Extension of boiler data with usage data about ems-esp32

[MichaelDvP]

Did not find broken things till now. Works good.
Trying to merge the boiler extension now (needs some manual editing).
Not sure how to format the times, see #16

@MichaelDvP I just checked the values that are shown in EMS-ESP and compared them to the values I see on the boiler: exactly the same!!!

[viimD]

wow, great find! In my Nefit heatpump app i can see the energy usage (only in a very not useful graph), so the figures must be there indeed!

[MichaelDvP]

I've merged it to my local dev. Needs some smaller changes to fit to the dev branch and some corrections, but compiles now.
@proddy should i push?
@replayed can you provide some raw telegrams for the test-routines.

[proddy]

@MichaelDvP could you wait a day. I have about 30+ changes waiting to push

[replayed]

@MichaelDvP Attached are two files for raw data for the 494 and 495 telegrams. Let me know if you need additional data.

ems-esp - raw data telegram 0x495.txt
ems-esp - raw data telegram 0x494.txt

I did my push, probably broke lots of things but we'll see. @MichaelDvP over to you....

@replayed , @viimD
Can you please check the new dev build. My boiler does not have these values.

[replayed]

@MichaelDvP
Just uploaded the b6 development build. It's running now and all values are being output correctly. I will have to let it run a while to check changes in more values.

Probably unrelated but the Dashboard / Devices & Sensors pages does not show latest values anymore. Only separator lines are visible (see image below).

[MichaelDvP]

Maybe confusion with cached b5 page? Try reload the webpage.
Have you flashed the bin from https://github.com/proddy/EMS-ESP/releases/tag/dev or compiled self?

[replayed]

Correct, a forced page update fixed the issue.

And i used the compiled bin from https://github.com/proddy/EMS-ESP/releases/tag/dev.

@MichaelDvP
After monitoring for a few days all values are consistently being handled correctly. Small issue is that all uptime source values are in seconds and the webpage shows the values interpreted as minutes.

[MichaelDvP]

@replayed keep the unit minutes and show value/60, is this ok, or display the values with unit seconds?

[replayed]

@MichaelDvP
Indeed keep the unit in minutes and show value/60.

Is the usage data feature already part of a firmware package? My ESP says esp32/v3.2.3-14-gd3e562907, HA shows only shows zeros and I have no clue how to find the info in github.

[proddy]

@swa72 some of it is there. Check with the console using the show command. Top line is the version of EMS-ESP.

[swa72]

Yupp, After replacing the ESP8266 with the ESP32 I'm on EMS-ESP version 3.0.0b1 and the device just rocks :-)

[glitter-ball]

That’s good news. Bought an ESP32 to put in my gateway - maybe this week. Just need some time to solder the headers on and flash it.

I've seen the solar energy data and some operating times.

Would be cool if users could read out energy consumption of the burner/warm-water (the same data as the RC300 shows, if you tap on "Info" and scroll down to last entry "usage data" or something. It lists you the energy consumed for the boiler (gas, electricity), warm water (gas, electricity) among others for the last 24h and the last 30d. Plotting that data would be really cool :-)

that would be interesting. There's been some talk about this before (#91) and also quite a bit in the old Gitter chat room. In theory if the RC300 can do this, so can EMS-ESP. It'll be a nice project. I only have a old RC20 so can't help much!

[swa72]

I‘m wiling to beta test. Question is, does the RC300 receive the energy consumption data or does it calculate it given other data? And if so, which?

[swa72]

I've had a chat with a buderus guy on the the phone the other day: usage data in RC300 is guesstimated - so no reliable info. In the meantime, I've setup an ESP32 device to monitor my gas meter (https://github.com/swa72/home-assistant/blob/main/esphome/README-gas.md).
