Short question. Is it possible to use this evofw3 in Domoticz combined with a nanoCul? If yes is there some guide on how to do this?

Hi,

I'm using evfw3 on a DiY NanoCul and receiving communication from the evohome environment goes well.
I also tried to send commands but without result. Is sending of commands supported with evofw3?

Regards,
Ed.

Windows doesn’t care of course, but the arduino ide on linux can’t find arduino.h because it needs a capital A. Or at least it does on my Ubuntu 20.04 install of the latest version.

I receive the error messages below when I use a nanocul usb stick in Domoticz. There are several devices discovered and works as expected but was hoping the error messages can be eliminated.

I bought a nano CUL, but after loading this software nothing happens.

I suspect that the pinout of the device is different from the pinout that is currently supported.

The device I have is this one: https://www.smart-home-komponente.de/nano-cul/nano-cul-868-extern/
I guess - on inspection - that the cc1101 is connected to 3.3V, while there is only a board definition for a atmega328p w/ 5V.

I followed the instructions from the README, pointed the arduino UI to evofw3.ino and pushed 'Upload'. There were no errors in that step.

From here I expected the 'Serial Monitor' to show some output. nothing. I tried giving commands like !F, V, !V, etc but there never was any response from the Arduino.

Can anyone give me some pointers on how to proceed debugging?

Thanks,

Jacco

I can seem to edit or send a PR for a wiki page.

The header description on: seems wrong:
https://github.com/ghoti57/evofw3/wiki/Message-Body#message-body
The wiki states:

00 RQ
01 W
10 I
11 RP

However in the code:

Correct order according to the code:

00 RQ
01 I
10 W
11 RP

(I'm quite sure this is wrong in the Wiki, as I handcrafted a packetheader based on the wiki, and an I message was recieved as W by a real HGI80)

I'd be glad to submit a PR to the wiki, but can't figure out how.

Update: Same behaviour with the latest 0.7.0 firmware.

When I issue the 0x10E0 request targeted to a specific device to an Arduino Nano, running the evofw3 firmware (evofw3\uart 0.6.1), I get no response (even when retrying 10 times). To other devices I do get a response. However when I issue the exact same request via an HGI80 to that specific device I do get a response.

The request that fails to get a response is:

RQ --- 18:000730 10:014494 --:------ 10E0 001 00\r

When I monitor the request being sent by the evofw3 firmware using an HGI80 I see the following:

067 RQ --- 18:070150 10:014494 --:------ 10E0 001 00

When I issue the exact same request (so using 18:000730 as the source) and monitor the request on the device running the evofw3 firmware, I see:

095 RQ --- 18:009964 10:014494 --:------ 10E0 001 00

So the only difference seems to be the source address mapping.

When I issue the request via the HGI80, the response (directly after the first request) I get is:

067 RP --- 10:014494 18:009964 --:------ 10E0 038 000001C8810B0700FEFFFFFFFFFF140807E35238383230000000000000000000000000000000

Do you have any clue why there is no response when using the evofw3 firmware and an CC1101 while there is a response when using a n HGI80?

Hi,

I bought a NanoCUL a few months back to be able to control my Evohome from Domoticz.

Have been able to discover all valve, but I'm not able to set the controller mode (normal, economy, off, ...) or set points.

I do see Domoticz sending the command, but don't see any response to that:

000 W --- 18:003618 01:204708 --:------ 2E04 008 01FFFFFFFFFFFF00
000 W --- 18:003618 01:204708 --:------ 2E04 008 00FFFFFFFFFFFF00

Somebody I know has a real HGI80 and he sees the following when changing controller mode:

095 W --- 18:012786 01:072015 --:------ 2E04 008 01FFFFFFFFFFFF00
049 I --- 01:072015 --:------ 01:072015 2E04 008 01FFFFFFFFFFFF00
047 I --- 01:072015 01:072015 --:------ 2E04 008 01FFFFFFFFFFFF00
095 W --- 18:012786 01:072015 --:------ 2E04 008 00FFFFFFFFFFFF00
049 I --- 01:072015 --:------ 01:072015 2E04 008 00FFFFFFFFFFFF00
047 I --- 01:072015 01:072015 --:------ 2E04 008 00FFFFFFFFFFFF00

Not sure what the three digits at the beginning of each line represent, but I noticed that in my setup it's always 000 when the second column is showing 'W'.

I understood that TX should be working with the latest firmware, or am I wrong?

