I have a Popp Z-Rain device and several questions:
The measurements are updated every approx. 4 minutes if there is a change. This is as described in the manual.
I would like to get an immediate notification/update when it starts to rain (open windows…) and not have to wait up to 4 minutes. This seems to be possible via association groups, but I don’t know how to use them. Should I add the main controller to the association group 2? How can I get an item updated from there so I can use the immediate update in a rule?
What are the 3 measurements sensor_general, sensor_rainrate, meter_water_cubic_meters meaning exactly?
What unit (mm, mm/m^3,…)?
sensor_general seems to upcount by 0.5 per seesaw dip and not resetting to 0.
sensor_rainrate is upcounting by 7 per seesaw dip and resetting to 0 if there is no further dip after 4 minutes.
meter_water_cubic_meters is upcounting and not resetting to 0. It is the same value as sensor_general, but with a scale of 1000 (when using default config meter multiplier of 1). So f.e. sensor_general shows 167.5, meter_water_cubic_meters shows 0.1675.
How are the measurements related to the configuration parameter “Rain counter” that is at 1305 fix (default config) here? Shouldn’t the Rain counter count up?
- Is there an items/sitemap example that someone would like to share?
