    • Easy with many added improved features.
Have used weather stations for years and years. I have spent so much money on weather stations only to get half of what I got with this. First off setting up this weather station is the fastest and easiest by a very long way. It is just almost fool proof and really anyone can set it up and get great results. Next off accuracy well I have it against a Davis and it is looking around the same most of the time it isn’t quite fair as they are not in the same place and it is getting sometimes a little more wind-chill. Rain accuracy, there are a lot of complaints that it isn’t accurate but I have to say so far it seems to be about spot on and I do LOVE that it alerts you when it starts raining. OK here is the one I am still totally amazed about. I live up almost a mountain and the weather actually can be very different here than three miles away. It can be snowing here and nowhere else near There have been days where it has been raining three miles away all day but no rain here dry as anything. So weather prediction one day during this winter was no snow for another week however tempest told me we we’re about to get snow I called bull. It snowed here dropped about four inches and literally down the road about two miles away nothing!! I have finally experienced it’s lightning feature wow what a nice added bonus to having this weather station. I am a bit of a silly fiddler added this tempest to HomeSeer so when it detects lightning it then plays a thunder sound across the Sonos speakers. Of course I forgot I did that and the other day I could have sworn I saw a flash but. Anyway within the next few seconds I heard Sonos playing a loud thunder sound that made me jump out of my skin. I might have to disable that. So overall I think this product is really fantastic I just hope it lasts a long time. Most of my other weather stations when it got time to change the battery never worked well after so this has another added bonus of never having to change the battery. Did they think of everything!!!? Maybe. There are a few negative reviews for this and most of them mention the reason is rain and wind direction. I personally think that if you need to reply on rain reporting then you need a separate rain sensor however this so far has been fairly accurate in comparison to my dying Davis. The wind speed and direction show the same as the Davis so I don’t see any issues there. For the people who had the device fail after a year that isn’t so great and maybe the company should send a new one out after all this really should last at least five years in my opinion. Time will tell. ... show more

    • Best? all in one PWS for home or remote operation.
Pros: - Easy to setup. Easy account creation, simple to connect to 2.4G WiFi, hub unit finds and connects to Tempest easily. The distance between my hub and the Tempest is a good 75ft and it has been totally reliable. ***See edit at bottom. - Easy to mount. Will work with standard 1-1/4" OD TV antenna mast pipe. Point magnetic North with a compass app, tighten clamp and walk away. - The Tempest app really seems polished and presents the info in a logical fashion. And since it also has week+ condensed forecast, it's become my go-to daily driver weather app as well. Lots of options for setting units for pressure, temp, wind. Wind from-direction can be Sub-Cardinal (NNW etc) or Degrees (1 deg resolution) which is awesome. - Update Refresh Rate. Stated to be under 3 seconds, very close to 2 seconds IME. Seeing the wind direction and wind gusts update in real time is amazing. - Accuracy. At first when comparing to other stations I thought it might be off a bit, but I've begun to realize that "hyper-local" conditions really can be quite different than a station a mile away. Sometimes humidity or temp is lower, sometimes higher. That's ok, because it really is, and that's the beauty of a PWS. So overall I seen to be getting very accurate readings. - Durability. WeatherFlow says it's made from a Marine-grade plastic, and it really has a solid, professional feel to it. Best part is there's no anemometer or vane to get snapped off from a twig hitting it. And no maintenance for a clogged rain gauge like on other stations. - Start of rain event notification. For home or a remote location this can be very helpful to know when rain is starting. ( Will catch that storm front light rain before the main rain arrives) - No batteries to replace. Solar cells recharge the battery. Extreme northern locations may struggle a bit but I think they have a booster battery option. - No monthly subscription needed. - API for reading values via local network OFF GRID. Amazing. - The Tempest web site shows all the other stations and there are a lot of them. You can also hide your station. - Alexa integration. Scary easy. "Ask WeatherFlow what the humidity is" etc. From FireTV and other. Cons: - Like any all-in-one PWS, there is a compromise for various readings. If you want accurate wind they say get it up 30 ft in the air, but then perhaps the near-ground temp or humidity might not be as accurate ? I favored the higher mounting myself for less obstructed wind readings. A lot of it depends on the surroundings at your location of course. - The rain sensor seems to use a literal microphone to measure rain hitting the top. It's just not very accurate. And if it is really windy it will show heavy rain when there is none. The rain sensor is a fail if you need truly accurate measurement IMO, but for general things like rain start and generalized rain rate and accumulation it's ok. - See edit/update at bottom of this review for a connectivity issue. Hoping it will last a long long time, as it does cost a bit more than some. Still, it's a bargain IMO compared to Davis Vantage Vue and some others. ***Edit/Update: Had a big wind storm and the power got knocked out for 6 hours or so. After the power was restored, the Tempest sensor unit would not connect to the hub. I had to wait till next day when winds died down and take the big mast down, remove unit, and re-pair to the hub. Also, data was supposed to be saved in the Tempest sensor unit for some period of time, but nothing backfilled historically. So, I would have concerns about deploying this remotely where there is no access at all to the sensor unit. ... show more

    • Made to Last
This is one of my most favorite products. For the last 20 years I have had those traditional weather sensors, but they never seemed to last because of deterioration from the sun's UV rays and constant movement of the wind vane that would wear out and break after a couple years. And then there was the rain cup that got clogged from birds pooping in it or trying to build a nest. This product does not have any of those problems. It is very cleverly designed. I was a bit doubtful at first that it might not sense rain properly or the wind speed, yet when I look at results from the local airport or other sensors around the area, my unit matches well if not better. At one point I put a cup out in the yard to catch water from the rain and compare to the weather station and it was completely accurate. So, the big advantage of this system is no moving parts to year out. Unlike other systems, there is no indoor display that might be nice to have as an option, but the iPhone app and the ability to look at results on the internet is fine for us. I like the app, however the easiest thing for me to do is to ask Alexa "Ask weather flow what is the weather" and it will announce the values from the system in our back yard. If there were an optional indoor display, I might buy that as well, yet the app and Alexa announcements are good enough. I also like the lightning detection feature to see when and how close it thinks lightning is near the house. Bottom line is reliability and accuracy. It is a little expensive but so are other higher end systems that just aren't going to last as long. It also looks unobtrusive due to the simple design. There is also a nice online forum with many active members to give help or advice. As an engineer, I am impressed with the overall design. ... show more