Please let me know if you need me to run any tests or in case you need more information.

Thanks,

Frank

Hi,

I have evofw3 running on a 5V ATMega328P. Every now and again (~24-48h) it's stopping emitting any packets and doesn't respond to commands, requiring a reset. I appreciate it may be just the board but on connecting it to my dev PC just now I ended up in a strange state where it wasn't emitting packets but still responded to !F (I'm using that to test comms) - and then spontaneously fixed itself.

Does this point to any specific issue? I appreciate it may be unrelated to the loss of comms I've been getting (when that happens it won't respond to !F)

thanks

!F

082 RQ --- 30:071715 01:067930 --:------ 10A0 001 00
074 RP --- 01:067930 30:071715 --:------ 10A0 006 001518000384

etc etc, then board stops emitting packets, but still responds to the !F command with weird numbers, before eventually spontaneously fixing itself:

!F

# !F F=700000

EDIT: this may be a power supply issue!

Hi all,

I seem to have an issue with evofw3 and my "german" nanoCUL. I flashed initially the latest version of evofw3 but it does not seem to work - the device "is" transmitting (i think) but no one ever responds back.

If I flash the calibrate branch, I can now talk to most devices - they all respond and quickly. Unfortunately, it's only the controller that does not want to respond back but only randomly to some commands. It doesn't even work for ping. But it all works fine for OTH and other devices.

Any suggestions as to what I can try next?

Thanks.

I've just tried to upgrade from 0.4.4 to 0.7.

It's compiled ok and uploaded to the board, but all I'm getting is the version number message, no packets are being decoded.

I have followed the instructions in the readme, selected atmega328P (SW UART). Any clues on what the issue might be?

Hi, im trying to check if my setup is working.
I was guessing to check if the autotune process could be run on my Pi.

i tried screen /dev/ttyUSB0 115200 as mentioned in this post:
#6 (comment)

But i doesnt work.
Any tips if this is possible to run on a RPI? If you need any info from me please let me know.
Im not the biggest expert on all of this but im eager to learn and fixed a lot of other things on the RPI.

Hi Pete

Are opentherm messages generally working on your uart branch? I have been running this branch for the last few days, but do not seem to be getting any messages with command 3220 (https://github.com/Evsdd/The-Evohome-Protocol/wiki/3220:-OpenTherm-Message). This was working previously using one of your evofw2 branches, and would come through very regularly.

The only OpenTherm message that seems to be coming through for me is the ticker (1FD4).

Thanks.

Hi,

I bought the NanoculV3 board linked to under Hardware UART here in the wiki, then followed the Arduino-IDE instructions to flash the firmware.

However I always get these errors in the Arduino IDE:

I played around with the settings for 'pinout', 'processor' and 'programmer', but the result is always the same.

Anybody has an idea how to fix this?
Thanks in advance.

Maybe more hardware related than evofw3, but posting here as I am not sure where else to ask:)

Picked up one of these:
https://www.amazon.de/-/en/gp/product/B07T3H8VF2/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1

Seems to be the correct radio, frequency and Firmware.
Received yesterday and installed using Arduino IDE (on MacOS) using the following settings:

GetBoard Info returns: atmega328p (SW UART)

So its set up like so:

Tools-> Board "atmega328p (SW UART)"
Tools-> Processor "atmega328p (5V, 16MHz)"
Tools-> Pinout "Nano"
Tools -> Host "115200"
Tools-> Port = "/dev/cu.usbserial-A50285BI"
Tools - Bootloader "Standard Bootloader"

Sketch -> Verify/Compile
Sketch-> Upload

Both complete with no error

In serial monitor of Arduino IDE there is no output
In terminal monitor there is no communication
Using "screen" command in linux there is no output

Any advice on how to see output form the board or to test if it is actually working?
How often do these devices fail? As Sketch->Upload did not complain, I assume that the board is working.

I just can't see any output (hence ultimate use with ramses_rf/ramses_cc/HA does not see any output.)

Any advice on how to get this responding?

Many thanks

@ghoti57 it would be useful to be able to deterministically discover the evofw3 dongle's device_id.

My use case include scenarios where users have (or potentially have) more than one gateway, so that I can work out which is which without them having to tell my code that things are so.

I note it would also be useful to have this data even whilst having the device in a read-only mode, so sending a dummy packet is not preferred (and I can't be absolutely sure the packet I'm seeing wasn't from another dongle).

