Strange date/time holiday format

[samm-git]

Hi,

I am currently in the progress of making csv for the Protherm RC/2 module.

I wrote a script which scans all regs and by playing with device i am looking on the changes. This way i been able to identify holiday related regs, however, format is very strange. Looks like it is minutes from some event?

Could you please help?

This is a samples i collected:

09.08.19 14:20 5c 17 55 00
09.08.19 14:20 66 17 55 00
31.08.19 23:50 56 95 55 00
31.08.99 23:59 d6 9f d7 02

Funny think is that in this representation 99 year is clearly more recent date compare to 00 :)

Help is appreciated.

please post your definition of the message

Hi, i do not have yet real definition, just added it as hex parameters, see 5500 and 5700.

I see that they are changing when i am changing holiday period on the thermostat and i assume that this is time from some date (?). Also on the thermostat minimal interval for adjustment is 10m, so may be only 10th of minutes are stored

If needed i can provide you values for the different timestamps.

[samm-git]

I also provided complete configuration for that device in https://github.com/john30/ebusd-configuration/pull/140

[john30]

I guess the value is just in minutes with low byte first: 5c 17 55 00 = 5576540 56 95 55 00 = 5608790, difference value=32250, difference minutes=32250 d6 9f d7 02 = 47685590, difference value=42076800, difference minutes=42076809

[WildRat]

This format: data consists of 4 Bytes like ULG (unsigned integer, low byte first) and it's number of minutes from 00:00 at 01.01.2009. Example: 53f85f00 = 16:50:54;16.12.2020 See: https://github.com/john30/ebusd/issues/381

@WildRat good catch, thank you! Hope it will be accepted in ebusd

[WildRat]

Also, look here https://github.com/WildRat/ebusd-configuration/blob/master/ebusd-2.1.x/en/vaillant/15.e7c.csv maybe you find something useful for your thermostat.

@WildRat will do, thanks! one of the challenges i cant solve - i do have RC thermostat which has 2 parts:

1. Ebus connected radio module with some "brain", which actually managing heater using ebus commands
2. Room terminal which speaking with Radio part remotely, which actually changing thing in the ebus module

If i am overriding values from ebusctl very often they are reverted back, i think from radio. However, after number of attempts its correctly set, but this is very tricky. I think there should be some register or command to commit changes. Do you by chance had the same issue or solution to it?

[WildRat]

I have wired model and don't have this issues, so I don't know how to handle them, sorry.

[samm-git]

thank you anyway :) Will try to find some time to play more.

[john30]

the new datatype is added now

[samm-git]

Tested and works as expected, thank you, closing
