I have a
GW1100A weather station that connects to Home Assistant via
Ecowitt integration. Currently, it provides me with these measurements

Yesterday we had a storm and lots of rain. Right before,
solar lux changed significantly.
(no screenshot for
relative pressure as it seems to be almost, if not exactly, the same as
Other values changed as well (less
UV index, more on all
rain entities, higher
wind speed, etc.).
Do any of you that use weather station have some kind of “reliable prediction” routine to determine whether or not there might be rain / thunderstorm / “bad weather” coming very soon? I mean, yeah, there are
weather entities that already tell me that it might rain today. But these are for the general area. This morning, my parents living ~7km / ~4.3 miles away had rain, nothing at my place. Now it has shifted to here, while they don’t have any rain at the moment. So this general area warning is too general to actually determine my exact locations weather conditions.
A use case might be to get a warning “if there is laundry drying outside, collect it NOW” because it might start raining very soon. Or (if the prediction can be made for a point in time not that close) “don’t take the dogs for a walk now; it might look sunny, but will rain in x minutes”. Just some ideas.
Currently, pressure is still up. Then again, the weather is still kinda bad. I vaguely remember something about being able to determine thunderstorms if x (pressure drops, then rises??? I cannot remember). While I could just research this, I am sure it is more complicated than that. So I cannot just use two
input_booleans (one if pressure drops by x percent, and one if after this it rises by y percent); especially now: pressure is still up, I believe it is a little bit higher than usually (but cannot say for sure as I haven’t had this weather station for long).
And yes, the device will tell me current rain status as well - but by the time rain has already starting falling, it is too late. By this point, I would know because I can hear or see the rain. The warning about getting the laundry inside would need to be sent before it actually has started to rain.
So I thought, perhaps somebody here actually knows these physical rules that one could utilize for an automation or script… if this is the case, would you be willing to share yours?
Thank you in advance for your input