The obvious solution would be a traceflag, or to include this data in the !V response.

Hi
I have the Ebyte E07 dev board with uart. The processor is an stm8, does anyone know how to port this code for an STM8?

Hi,

is it possible to use an ESP8266 or an ESP32 with an attached CC1101 instead of the Arduino?
It would require a rewrite of the code I guess ( watchdog, io, timing, ISR or others perhaps)
but would it be possible?

I am using nanoCUL (Arduino Nano V3.0 ATMEGA328P + C1101 868 MHz), but no messages are coming even using minicom

minicom -D /dev/ttyUSB0

nanoCUL is plugged to Raspberry Pi 4b.

For flasing fimware I used Arduino IDE, exported binary to Raspberry and successfully flashed using

avrdude -v -p atmega328p -c arduino -P /dev/ttyUSB0 -b 57600 -D -U flash:w:/home/pi/evofw3.ino.arduino_standard.hex:i

Can you help me with this issue?

I was wondering if the firmware was compatible with this module?

It's a board that sits on top of a RB Pi, compatible with 'culfw' firmware.

I don't really mind what license.

I quite like MIT license (https://choosealicense.com/licenses/mit/) - that what I generally now use, and what others Evo projects like https://github.com/zxdavb/ramses_rf use. It's simple and permissive.

(In the past I've used the Zlib/LibPNG licenses before https://en.wikipedia.org/wiki/Zlib_License but not so much recently. NOTICE: the Zlib license doesn't require copyright attribution for binary distribution, but the MIT does. BSD licenses have multiple versions which has really discouraged their use).

I don't mind sharing licenses like GPLv2 or GPLv3 at all. No problems with them either - and I use them on some code.

https://choosealicense.com is a good start.

If there are blockers to doing this, then let's discuss here...

I can't upload this to my standard Arduino UNO (ATMEGA328P). If I set my board option to atmega328P (SWUART) It fails to upload immediately saying #error no baud rate defined. If I set the board type to atmega32U4 (HW UART), it gets further, but comes up with: Connecting to programmer: .avrdude: butterfly_recv(): programmer is not responding. This error gets repeated multiple times. My programmer is set to AVRISP - although changing that makes no difference. Please - have you any ideas?

Description of setup:

Evohome controller, connected to Remeha Elga Ace heatpump with R8810A1018 (Opentherm module)
Firmware version: WiFi module: 02.00.17.00, Application module: 02.00.19.33

Home Assistant config:

ramses_cc:
  serial_port: 
    port_name: /dev/serial/by-id/usb-FTDI_FT232R_USB_UART_A50285BI-if00-port0
    baudrate: 57600  #  default: 115200
  packet_log: 
    file_name: packet.log
    rotate_backups: 30

Nanocul from this supplier: https://schlauhaus.biz/en/product/nanocul-868/
Firmware: 0.7.1

Problem

After setup of the nanocul and software, all the sensors and entities became visible in Home Assistant. However, the heatpump started showing strange behaviour. Even though there is a heat demand from the Evohome to the heatpump, and output/return watertemp are below set point, every 6-10 minutes the heatpump stops heating for about 2 minutes. After this, the heatpump turns back on. The display on the heatpump doesn't show anything abnormal or error codes.

As soon as I disabled the ramses_cc plugin in Home Assistant, the heatpump started operating normally again. This can be seen in the energy diagram as attached. There was constant heatdemand most of the time between 11.35 and 13.50, but the heatpump was switching on and off. The peak around 13.40 was caused by setting the Evohome to 25 degrees to force a very high setpoint, but here the heatpump also stopped way before the setpoint was reached.

I disabled the plugin at 13.50. The Evohome send heat demand between 13.50 - 14.15 and 14.40 - 15.08. Between these timestamps, there is clear correlation between heat demand and power usage. Between 14.56 and 15.08 there was heat demand, but the heatpump reached it's setpoint. Therefore only the circulation pump was active which causes the lower power usage.

Outdoor temperature is between 10-15 degrees celcius, so defreeze cycles are not relevant.

It seems like the nanocul is interfering the messages between the Evohome and heatpump (connected through R8810A1018) Could this be caused by active probing?

Can you please tell me the pinning between ATMEGA328P (standard UNO) and the CC1101. I don't fully understand atm328_pins.h which I presume sets this. Thanks

Appreciate your responses to earlier issues, things now seem to be working pretty well for me.
