Can I use Domoticz with Onewire sensors?

[rowanbradley]

I have just installed Domoticz, so am early in the learning process. Can I use it to read temperatures from a OneWire (Dallas/Maxim protocol) sensor? I have a DS9490R USB to OneWire adapter (which I think creates a virtual serial port). Do I need any additional hardware or software to make this work? If so, where do I get it from?

If this doesn't exist at present, can I write a driver for the OneWire temp sensor? What is involved in this? What tool chain do I need, what language do I write in, are there documents explaining what I have to code in the driver?

Thanks - Rowan

Did you search the forum already? There is a lot of information about OneWire support

Yes, I tried. Much of the information in the forum is concerned with running on an Arduino or a Rasp-Pi, which is (I imagine) very different to trying to run on Windows, which I am. If there is a relevant discussion that will help me, please can you point me to it?

As far as I can see there is no 1-wire interface to domoticz for Windows, you need a raspberry PI for that. I'm not 100% sure when you add a domoticz slave (raspberry PI with 1-wrie) will work.

Surely some people would find this useful?

Surely it can't be that difficult to do? I can use the DS9490R USB-to-OneWire interface, which I believe emulates a serial port...

If it doesn't exist, can I write this extension to Domoticz myself? Is there some documentation and sample code for starting Domoticz development? What tool chain do I need to use? What language do I need to write in?

Yes you can, it's an open source project https://github.com/domoticz/domoticz

See https://github.com/domoticz/domoticz, language is C++

Have you checked out the Domoyicz wiki? I used to have 1-wire working under Windows. (Replaced now with Z-wave Fibaro module which accepts the 1-wire temperature sensors).

I just checked the Wiki. It told me where to find a file called OneWireDomoticzServiceInstaller.msi, but when I go to this location, there is no such file. Where do I find this file?

Have sent you a PM.

Hi,

I'm in the same situation as Rowan. Have also find the link/information about OneWireDomoticzServiceInstaller.msi but no file. Did the PM sent to Rowan solved the problem? Any information that can be shared to others with the same problem?

BR,

Akost

Thanks for your PM Rowan,

I'm not allowed to send any PM (yet?) but I will let you know how I get on with the 1-wire. If weather is poor here in Sweden I will have some time over for some testing...

Thanks
