Great app. Works really good.
Two questions and/or requests:
1/ can’t seem to connect to a virtual device. Would love to have separate (sub)devices for eg rain and wind. Anyone got this working?
2/ I get false readings on rain starting both via Logic rain>0 and the action card ‘rain started’. The Tempest it self doesn’t show rain. Believe it’s only when it’s quite windy. So perhaps the Tempest own algorithm rules it out. But the API pushes values thru? Anyone else with this problem?
I didn’t see this problem but I’ll check if I have the same. I do know that the Tempest waits much longer to give you a ‘it’s raining’ notification and I think only above 0.01mm. The Homey app shows you even a drizzle, if registered by the Tempest. I think that’s a good thing but it’s true that wind might trigger a fake rain event.
I tried to make rain>0.05 and ended up rain>0.2, but it still activates even though it’s not raining. But again, quite windy. And my Tempest is mounted on a top railing and is exposed to some movement.
Any idea on the virtual device issue?
@Will_o_Wisp It’s really a nice app. Thx.
I replaced my Netatmo rain and wind gauge with the WeatherFlow tempest. A world of difference.
I have set-up a dashboard and need to show e.g. temperature, rain and wind strength on different tiles using a virtual device. But the data from the Tempest doesn’t show in the virtual devices. I can ofcourse show the Tempest in the dashboard, but only showing one sensor reading (wind or temperatur or rain etc.).
I also use the app temperature manager to group different temperature devices and show an average. This also doesn’t work with the Tempest. It doesn’t show as a temperature device and can’t be included.
Perhaps the solution to both of the above mentioned use cases are linked?
Is this something you would consider looking at?
I have not experienced any false rain start with my Sky device. I now have a Tempest device since a few days and will see how it behaves. What wind strength are we talking about when you experience false rain reporting? Does it even show some mm of rain in the Homey App UI for the tempest device at that time?
I have only experienced with very strong wind, e.g. >17-20 km/h. And my Tempest is mounted on a railing, so perhaps it starts vibrating?
Ps! Thx for following up
I understand. Do you have any idea/suggestion how to get around getting false notifications in Homey due to heavy wind? I could make a rule combining rain and wind, but would miss those occasions when it’s actually starting to rain when it’s also windy?!
I see that there are IF cards for Wind with the option to enter a value. Is it possible to make the same cards for temperature, brightness, UV? This would make my flow’s for sunscreen so much easier.
What are your experiences with the Tempest weather station?
Is it suitable to control an awning with it. So as soon as the first raindrops fall or wind gets stronger or gusts of wind arise?
With the Netatmo weather station, this is not possible due to the interval of 5 minutes, for example.
For me; yes. But I don’t rely on the rain indication of the app. I created a variable that sets the rain measurement on three decimals. This works much faster than the rain indication, which (I think) only starts with 1mm of rain (for a few minutes).
I have some flows to open and close my sunblind. Like @martijn_C did I did as well, create a variable for the rain.
The only thing i’m still struggling with is the wind, i have a feeling that the wind measurements are incorrect. But that’s a feeling.
Rain
As soon as the first raindrops are detected, it will be reported. After all, this is necessary so that the awning closes immediately.
There is also a card in the app for this: It starts raining.
Therefore, I do not understand the need of a variable. Maybe one of you could post the flow so I understand it better maybe.
Wind
In the FAQs the following is is explained about the wind measurement:
Every 3 seconds the ultrasonic transducers sample the wind speed and direction. These values are averaged in one-minute observations. The lull is the lowest of the 3-sec readings and the gust is the highest of the 3 sec readings. The one minute averages become part of your station’s long term record. These are World Meteorological Organization (WMO) standard sampling methods.
What does it mean exactly? At what interval the values are reported to Homey? Every 3 seconds, or only every minute?
They can write that but it doesn’t work like that. The ‘it starts raining’ indication takes way longer than that and only starts after more than a few drops. So, that’s why we create a variable. The variable registers rain much earlier than that indicator.
