thanks
I see sensors in devices and sensors are added as used.

How to add Max! wall sensors or radiator sensors to floor plan ?
I see sensors in devices and sensors are added as used. but in room plan edit I see only devices from rflink. Thanks for help

Hiya, 
The ELV Max! isn't (yet) seen directly by domoticz. You need to create a dummy device in hardware, mine is called "EQ3" and note its idx (left column) then in the .maxbuddy/scripts folder, edit the .js file to your ip/port and the dummy idx/HID.
See here viewtopic.php?f=34&t=841&start=20#p15912 for some better advice/tips.
Then your ELV Max! devices should start to show in devices. A word of advice, add them one at a time so that you know which is which.

Hi all,
I'm starting to be able to read directly from the Cube using Lua and a tcp socket.
So far I can get the Cube's raw response - next to decode it in Lua.
Then to try sending an 's' command.
Huge thanks to whoever wrote the PiHeating Python code, it really got me started.

Wow Westcott!
Great to hear. This section has been so lifeless recently that I almost ( almost ) decided to look into Evo Home
I look forward to seeing how you get on and trying it

Any news on this Westcott? I would love to have direct support for the Cube in Domoticz. Most other main home automation packages have it, and I really think it could boost interest in both Domoticz and the ELV Max! System.Westcott wrote:Hi all,

Once you have something beta ready, I would be more than happy to help you test it.
P.S. I think I saw the code for the ELV Max! Cube binding for OpenHAB somewhere, they already worked out all the decoding. Maybe this can help? If I was a programmer myself, and if I had more time, I would have loved to help myself...
EDIT: it's at https://github.com/openhab/openhab/tree ... ng.maxcube

Hi Mvzut,
Thanks for your interest!
My Cube broke, it wouldn't power up any more.
I've returned it to Conrad, but no response yet.
Thanks for the OpenHab mention, yes I've found a couple of similar descriptions.
My decoding of a single valve is almost complete.
Once I get a working Cube again, I can move to sending commands.

I think you'll find more than 1 waiting with interest
I'm holding my breath!

Hi all of you holding your breaths,
If I post some code here, could you try it for me, please?
Unfortunately there is quite a bit of setup first, to get the necessary Lua libraries installed.

OK, here we go.
I think this is how I did it...
First you need to update Lua to 5.2.
Then get the 'lua-socket' library, and the 'luarocks' installer/manager app.
Finally some 'luarocks' need to be installed.
The last step is a list of the installed 'rocks'.
Each step has to be successful before the next can run, I had a +lot+ of Googling to do here, and might have forgotten some bits.

Code: Select all
sudo apt-get install lua5.2
sudo apt-get install lua-socket
sudo apt-get install luarocks
sudo luarocks install luasec
sudo luarocks install luasocket
sudo luarocks install basexx

I got stuck at the installation of the luasec rock, it complained about openssl.a or openssl.so or openssl.so.* not found. Openssl is installed on my system, but the files appeared to be in a non-standard location. Here's what I did to solve this:
Let us know when you have a script to test! 
Code: Select all
sudo mkdir /usr/local/ssl
sudo cp /usr/lib/arm-linux-gnueabihf/libssl.* /usr/local/ssl
sudo luarocks install luasec OPENSSL_LIBDIR=/usr/local/sslRe: ELV Max! Heating control system
Posted: Sunday 22 May 2016 21:45
Nice one!
This might also work, before luasec -
sudo apt-get install libssl-dev

Another possible way, watch out for the reverse quotes -
sudo luarocks install luasec OPENSSL_LIBDIR=/usr/lib/`gcc -print-multiarch`
sudo luarocks install luasec OPENSSL_LIBDIR=/usr/lib/`gcc -print-multiarch`

OK, but my solution was also ok, right? At least I have eveything installed now.Westcott wrote:Another possible way, watch out for the reverse quotes -

Hi again,
Just installed the lua libraries (same install problem) all good to go

Gosh, that makes - um - 3 of you!
Here is some Lua code, save it to a file somewhere, and run it interactively: 'lua yourfilename'
Then please copy the result back to here, together with a brief description of your Max devices.
You'll need to put your Cube's IP name/addr in the code.
Hopefully it will read the 'L response' ("Device List") from your cube.
