How to capture telegrams for clock program

[HansRemmerswaal]

The EMS-ESP32 supports most of the menu options of my boiler / thermostat, great job! The only (?) option missing is the clock program for hot water. I always assumed that this option is missing in EMS-ESP32 as this clock program was not published on the EMS bus. But I was wrong. I installed Bosch EasyControl and via the related app I can read and change the clock program. So there are telegrams to read and update this clock program.

I monitored the EMS bus while changing the clock program, but there are so many messages on the EMS bus that I have no clue how to find the ones triggered by the changes I did.

1. If I figure out the telegrams, is this then something you want to implement in the EMS-ESP32?
2. What is the best way to monitor the specific telegrams? How to filter, how to interpretate the telegrams?

Below is how it looks like in the Bosch EasyControl app. This is showing and updating the clock program in the Enviline itself.

Getting EMS-ESP as close to the Bosch App has always been one of my goals, so yes, if we can build the clock feature we should.

The issue, though, has always been whether the Master (boiler) actually holds the clock schedule, or is just the Bosch App syncing with the Bosch Cloud and then instructing the CT200/Easy thermostat to switch on/off at the right times. I think the later.

see #1594, #1918 and some more..
I had a branch with the timer- and holiday-scheduls published as extra json, but deleted it after 2 years.
For normal implementation with each value as entity it's too much entities (42 datasets with day, time, mode, temperature, hcs, dhw).

For telegrams see https://emsesp.org/ems-library 0.02C3, 0x02FF, 0x0309, 0x043F, 0x0449, 0x0683, 0x068D

It updates directly in the boiler. When I change something then I do see the change when I navigate to the menu option.

Why do we need extra JSON if this is stored in the Boiler itself?
Looks like that in the 0x02FF it's already mapped out. So not needed for me to investigate.

@MichaelDvP we could start by reading the clock programs and displaying them in the WebUI?
