Re: Opentherm on Z-Uno

Did you had any success? I was actually planning to do the exact same! Not yet. Still have a couple of things to fix/be fixed before I can make any real progress. Among others I'm waiting for version 2.1.5 of the zuno sdk to become available. Ihor's opentherm library uses some calls not available i...

Re: HELP - cannot re-include z-uno

You may simply have to be patient. I had a similar experience once: I had accidently removed z-uno's programming before excluding it from the controller and didn't know what exactly the programming was any more. So I reset the z-uno and then forced the hardware from my controller (domoticz). In Domo...

Re: AutoPID Librairy

@poltos: I had already created a topic on that library. This was the library that doesn't compile on z-uno's 2.1.4 toolset. You replied yourself, that the header and cpp files needed to be copied into specific z-uno locations, plus that for missing functions detachInterrupt, attachInterrupt and digi...

Re: Can Z-Uno be a controler?

Z-Uno can't do the pairing procedure itself. It needs a z-wave controller for this: a z-wave controller controls the network, not one specifc device. Z-wave devices, like for example z-uno, can however make other z-wave devices do things, this is where the confusion starts: in normal live this is of...

Re: two razberry on the same wifi router

z-wave's range is limited, ethernet's (or wifi's) is not. What you could do is use 3 raspberry pi's: one in each house, each equipped with a razberry daughter card. On both you run domoticz to control only that house's z-wave devices: each house gets its own z-wave house code. Then another raspberry...

Re: Problem updating bootloader

You could try connecting using a better quality usb cable. I have some (cheap) usb cables that produce similar results. If I use one of my better quality cable, it works fine.

Re: AutoPID Librairy

I'm awaiting a port to Z-Uno too! Combined with OpenTerm library (which also needs to be ported) this makes an awesome way to create your own Z-Wave enabled thermostat.

Re: Are there any problems with using 12V DC with z-uno?

Those dc-dc converters are really dirt cheap pre-fabricated. Here's an example on ali express for 31 euro cents and no transport costs (into the Netherlands): http://nl.aliexpress.com/item/1pcs-Mini360-DC-DC-Buck-Converter-Step-Down-Module-4-75V-23V-to-1V-17V-17x11x3/32786777084.html?spm=a2g0z.searc...

Opentherm on Z-Uno

Hi all, I've set myself an ambitious goal: I want to build myself an opentherm controller that communicates via Z-wave with the thermostats in each of my house's rooms, then controls my boiler via opentherm according the heat requested by those thermostats/ The components I've selected for my projec...
