🔥 Pellet stove 'Duepi-evo'

[foux44]

Hi all,

Pretty interested to Domotize (Home Assistant) an old generation (2015) Pellet heater (De Dietrich QUADRALIS PPA 8). I only got a MiniUSB female interface at the back of the device (See Pics bellow ). I have no idea if the motherboard is a DUEPI, any idea (See below) ?

Folowing the Aceindy tutorial (Thanks), I’m using a ESP8266 NodeMCU12 with ESP-link (115200BAuds / 8N1) plug into the USB port as follow:

• Red USB wire → Vin PIN (REading only 1.5V on multimeter)
• Black USB wire → GND PIN
• Green USB wire → RX PIN (GPIO 3)
• White USB wire → GTX PIN (GPIO 1)
• ESP plug To USB external power Supply

but no reaction from the pellet heater, plug since hours without any text … Do have I get some even if it’s not a Duepi ?

Best regards,
TEd

Do have I get some even if it’s not a Duepi ?

This is explicitly written for the duepi stove.

And duepi works with question/answer.
So the esphome should initiate a question and the stove will reply with an answer.
Without the proper question, no answer either.

Since your stove is not duepi, it probably doesn’t understand the question, and therefore doesn’t reply either…

Not sure if there is an app or other software available for your stove? Without that it is practically impossible to reverse engineer the protocol…sorry

I used the original wifi app from duepi and analyzed the serial data send by the wifi module to the stove as well as the stove’s replies.
And i am quite sure there would even be more possible, but since the app doesn’t use it, there is no way for me to figure them out

Ok thanks, well I can still find another tricks did by some user: use an ESP to switch 2 resistances plugged instead of the external thermal sensor (PT100). Indeed, I can say to the motherboard, 0°C temperature ( = X Ohm), or 50°C (= Y Ohm), and use that trick as a ON / OFF event (including proper start and stop of the pellet stove)…

Hi,

First of all thanks for this awesome project. I installed an ESP-01 in my Duroflame Rembrand and after some trial and error i got i working in Home Assistant.

However, when i turn off the stove from home assistant it does not turn off but switches to “Ignition starting”. So it sounds like it is turning off, but when the stove is “cooled down” it starts again. Are there people who recognize this behaviour and what can be done to fix this?

[aceindy]

Hmm…Haven’t seen/heard of this behavior before.
What I do notice that sometimes there is a delay when turning it off and the actual status on HA, but I guess that has something to do with the

scan_interval: 30

• What is your interval set at (don’t make it too small, it might update before the stove finished replying to the previous status request)
• Does HA change the status when switching off the stove from its panel manually?

Furthermore, you can follow the status reports when turning on the debug logging:

logger:
  default: warn

[Seaborz]

Scan_interval is set to 60. The status in HA is correct, so the burner status changes when i turn it off but not to Cooling Down. I will try to get some debug logging.
Edit: enabled Debug logging but this time it didnt happen. Will keep an eye on it. At least i know debug logging is working

[Seaborz]

Ok it happened. I thought i turned it off yesterday but this morning the status was ignition starting on the stove.
The logging says a lot. At a certain moment it ran out of pellets but that status got reset every time so the loop started again.

From here this repeats

[aceindy]

Guess that would indicate something wrong with tour automation; when it has a reset, my stove goes into cooldown, and will remain off…

Do you use any automation in HA?

Or maybe, your stove works a bit different, and you should add an automation to turn off the stove when it runs out of pellets?

I just checked you logs, and indeed, this is strange:

2023-12-05 21:52:20.387 DEBUG (MainThread) [custom_components.duepi_evo.climate] Duroflame Rembrand: Received burner: Flame On, Ambient temp: 23.0, Fan speed: 1, Flu gas temp: 141, Exh fan speed: 1400, PelletSpeed: 1, Error code: All OK, Setpoint temp: 21

You could also add a safety measure, lower the setpoint to 16 degs or so, so that it might be on, but won’t start, as the setpoint is too low…

I dont use any automations other than turn off my central heating when i start the stove. It also doesnt happen all the time.
My configuration is as follows:

climate:
  - platform: duepi_evo
    name: "Duroflame Rembrand"
    host: 172.xxx.xxx.xxx
    port: 23
    scan_interval: 60
    min_temp: 20
    max_temp: 30
    auto_reset: True
    unique_id: <unique_name>
    temp_nofeedback: 16

What is the function of auto_reset? does it send a reset to the stove?
Because i see the status change form “Flame On” ->“Cooling Down”( Error code: Out of pellets)->RESET->“Ignition starting”

I am aware that i can make some automations to “fix” this, but i was wondering if i was the only one where this happened. Seems like it

@Seaborz

Seems like it

Well, it doesn’t happen at my stove for sure.

