I think about to by an weather station and want to integrate it into Openhab.
Which station is good to by and easy to integrate.
Where can i find add On and Binding
Want to trigger Shutters if the wind is strong or rain is starting.

I’ve been thinking of making my own with a pms5003, wind speed sensor and bme280, but an off the shelf version if decent would be appreciated as well, if there’s any around. I’m looking forward to other replies!
There are a few ways of doing this.
There is a binding for weather stations that send data wirelessly.
I have had weather station long before openhab.
Fine offset WH1081 that has WEEWX as a front end. That allows me to produce a data file that I can use to have live readings on openhab. Also just put the weewx front end in a webview.
You can also upload data to a weather site and then download it again.
There are plenty of DIY solutions with MQTT as the data sharing solution

Any dumbdumb instructions (for people like me 
) to follow on one of those examples??
I’m also looking to replace my existing weather station, where all functions but temperature and humidity has died - and it isn’t integrated into any external system.
There weren’t a lot of suggestions here, so I’m hoping there are some more inputs to be had by bumping this topic.
I’m not so worried about it being “easy to integrate”, but any cloud based solutions is out of the question. It must be a local solution.
The weather station should also be a bit robust, as it’s mounted in a very inaccessible location on the roof. The existing one is one of those “cheap” Chinese ones, and the wind sensor wore out in a couple of years (not actual bearings, just cheap plastic). Replacement of batteries is out of the question on the roof, and the solar-powered ones are just not workable where I live, where there’s hardly any light at all during the winter. The existing one were battery based, but I have mounted a power cable that is powered by an adjustable PSU (located inside), so I guess I will have to continue that solution. But, it would be preferable if the weather station was made for supplied power, since it can be hard to make sure it remains waterproof after drilling a hole for the cable to enter. Not a must though, as it’s probably very hard to find properly engineered devices that doesn’t cost a fortune.
One thing I’d also really appreciate is if the precipitation sensor had an internal heater, since a lot of the precipitation here comes as snow - which doesn’t register with an unheated precipitation sensor. But, I’ve looked for those in the past, and all I’ve found of heated sensors are ultra expensive “professional” ones, so I’m not saying that this is a must either, I’m just trying to describe my preferences/what I value.
So, in short, a weather station with some kind of local communication interface (Wi-Fi is probably the simplest, Z-wave or other radio protocols could also work) with sensors of some quality - it’s not important that the measurements are ultra precise, but that they are robust and don’t die after a short while. Heated precipitation would be a big plus.
I used a fineoffset type weather station and it transmits 433mhz. I use a sdr dongle to receive the signal and I use weather software called weewx that supports mqtt and I use that to get the information I need into openHab.
Here is my web site of the weather station:
Not wanting to be blocked for spamming from the forum, I juste wanted to mention that the RTL_433 version of OpenMQTTGateway also does recognise a good amount of weather stations through the RTL_433_ESP library, including the FineOffset ones and their rebranded AmbiWeather, Froggit etc. variants.
All compatible stations and other devices are listed at
And with @ccutrer’s great advances with MQTT auto-discovery they should all be auto-discovered as well soon.
Thanks for the info guys. My existing (broken) weather station is also one of those Wxxxx (can’t remember) 433MHz models - and I know that you can use dongles to intercept the signal. It’s good to see concrete suggestions of how to do this though, as I haven’t looked at that for a very long time.
But, the quality of these stations are just terrible. The sensors are just cheap plastic without proper seals or bearings. So, as I need to use a lift to get access to the sensors on the roof, I was hoping that I could find something that was a bit better quality, so I don’t have to “repair it” all the time. Are there different manufacturers that use this 433MHz system, or do all these devices originate from the same, low quality, manufacturer?
All I know is that Ecowitt, Froggit and Ambiweather stations are all rebrands of Fine Offset stations, in 433MHZ, 868MHz and 915MHz versions, depending on regions/countries - at least their consumer models. They all look the same anyway, so easily identifiable. They are all also receivable and decodable through Fine Offset decoders.
If the companies’ other more pro models are any different in their built quality I really don’t know, nor do I know if there might not be more rebranded Fine Offset ones under even more different brand names.

I know the quality isn’t that great but it does what I need.
The only thing that is annoying is every time I am away the rain gauge doesn’t work because spiders make their web around the rain tipper bucket.
Yes, mine stopped working (back when it actually worked) constantly because of snow and ice. I know that heated rain sensors exists - but I’ve only found very expensive ones.
Another option would be to get separate devices to build your own complete weather station, a separate Rain Gauge, Hygro- Thermometer, Wind sensor … so if one fails you still have the other ones and only need to replace a single item.
Have a look at the linked to decoders above, LaCrosse does them as separate items for example.
Yes, that would be fine for me, except that it usually means a much higher total price. And, they would need to communicate using the same system. But, primarily, I’d wish to not have to get up there at all. During winter, it isn’t feasible to get a lift there at all, so when it stops working it will have to wait for spring. It really shouldn’t be that hard to make something that can withstand the weather. Maybe I’ll have to make my own watertight steel casing around the whole thing, but it’s problematic to get a tight seal around the wind sensor without introducing friction that slows it down.
I should probably discuss this at one of the “weatherstation forums” instead, when it comes to the quality/robustness of the sensors.

Humm any 868mhz work on this??
Humm any 868mhz work on this??
Yes, my Froggit Fine Offset rebrand weather station is actually a 868MHz FSK one, and I’d working fine.
The linked lists above only differentiates between OOK and FSK modulation, where within both there might be 433, 868 and/or 915 MHz devices.
The only thing to watch out for is to get an appropriate frequency board, e.g. LilyGo/Heltec, or separate CC1101 radio when using a generic ESP32 to match the frequency of your device(s).
Any particular station your have or are interested in which is 868MHz, and have you seen a decoder for it in the list?
It looks like the one I’ve got is a FineOffset WN1090, and its sensors are just crap that only lasts for a short while. None of the “similar models” are very interesting.
I have had several weather stations for over 20 years. Some, my own designs, some good sensors from here or there and some low quality all in one stations. I finally bit the bullet and went with a Davis Vantage Pro. 2. It has been running without issues for 6 years. Sure, it is expensive but its a quality product. The plastic is holding up great, unlike some of the others I have had. The only maintenance I have to do is occasionally clean the rain bucket because birds like to use it as a toilet.

It’s way beyond what I’m prepared to pay though 
I completely understand. You might check out [WXforum.net - Index]. A group of weather enthusiasts that have some great ideas.

Oooh… you’re making me enthusiastic now @Nadahar .
Yes I have a 7 in 1 bresser weather station. The one on the list is the 3 in 1 but the communication is fully decoded here:
Would it be possible to add the others??
