compatible is 1-wire sensors ?

Post by tparvais »

Hello

Is meteohub able to collect and use also data collected from 1-Wire sensors, connected via USB Key interface ?

For rain gauge, T°, pressure,.... all sensors available on www.hobby-board.com

Thank you

Thomas

Hi, I've just started experimenting with this idea. Meteohub can't pull data from the 1-wire sensors directly, so I'm trying to build a "link". I'm using OWFS (OneWireFileSystem) to read the sensors, then a script to read the OWFS data and map it to the same format as the meteohub "raw" file. Then meteohub should be able to read it.
I say "should" because I've only just started playing with this. I'll let you know how I go (but history suggests it will take me a long time...).

Hello

I saw many new release of MeteoHub. Still no plan to implement 1-wire interface in native mode ?

Thank you

Not geoff, but I am successfully reading a few 1-wire sensors (temp, humidity & pressure) using a meteohub 'plug-in' I have written (using owfs to 'talk' to the sensors).
The plug-in is nowhere near ready for "public consumption" due to shortage of spare time for its further development, but it does at least demonstrate that the basic idea is practical.

skyewright, you have to get your priorities straight :)

But seriously, do you think their will be a time when it is ready for "public consumption"?

Thanks

I hope so, but I can't offer any guarantees or time scales.

I hope so too :)

I need my lightning sensor back online... the season already started here in Colorado.

I got a lightning sensor about a month ago, so that device is on my to-do list :), but haven't even had time to wire it up, let alone add it to my "proof of concept" plug-in yet ( however it's essentially "just a counter" ;) ).

Out of interest, what hardware do you run Meteohub on?
NSLU2, or one of the x86 options?

That would be a x86 platform

Well, I have my lightning detector wired up now (only in the office, so it's mainly just detecting equipment being turned on!), and I'm still playing with how best to graph it but if that's your main interest and you'd be happy to take part in an experiment involving you logging into your Meteohub via SSH and following a 'recipe' you might like to contact me off Forum (there is a Contact link in the footer at the bottom of my website).

Is there any news in the integration of 1-wire sensors with meteohub ?

Hi you all,

I also would like to ask, if there are some news in 1-wire support.
I'm running my station for nearly 4 years, I'm using WD on old notebook. Because that notebook seems to have slowly started failing and also I'd like to save some space and energy, I'd like to switch to Sheeva (which I already have) and Meteohub. But, since I have three sensors on 1-wire apart from my WS2300 and also in future I thought to have my meteo station completely on 1-wire, the support of 1-wire sensors is a bit critical for me.

So, I don't know right now if author of Meteohub has at least some plans of implementing 1-wire directly, or if there is some other working way to put my sensors data to Meteohub, so I can start playing with converting my four years of WD data ;-)

Thank you in advance!

I can't speak for Boris, but a significant factor is likely to be that 1-wire is compeltely unlike other weather stations in concept. 'Normal' weather stations have a fixed purpose and provide a restricted set of data in a closely defined manner. 1-wire on the other hand is essentially a kit of low level parts that can be handled and combined pretty much how you want. The DS1820 temp sensors are relatively straight forward, but beyond that it's often a case of measuring one or more parameters and adjusting or combining them in various ways to represent various weather attributes. For example I'm aware of at least 4 distinctly different anemometer set ups!

I've managed an OWFS based meteohub plug-in and it works but it is very much a custom thing. Making it generic would require far more time than I can find. It may be that the most practical solution would be a meteohub plug-in that took output from one of the existing 1-wire systems and presented it to the meteohub system.