The reason i created the auto-reset is that my stove starts a very persistent beep-beep-beep when there is a fault (the stove does go into cooldown mode and turns off though).
And the beeper continues until i reset it, very annoying when the stove was started Saturday morning at 7:00 am.

What happens normally when you ran out of pellets (I mean before using it with the esphome), does it go into cooldown, and turn off?
Or does it just raise an alarm, and keeps on running?

I could add a command to turn it off after an alarm (just in case)

btw, it will only do a reset on

if self._auto_reset and self._error_code in ("Out of pellets","Ignition failure"):
            await self.remote_reset(self._error_code)

[Seaborz]

That explains why i didnt hear any beep-beep-beep last night If i remember correctly when it ran out of pellets it started beeping and i would refill it or turn it off myself. I dont recall that it turned itself off.
In the meantime i asked Duroflame what the normal behaviour should be in these scenarios.

@Seaborz

If i remember correctly when it ran out of pellets it started beeping and i would refill it or turn it off myself. I dont recall that it turned itself off.

That does explain it…

And indeed, sometimes it will sound the beeper once, sometimes it is reset before it beeps.
I have set a notification on my mobile when it resets

So the options here are:

• turn off auto-reset
• add an automation to turn it off when a reset occurs
• change the code to incorporate a ‘turn-off’ automatically (I can do that; shouldn’t be too hard)

Why can’t I find a way to put that information on the card?

this is my configuration:

climate:

• platform: duepi_evo
  name: Pelele
  host: 192.168.1.121
  port: 23
  scan_interval: 10
  min_temp: 20
  max_temp: 30

[aceindy]

Because it is not part of the duepi_evo integration?

I just use a lovelace entities card like this:

type: entities
entities:
  - entity: climate.pellet_stove
    type: attribute
    name: Burner Status
    attribute: burner_status
  - entity: climate.pellet_stove
    type: attribute
    name: Error code
    attribute: error_code
  - entity: climate.pellet_stove
    type: attribute
    name: Exhaust fan speed
    attribute: exh_fan_speed
  - entity: climate.pellet_stove
    type: attribute
    name: Flu gas temperature
    attribute: flu_gas_temp
  - entity: climate.pellet_stove
    type: attribute
    name: Pellet speed
    attribute: pellet_speed
  - entity: climate.pellet_stove
    type: attribute
    name: Power level
    attribute: power_level

Also added to readme on github:

GitHub - aceindy/Duepi_EVO: Control Duepi_evo based pellet stoves with Home...

okay… It works now!
Thank you!

Just letting you know I added a ‘Connect’ button on my GitHub page which will install ESPLink directly from the website.

https://aceindy.github.io/esp-link/

Note that I have re-compiled the firmware to host on ports 23 and 2000, which allows to use the newer myDPRemote app too (as it has port 2000 hardcoded).
In order to install the newer firmware, first install the firmware normally, then use the upgrade page on the web interface to install user2.bin (use the raw download button on the right)

hi, good evening i’ve followed the intructions for esphome. the device is online yet it says not connected.
I am using an esp32-wroom-32e board which receives the 5vGND etc.
when i did plug it in whils the furnace was on it went to say cool fire and turned off.

[aceindy]

I found the esphome not so stable, so I went back to ESP-Link.
Made a online installer to install it easily → https://aceindy.github.io/esp-link/

Either way, it should show some data on the logs…have you tried swapping TX/RX ?

Also, recommend to turn on debugging…

[DutchDeveloper]

Yes i’ve tried swapping RX and TX. i think my levelshifter i added didnt work. because the esp32 cant receive 5V directly.
i used now an ESP D1 mini pro and i get now information from the pallete stove in the mydpremote app.
on the esppage i see that Connected turns on and off every once in a while
i will try ESP-Link and see if this is more stable.

[DutchDeveloper]

unfornatly having issues with esplink through your espwebtool where my device is constantly boot looping, and i cant seem to download the latest version through the download link.
ill go try to use esphome and enable debuging
