Looks like it's a copy of a WH1081 Fine Offset unit.

You may find getting parts difficult as it is a discontinued unit.

Maybe time to upgrade as other sensors might start failing soon.

I hope to move in the next 2 years so I will just let it fail. Lets hope I can get it rotating again.

I stumbled on this thread 2 days ago and had zero clue on what a weather station was let alone why need one.

I purchased a WeatherFlow Tempest last night! Love GeekZone!!! 😂

You'll love it! Honestly one of the best purchases I made myself.

The amusing one is my father who pointed out the pressure change due to the volcano to me (even before GZ), and has turned into an absolute weather geek.

The Tempest arrived on 24th and I was able to set it up in under 10 mins. It's connected to my Hubitat & Alexa.

There's quite a few of us using WeatherFlow!

Has anyone got a problem with Spiders making a home in their Tempests and if so how you are dealing with it?

Yeah get the occasional cobweb in there. I’m just using a very soft extendable duster to delicately clean them out.

I give mine a light spray with ripcord every now and again, that seems to do the trick..

I've e-mailed a fault through to Weatherflow, I don't think the "Feels like" temp is working correctly, the temp it shows always matches the actual temp instead of taking into account humidity.

e.g my station homepage says its currently 21 degrees with 88% humidity, the feels like temp is also 21 degrees. The station near me which feeds into MetService is saying 23 degrees, 88% humidity and feels like 27 degrees.

I’m sorry that his thread is looking like a Tempest one, and I have just installed one, but I have a question about rainfall accuracy. I got the Tempest partly based on rave comments here but also because I was getting tired of the cheaper tipping ones jamming. Over the weekend we had around 50mm of rain in the Wellington area and I was looking forward to more data. Surprised to see only 22mm recorded on Tempest, 40mm on tipping one and 43mm in a glass tube reference gauge.

I know that you can upload other data and Weatherflow will then push out calibration corrections, which I will do, but how bad should it be out of the box? I understand over reading can be vibration or even bird feet. Looking at the other stations in the wider area I see massive variations. Has anyone else out there focused on rainfall accuracy and been through calibration phases.

For starters, rain is very variable so even side by side devices will measure different amounts as you've found yourself.

Secondly, it sounds like the Weatherflow uses a piezo electric sensor for rain detection. These are not suitable for high accuracy applications and indeed organisations like NIWA don't use them for important sites: https://niwa.co.nz/our-services/instruments/instrumentsystems/products/climate-stations/ota-type-tipping-bucket-rain-gauge

BTW 'Climate stations' use the highest grade weather station equipment.

Calibration is a can of worms because you may apply a correction factor which you have determined at one rain rate only for it to skew your results even more at higher or lower rain rates.

Basically you'll have to accept it is a rain indicator not a rain gauge.

Main advantage of the piezo electric of course is no moving parts so it's suitable for a low maintenance application such as your average home user.

Most of the posters in this thread are just like chimpanzees on MDMA, full of feelings of bonhomie, joy, and optimism. Fred99 8/4/21

Get a response from them?

I noticed mine and several others around me all have the same actual and feels like temp

Can someone please explain briefly (don't spend too much time) why you might want to have one of these?

You can look outside and see it's raining, sunny, windy, snowing etc, and weather reports make some attempt of predicting future conditions. I just don't see why you'd want to spend money so that you can pull out your phone for it to say it's hot when you can already tell.

Thank you for feedback and I agree that with this detection method it is only an indicator which is ok for my use but I was hoping it would be a better. There shouldn’t be too much local effect in this case as they are all clear of structures. I feel this potential poor accuracy needs to be well understood when choosing a system.

Main reasons are having a history for reference (don’t tend to note down the daily conditions) and probably the most useful is if away from the property, especially in other parts of the country, to have some guide as to what weather has been delivered. I have given up on the cheap units that can jam for rain as completely wrong data worse than none at all. Like many of our tech purchases, probably not needed but satisfies some want 😀
