      Option #1: speed & direction

    2. Ed Ernsdorff on

      Speed and direction.

    3. Rees Maxwell on

      Count me in for speed and direction, and for making it really useful for direction via various mounting methods which take that into account.

      What rob rainman says

      wind direction is must, so option 1

    6. Miguel Mateo on

      Either option, or suggested option 2 to get direction are OK, BUT you can not attach it to a wall, that will alter both speed and direction of the wind. This is supposed to be mounted on a pole some how.

    7. Arnaud WOROBEL on

      Totally Agree with Rob Rainman.
      Wind cups are better because it capture a breath of air in any direction.
      Furthermore, it is necessary to separate power and wind direction because with option 1, when wind change direction, you will have a drop in power. It will give uncorrect data.
      Most anemometer have a dedicated wind vade for that reason.

      Bearings quality is really important too for durability and very low friction : Full ceramic bearings are great although they are expensive.

      So option 3 = option 2 + dedicated wind vade below + good quality bearings :)

      The wind cups design from option 2 with a separate wind vane for direction is the way to go. has to be a pole mount, the wall mount is a fail.

      Dox Doxiadis on

      I'll go for option 1 as well.

    10. BloomSky 2-time creator on

      We are working on it! You guys are amazing! These ideas, drawings, suggestions are AMAZING! Markable to those who mentioned about mounting options and vane position, we will definitely take into serious consideration, even at this early stage of the product development.
      Note for everyone, this is way far to be finalized. So no worries, we will redesign based on your great suggestions, then put into testing, testing, testing, until the one that works most durable and reliable. Normally this will takes up to 10 months, so we will keep you guys posted accordingly. Thanks all.

    11. Owen DeLong on

      Speed only is useless. Direction is the more important data. Even for a $40 difference (though I think you guys should be able to get it below $20, frankly), it's just too important a piece of data to leave off the direction.

      Knowing when the wind changes direction and which direction it's going is key to knowing what's going to happen next. Often in the bay area, the wind changes direction even before substantial barometric pressure changes become locally visible. If the wind is out of the southeast, you know the weather is either bad or about to get bad unless the flow is very very weak.

      I also agree with Robert that a direction-added version of option 2 is preferable to the current option 1 design.

      Further, the commenters that pointed out that putting a directional sensor on a wall is just plain dumb are also correct, please don't do that. Pol mount or roof-peak mount, please.

    12. Wesley Zielicke on

      Option 1, the other one does not have as much, unless there is a huge price difference

    13. SPIN remote B.V. on

      Definitely option #1.

    14. Robert Corkum on

      That didn't work at all. :) (spaces were removed) Here is a link instead:

    15. Joe Christy on

      Option 1 please, w/ poll mount

    16. Robert Corkum on

      I would like both wind speed and direction especially at this level of investment.
      However, I'd have to go with combination of both designs.
      Option #2 wind speed will be more accurate.
      It would be nicest to add a directional vane to option #2 for the best of both.
      I'll attempt a crude visual -- apologies in advance! ;)

      Where the vane is free to rotate on it's own from the cups.

    17. John Ross on

      Speed & direction, please.

    18. M. Peng Chansakulporn on

      Option #2, agree with Justin's comment. For option #1, the wind speed accuracy depends on the wind direction accuracy. Unless 1) it is a pole mount and in the open area and 2) the tail size is larger or sensor rotational resistance is none for low wind speed, then option #1 would not be viable.

      Justin on

      I had another weather station with the combined speed/direction style sensor and it didn't work well at all. In an open space with no turbulence, it'll work fine. In a more realistic environment, the turbulence causes the vane to swing around wildly and the impeller spends very little time facing into the wind. As a result, the wind speed readings are only a fraction of the constant and gust speeds. I would strongly recommend not using this design. Given the two choices, I advocate for Option 2 since Option 1 will be useless in most scenarios. Also, wind direction (and speed most of the time) will always be useless if the sensor is mounted to a wall.

      Dumas on

      I would not trust the wind direction from a device attached to a wall. Option 2 with only the wind speed would be very usefull. And the design is nicer ! Plus an option should not be too high in price.

      John Booth on

      Option #1 so long as it is pole mounted. The wind direction is important information here in Florida during the passage of a hurricane. (Which raises the question of the maximum wind speed survival of the sensor.)

    22. Stefano Lippolis on

      Option 1 with the design of the option 2 and pole mount possibility. Thanks for your effort.

      Franklin Pond on

      Option 2 - direction would not be accurate when mounted on a vertical surface which blanks up to 180˚.

    24. Missing avatar

      Eric Koerner

      option 1

    25. kokobin

      Option 1, obviously

    26. RonF

      Option 1

    27. Xuntar on

      Why not something like this that can measure both speed and direction in the same size as option #2?

    28. Missing avatar

      Vito Tonarelli on

      Option #1, but pole mount is a must!

    29. Missing avatar

      Chris on

      Option 1, speed and direction are both important and as others have said it needs a pole mount - wall is not good.

      Just need a tipping rain gauge and it will be a great solution.

      Luis Gabriel Homocianu on

      A wind sensor that measure the speed and direction would be the best choice. But you must keep in mind the price to, we do not want it to cost a little fortune. Also, an ultrasonic wind sensor would be nice, it might be cheaper and better.

      Pierre Hansson on

      Option #2 with wind direction! But must be able to mount it on a pole, not just on the wall!

    32. Missing avatar

      Chiman Choi

      Option 1

    33. Missing avatar

      Roderick on

      Option 1, but only if there isn't a significant trade off in accuracy and durability...

    34. Mike Krueger on

      Option 1 without a doubt. Wind direction is very important despite what some people might think. It's true, it can't be mounted on the side of the house but needs to at least be mounted on the roof to get the wind in all directions. Now if we could convince you to work on a tipping rain gauge. :-)

    35. Craig Nimmo on

      I agree that a vertical mount needs to exist to allow usable data for direction of Option 1 is to succeed. I would prefer direction to be included, but it will be false data unless it is able to be in a free area.

      Option 2 is more viable from the designs, so if no redesign is to occur, then option 2 please.

    36. Christophe Loizeau on

      I would say Both as it really depends in which environment they will be put in place. Near a house option 1 is useless but in the middle of large garden it can be interesting depending the wifi coverage. Btw have you thing to add z-wave communication to integrate that sensor into the home automation too, can be a great advantage to combine both services !

    37. John Livesey

      Option #1, with a pole hoisting the anemometer well above the solar panel (as suggested in several earlier comments).

    38. Robert Khoe

      Option 1, but whichever it will be: pole mountable and the sensor and solar receptor should be way apart to get any useful read ...
