, the more humid the air.
If the spread is 0, the air temperature and dew point temperature are identical - the air is saturated and therefore cannot absorb any more moisture - the moisture is deposited on surfaces.
The spread value is therefore already the result of the comparison of temperature and dew point.
With the configuration option (this optional calculation is deactivated by default)
Export\ADD_SPREAD = True
in foshkplugin.conf, the additional calculation of the spread can be activated for the outdoor sensor as well as for all WH31 and WH45/46.
FOSHKplugin uses the following keys for the respective dew point difference:
outdoor: spread
indoor: spreadin
WH31: spreadN (where N = 1..8)
WH45: spread_co2
These keys are part of the (daily) CSV and are transmitted via UDP and in banner, tag file (
example), MQTT and InfluxDB forwards when ADD_SPREAD is activated. The values can also be retrieved via http and used as triggers for user-defined push notifications via pushover.
For all other forward types, these keys are in a blacklist and are NOT transmitted automatically.
If you want to switch off this blacklist for a specific forward in Ecowitt format, you can do this by setting the line
FWD_OPTION = blacklist=False
within this forward section in the configuration file foshkplugin.conf. A separate block could be used to display these values in the PWS dashboard, for example.
This function is available with
FOSHKplugin v0.10 from beta 240308.
Is this function interesting for you?
