Unable to get/set schedule.

[jszkiela72]

Is there an existing issue for this?

• I have searched the existing issues

I'm having the following issue:

1. When I run the "Plum ecoMAX: get_schedule" service for heating, the integration returns all values as "day". This is not correct because in the controller I have it set from 00.00 to 06.00 "night" from 6.00 to 15.00 "day" from 15.00 to 00.00 "night" "
   I can't save the schedule to the controller using the Plum ecoMAX service: set_schedule" for heating.

2. When I run the "Plum ecoMAX: get_schedule" service for water heater, the integration returns the correct values.
   But I can't save the schedule to the controller using the Plum ecoMAX service: set_schedule" for the water heater.

I have following devices connected:

• ecoMAX 3xx series
• ecoMAX 8xx series
• ecoMAX 9xx series
• Expansion module B
• Expansion module C
• ecoSTER 200/ecoSTER Touch
• ecoLAMBDA
• ecoNET 300

I'm connecting to my devices using:

Ethernet/WiFi to RS-485 converter

I'm seeing following log messages:

No response

From your diagnostics the issue is not related to the integration, but to the PyPlumIO library, which handles low-level protocol.

From a few cues, such as incorrect fuel level, missing model string and partially working schedules, it seems that Plum changed structure of related frames for your model. As PyPlumIO was initially writen for ecoMAX 850P in 2022, changes in firmware done by Plum in further models/firmwares can break the library's ability to decode frames.

This prompts future reverse-engineering of what changed in your device firmware. I'll get to it on the weekends, hovewer it will most likely take more than couple days. Sorry for inconvenience!

[jszkiela72]

I confirm that my controller is ecoMAX 860P6-O. If I can help you with anything, write please.

Just so that I have somewhere to start, could you please elaborate if there any errors, when trying to set water heater schedule using set_schedule service or it just silently fails?

[jszkiela72]

Hi There are no errors after calling the service. There are no errors in the HA logs. Regards, Jarek śr., 13 gru 2023 o 02:37 Denis Paavilainen ***@***.***> napisał(a):

This is not good :(

If you still want to help and know how to run arbitrary python scripts, could you please run one below and send me schedules.json file that it'll produce.

If you don't know how to run python scripts or not comfortable with doing so, don't worry, I'll still try to solve this issue, it's just gonna take more time.

If you decided to help, this simple heavily-commented script will simply send a request for schedules to your boiler and once it'll get a response, it'll save raw bytes and decoded data into JSON file. This way I can obtain raw bytes of the schedule response from your device and try to deduce why it is decoded incorrectly.

Don't forget to install PyPlumIO via pip before running this script:

$ pip install pyplumio

and set HOST and PORT variables to point to your converter.

It doesn't send it to me, it simply writes it to the file named schedules.json next to the script itself. If you managed to run the script, please send me this file yourself, it will be very helpful, since I'll then have an undecoded bytes from your device and can then implement changes into decoder and test it right away using this data.

[jszkiela72]

schedules.json

[denpamusic]

Thank you very much for your help! I'll plug this data into a test case and try to rewrite decoder until it matches this for heating schedule:

This is not correct because in the controller I have it set from 00.00 to 06.00 "night" from 6.00 to 15.00 "day" from 15.00 to 00.00 "night" "

[jszkiela72]

Hi,

Today I had more time to look at the schedules. I have to apologize to you because I misled you earlier.
I will divide my explanation into two topics.

1. DHW schedule.

I once wrote to you that I can read the DHW schedule, but I cannot set it. It turned out that I could set it up, but I was doing it incorrectly. This is because, before I installed the integration, I had set a schedule on my room panel (ecoMAX 860P Touch) for: 00.00-06.00 night (means do not heat the water), 06.00-15.00 day (heat water), 15.00-24.00 night. Then I started the service and set, for example, 12.00-14.00 day. There was no change on the room panel so I thought the service was not working properly. Now I know that to set water heating between 12.00-14.00 I should call the service 06.00-11.30 night and the second service 14.00-15.00 night. Alternatively 00.00:23.30 night and then 12.00-13.30 day. I don't know how to do it in Lovelace yet - maybe you can tell me something ;)

2. CH schedule.

As I wrote earlier here, I could neither read nor save the schedule. Today I noticed that Plum ecoMAX 860P6-O + Plum ecoMAX 860P6-O TOUCH has two schedules for CH. One is in the pellet boiler and the other in the room panel. They are independent and their settings do not overlap. I checked that I use the service to set the schedule in the pellet boiler, but I don't use it (it's turned off), I use the one in the room panel. Tell me, are you able to improve the integration so that it allows you to change the schedule in the room panel?

If something is not clear to you, do not hesitate to ask.

Regards, Jarek

Hi!

Thank you for the clarification!

1. It's ok. Schedule services documentation are quite bad and need improvement, so it's no wonder you've got confused. Furthermore there's no easy way to use schedules with lovelace, because such card doesn't exist. The best possible way for now would probably to create separate datetime helpers for start of night mode and start of day mode and create a script that will parse those inputs and send it to the set_schedule service. I could try to create a HASS blueprint for such use case, I wanted to learn how to use them anyways.

2. As for heating schedule, you are right, PyPlumIO only knows how to handle ecoMAX schedules. ecoSTER panel schedules is requested with different request frame REQUEST_GET_ECOSTER_SCHEDULES[frame_type=88] which is unsupported by PyPlumIO yet, but shouldn't be very hard to implement since frame format should be literally the same as ecoMAX schedules. Could you please run another script for me. This one should request ecoSTER panel schedules and write them to schedules.json file same as before. This script is a bit larger, since we're trying to get a frame not yet supported by the library. Don't forget to change HOST and PORT variables.

Hi

There is some problem with this script.

When I run it, in the terminal I have:

Requesting ecoSTER schedules form tne ecoMAX...
wait for response...

The script doesn't end. On the RS485 to ethernet converter page, I see that the script is trying to send data, but ecoMAX returns only 10 bytes of data.

I checked, the previous script executes correctly, so it's not a hardware fault.
