Are you using an outside weather station? If so, which one?

Correct, both for solar charging and UV sensor. It provides it’s own shade where it needs it.

That’s why more expensive weather stations come with an GPS module for time synchronization.
but yeah, I guess, WU somehow uses the timezone (or that one of your location?) for time updates; I got the info from various posts on the station as they all confirm: time only comes with WU-integration.

Those GPS timed stations are designed to sit in the middle of nowhere and are designed to record data for weeks or months until someone shows up and downloads the collected data, different thing.

This station (ws140x/wh260x) needs to be connected to the net in order to function (it doesn’t have internal storage), so - since that’s the case - why not use NTP?

Time only enters the picture if you store the data over time. This station by itself isn’t doing that, it’s just a bunch of sensor values updated at a certain frequency. You’ll need WU (or perhaps OHAB2 + my binding + a DB) to have values stored over time (with a time stamp).

Not entirely sure what the fuzz about “missing time” is.

I flashed the latest v4 Software from ambient on the wh2600 … Same Hardware. Works. Only Ambient offers current Firmware as Download.

No
without WU you Just use the http Binding and regex to get regular Updates from the local Station.
I can Share the items to do this 100% local and Cloud WU free

I recommend Weatherflow Station https://www.indiegogo.com/projects/weatherflow-smart-weather-stations/x/13825996#/
Way better quality of measurements than toys like Netatmo and it has local API!
Bill Welliver has already developed binding for the station itself and also for calculations

I don’t think that’s the reason. Most middle-priced (and top-priced) stations are GPS timed - nearly all KNX-station do (and I don’t think there’s KNX in the middle of nowhere! :wink:

That’s a question of firmware - I guess not enough space on the RAM for this. You must consider, those weather stations are not the latest state-of-the-art versions, RAM was expensive in the last century! :wink:

That’s exactly the point. If you’re using the station not merely “for fun”, but for some (hopefully non-vital!) logic purposes, you have to be sure, the data is accurate - and up-to-date. That’s why we’re discussing time here! :wink: From what I’ve read, the WS140x/WH260x tells you via livedata.htm.

would be worth a try - as far as I can see, there are no mechanical parts for wind or rain measurements (which is supergood!), wind is clear, but I’m curious how the rain gauge works?

provides hourly rate & daily accumulation at 0.2mm resolution

Do you have one? and can tell how it works? :wink:

edit: ah I finally saw the vide, which explained it…

I do the same thing and catch the data locally … but I also then send it on to WU too.

I do the same.
But in OH I use only the local data.

The company that makes the weather stations that then get rebranded by different companies is called “fine offset”. For example this is my station linked to the fine offset website, but my unit has the brand Pantech written on it.

http://www.foshk.com/wifi_weather_station/wh2950.html

You will find all the models with features, manuals and firmwares at that website if you wish to compare models from the manufacturer. But if shopping for one the basic choice is one of three options.

  1. Data uploaded to WU by the ugly black box. Cheapest way to buy one, but you miss data if it does not reach WU (more on this below). Example http://www.foshk.com/cables/WH2600.html

  2. Data uploaded to WU by a console model that can draw a graph so this costs more. I think this model is the one.
    http://www.foshk.com/Wifi_Weather_Station/HP1000.html

  3. Data uploaded to WU by a console with no graphing features. Mine is this option and is the cheapest way to buy one in my country with a screen to check if WU is missing data.

All the outdoor units can have the rf packets intercepted as well as another project that can grab the data if you redirect the wunderground packets to a script.

Weewx GIT project: How to get data from a HP1000/WH2600 weather station

Also it is interesting to note a company sells just the outdoor unit with RS485 output on ebay. The outdoor unit just has a basic serial to RF chip in it that sends unencypted serial packets to the indoor display or the observer IP unit. You can hack into these serial packets to get the data direct from the outdoor unit which is something I plan to do in 2+ years time when I get a lot of other projects done.

The above linked weewx is worth looking at because these units have a flaw. If your WIFI goes down due to a storm (right when you are interested in looking at the rain data) the data never gets to wunderground and never gets uploaded when it reconnects. Your indoor unit shows rain that you got that the wunderground site does not show. I read that the weewx does allow you to detect this and upload missing data but have not looked at it in depth yet, see http://www.weewx.com/wunderfixer

The weatherflow product looks indeed really interesting, as non mechanical, with API etc.
However does anyone actually have any experience with it? They state, that the device is in production stage and hasn’t been delivered yet?

seems there a whole bunch of users here already - and if I read correctly on the Website, there are already 2000 devices out there.

Most of backers have already got HUB + Air (including myself). We all wait for Sky (wind, rain, UV).
As to the Air I can say that it works flawlessly and provides very precise measurements and the binding developed for OpanHAB by Bill Welliver works very well.
The question would be if we have here in OpenHAB community someone having Sky test unit, able to say few words about it.

I’m using Ambient Weather WS-2902 to be honest, im loving it. Especially their customer support is great, they answered my silly questions. This website has all type of reviews to help you choosing the right weather station https://www.weatherstationlab.com/reviews/

I use WH1080 it works okey but where a little problem to access data from my logging software. Now i changed logger to wfrog and that works nkxe but havent come to import data to openhab from there yet

@jardon, how do you connect it to OH (are using the Ambient Weather WS-1400IP Binding)?
I do not want the station to send info out of my local network (e.g. to WU), is that possible?
Any info appreciated.

If it helps anyone.

I have this installed and connected to OpenHab2

Velbus Meteo / Weather Station

FYI, I am using a WH2950, am locally overwriting DNS of rtupdate.wunderground.com to my local server and have a small script (in golang) running that converts the http request to mqtt for OH2 to consume.
