HERMES ELECTRONIC WR3223 ventilation controller ESP32

[schmurgel (Marcus)]

Hello @mcweis,

Sorry for the long absence.

In the last update I added some commands for testing. (SP, Re, Rd and Es)
There is no sensor component connected to these 4. The “Failed” output is misleading because they didn’t fail, they just couldn’t process the data received from the WR3223 to publish them for HomeAssistant. (The received value is displayed at the end of the line ‘Data: xxx’).

All known commands can be found in wr3223_commands.h.
You can add them as standard commands that will be executed every cycle (the interval is at most 20 seconds or less).
Adding or deleting is possible in the commandPair array in wr3223_controller.h (from line 73). You need to adjust the cmdPairCount to the number of commands in the array on line 72 when changing the amount. This allows you to test all commands and the values ​​received by the WR3223.

Here are the explanations for the 4 commands:

// Zuluftsoll Temperatur auslesen/schreiben (nur bei PC Steuerung) 
    static constexpr const char *SP = "SP";

    // Zulufttemperatur Sollwert
    static constexpr const char *Re = "Re";

    // Raumsollwert 
    static constexpr const char *Rd = "Rd";

    // Schaltpunkt Sommer stopp lesen/schreiben 
    static constexpr const char *Es = "Es";

Best Regards

I found some interesting documents (not from Schwoerer, but about a WR3223):
PDF

Chapter 3.7: In summer operation, the device bypass flap opens depending on the operating status
Outdoor air and indoor temperature

Problem:
The sensor for detecting the room temperature is located in the
Control unit.

BUT: Chapter 2.3:
Alternatively, you can also connect an external sensor
possible in another room.

I think that it will be possible to control the bypass if we manage to add an external temperature sensor.

Hi,
that would be awesome.

Can’t we just forward a temperature sensor over the esp?

Edit: Your link is broken, I get an this page is not availible error

[schmurgel (Marcus)]

Thanks, I corrected the link.

That would theoretically be the easiest. But I wouldn’t know how. The actual control takes place within the WR3223. So far I haven’t seen a way in which the temperature information can be written. The sensors are currently connected directly to the WR3223 and the ESP reads out the various information via commands to the WR3223. (cmd T1 - T8).

It looks like the interior temperature is necessary in order to ‘automatically’ switch the heat pump and additional heater via the WR3223 in winter operation. The inside temperature information is also necessary so that the bypass is opened in summer operation.

According to this document, an alternative temperature sensor can be used. It also seems to be possible to open the bypass for testing purposes when the safety switch is pressed. Maybe that would be another approach.

There is a circuit diagram on page 32.

In my case, T2 is already connected to 9a/b. But 10a/b is free.

[schmurgel (Marcus)]

Here’s a little update:
Unfortunately, it does not seem to be possible to connect another (external) sensor with this version of the WR3223.

I think I’ll just add a relay to control the bypass directly.

@schmurgel

I think I’ll just add a relay to control the bypass directly.

Hello Schmurgel,
Have you summarized the files anywhere? I also want to control my WGT with HA.
Thank you very much in advance!

First of all, thank you for developing the solution! I hope that I can finally integrate my ventilation system into Home Assistant.

I have been trying for a few days to connect my WR3223 controller (Schwörer WRG 400 BP) to Home Assistant using the ESP solution. Unfortunately I still haven’t managed it, I always get this error message:

I am surprised that the error message doesn’t change regardless of whether I have connected the TTL port of the control unit or not. In any case, the “control unit” isn’t connected.

My previous troubleshooting consisted of:

• Used three different ESPs (BerryBase NMUC-ESP32, AZ-Delivery ESP32-WROOM-32 and AZ-Delivery ESP32S)

• Swapped the cables to the TTL port

• Tried various GPIO ports

• Flash ESP via WLAN and via web.esphome.io

I just don’t know how to proceed. What am I doing wrong or where could the error be?

[Ferris2339]

Does anyone have any idea what the problem could be or what the error “WRITE:33” refers to? I am grateful for any help.

Hi Stekolos,

Thanks for sharing how you could make it work. Unfortunately I am still facing the issue of my ESP32 not willing to connect to HA, even though it connects to Wifi and I can ping it.

This is the warning I am getting, sometimes it has a different content, but basically it shows as offline in HA.
OTA updates are feasible and the moment I change the YAML file back to the original content which it had when I set it up for first use from within HA, it hooks up to HA perfectly fine.

I have realized, that when I take out the “baud_rate: 0” command, that it seems to at least show some signs of life and I can read out the log file from the web appplication, but still it won’t show as online in HA.

I would appreciate any input from someone who faced the same issues.
My ESP is from AZ-Delivery (KitC V2 ESP32-WROOM-32)

Here is some part of the logging which I was able to do while it was hooked up to my PC using web.esphome.io (I cannot flash the ESP from within HA as I don’t use https to show the dashboard).
What I realize is, that is takes 10 boot loops before it actually connects to Wifi. Then, after about 5 minutes, the whole boot loop starts again.

Hi @FooFighter

I had the same problems.
Until then simply used this module.
Since then, it has been working wonderfully without break -off and the updates of Esphomas no longer make raven.
Important, the ESP module definitely connects outside of the actual housing so that the WLAN reception is not disturbed.
