Does anybody here know the internal protocol between cube and valve components? I can't seem to find it anywhere, is it FHT based or completely different?

Re: ELV MAX! protocol description
Excellent! Thank you!
Re: ELV MAX! protocol description
i really can't see the advantage of bypassing the cube (except the €30 not spent, obviously ).. could you please explain me?
Re: ELV MAX! protocol description
Hi,
this is my first post and came across this very interesting topic.
Has anyone tried the protocol on Ethernet socket base with a wago controller 750-880 implemented.

Re: ELV MAX! protocol description
Hello,
Regarding wall thermostat (device type = 3), the L message contains 12 bytes. Length is 12 (of course ) and last byte represents the real temperature x 10.
0xaf => 175 => 17,5 degrees

Re: ELV MAX! protocol description
Don't know if you have a new type wall thermostat Philippe, but my wall thermostat L message is 7 bytes long whereas the actual temperature is represented by the MSB bit of the third byte together with the seventh byte ( x 10).philjung77 wrote:Hello,

Re: ELV MAX! protocol description
12th byte is actual temp*10, so theres a limit: 25,5 degrees. if it's higher, the count starts from 0 again and the first bit of byte 8 (set temp) is set to onepbrand wrote:Don't know if you have a new type wall thermostat Philippe, but my wall thermostat L message is 7 bytes long whereas the actual temperature is represented by the MSB bit of the third byte together with the seventh byte ( x 10).philjung77 wrote:Hello,

This is the standard wall thermostat.
I don't believe your response can be simply 7 bytes, as always it will be 6 bytes for ecoswitch, 11 for radiator thermostat and 12 for wall thermostat.
Maybe you are not counting starting bytes
1) data lenght
2,3,4) rf address
5) unknown
So then there are 7 bytes
Re: ELV MAX! protocol description
Oh silly me. You are quite right, Massi. I only looked at the specific device bytes and forgot about the generic part

For that, you need to add to you blog the protocol description of the s: command
Re: ELV MAX! protocol description
Hi,
it may be that in the new firmware 1.4.1, the commands have changed in their byte protocol?
Thanks

Re: ELV MAX! protocol description
my "simple" commands (manual temp set) still work. What commands are you referring to?mactoolz wrote:Hi,

Re: ELV MAX! protocol description
Hi,
i want to use all the commands. At least M / H / C / L and also the sending of data.
e.g. the byte arrangement of the M command I am missing some information. Rather, I do not know what type specific bytes of information again.
e.g. I have not in my receiving data, the RF address.
Look Please purely in the excel. Since I have the Empfangsdasten divided times.
You may find, for example, the RF address.
Thanks

I am running 1.4.1 firmware here and have seen no changes in the M / H / C / L messages.

Re: ELV MAX! protocol description
Hi,
have you looked at the excel. This is an excerpt from the M command. I see no RF address here. The first topic is described which can be seen in the M-command for a device address.
I do not see them unfortunately. Can you tell me the individual bytes?
Thanks
