Individual Room Control ELV the MAX!

[jrkalf]

elv MAX! is one of the ways to do individual heating control of rooms.

In this sub forums you'll also find a solution called FHT. Created by the same company with some more extensive capabilities.
Depending on your choice of product of functional requirements either can be nice ways of central heating controlled on a room level.

FHT is currently remote controllable by using a CUNO/FHZ device which is has a layer of FHEM on top. However, the creator of DomotiGa is currently implementing FS20/FHT support into it's management suite. So it might be a viable option as well.


One thing I don't know about the MAX! system, perhaps one of the owners can tell me: Does it work autonomously? I get the feeling you need that MAX! base system which controls all the actuators and it requirs constant power from the wall.

The FHT system is battery powered (lasting up to 2yrs per charge) and works without a central system coordinating it and requiring constant power from a computer or wallsocket.

I don't even have the hardware yet, so I'm not going to answer until I can say something based on my own findings.
In the mean time, maybe a search engine can help??? It might also be wise to check www.elv.de and/or www.eq-3.de

Digit,

I have maybe found the decoding of the date. I will check this evening if I'm right, I have currently 1 date which doesn't fit in the logic I have found, but maybe that was a wrong reading...

it looks like:

Code: Select all

Date (DDMM): 2908 (29th of August)
HEX: 9D0B
Binair: 1001 1101 0000 1011
decode: MMMD DDDD DM?? ????
MMMM: 1000 = 8
DDDDD: 11101 = 29

Cool No MAX! for me this evening, another work in progress needs my attention; leave something to discover for me, will ya

[blb]

...leave something to discover for me, will ya

I'll try

My MAX! is on the way too from ELV, arriving same time as digits.
I dont mind that you guys find all the bytes, enough on my ToDo

[jrkalf]

seems like people are starting to like the ELV goods:)
Will this coding attempt make it into the DomotiGa tree as well?

if all works Ron will pick it up I guess

[jrkalf]

*slightly offtopic*
Ron's currently doing a hell of a job coding without having hardware and only having remote access to hardware

I mean, he has the controlling interface (CUNO), but not FS20/FHT modules. He's doing a lot by replaying logfiles and making it work that way

Yeah, I also use PIR13 and some small enclosures from ELV
There's not much useful coding done yet; I did prepare a tool for decoding stuff though.
And there's still a lot to do; battery status, daylight saving, schedules etc...

Hi blb,

Code: Select all

Date (DDMM): 2908 (29th of August)
HEX: 9D0B
Binair: 1001 1101 0000 1011
decode: MMMD DDDD DM?? ????
MMMM: 1000 = 8
DDDDD: 11101 = 29

And the last nibble is the year-2000.

To ensure that we're not working on the same thing - I'm already making good progress on the H:-, M:- and C:-responses, of which examples are shown here: viewtopic.php?f=66&t=6239&start=15#p50494
I'll try to post what I found out later this evening.

[Bwired]

i think its good to start a seprate post here with explaining the protocol, like we did for Visonic
BTW: My first (and for now only) valvue (radiatorkraan) is back to ELV, it would not callibrate, giving constantly F2

[Digit]

Hi there,
I started a post for the protocol info, here: viewtopic.php?f=66&t=6654&start=0
It will constantly be updated with new information when it becomes available.
Enjoy

Thanks Digit!
