How to support Open/Close button

[rkotulan]

Hello,

My remote Telis 4 Modulis RTS5 Channel Pure Hand-Held Remote 1810765 has Open and Close button. I can send prog, Up (one step), Down (one step), My command.

But I do not know how to simulate Open (roll blind up) and Close (roll blind down).

Any ideas?

[Legion2]

With my remote the Up and Down commands, open/close the blinds. Maybe you need to send to commands to repoduce this behavior with your remote?

[rkotulan]

I can send commands repeatedly. But my remote control does it differently.

[Legion2]

Did you try other commands?

[rkotulan]

Yes, 0x1 to 0xF :)

[Legion2]

Without more information about the protocol your remote is using, I can't help you fixing the problem.

[rkotulan]

I understand, could you suggest to me some (easy) way (hw + sw) how to read data from my remote and decode it?

[Legion2]

I have all the information about the protocol from this website and https://github.com/Nickduino/Somfy_Remote.

[rkotulan]

Thanks, I will be back if I make some progress.

[Legion2]

maybe #16 is related to this,

[rkotulan]

Do you know what seed is in the frame? It looks like the seed isn't random but actually the button code: 0x88 DOWN, 0x85 STOP, 0x86 UP.

[Legion2]

No I don't understand that part

Hello,

using the tool rtl_433 and the dongle I could see the result below that explain: It looks like the seed isn't random but actually the button code: 0x88 DOWN, 0x85 STOP, 0x86 UP.

Hex. codes of my remote control.

UP - f0f0ff34cb4b2ccb334ad2b4d2d532d353 STOP - f0f0ff34cccb2d4b32cb53355354b352d28 DOWN - f0f0ff34b54b534b4ccd55335552b554d48

[rkotulan]

Thanks, what kind of remote do you have. I tried these codes yesterday but it did not work for me.

I am going to order the dongle. :)

[vaguiner7]

My remote is SCE-R1 Gunmetal.

Yes, didn't work for me too, I think that is related to the buildFrame, the frame is different from the regular Somfy products.

[rkotulan]

You were able to decode your hex codes by hand?

[vaguiner7]

No, I used the tool rtl_433 to see my codes.

[rkotulan]

@vaguiner7 The dongle came today. What command do you use for rtl_433?

[vaguiner7]

Great,

I just used filtering the protocol somfy_rts: rtl_433 -R 167.

I really recommend the tool Universal Radio Hacker (urh) that you can use with the same dongle.

[rkotulan]

@vaguiner7 Thank you so much.

Finally I was able to make it work.

My problem was that method sendCC1101Command(Command command, int repeat = 4) has default repeat = 4. I this case the motor make just one step. When I send just one command then the blinds go up :)

[Legion2]

@rkotulan would you like to add some documentation?

[rkotulan]

@Legion2 sure I will write something.

@rkotulan Could you maybe post your complete solution in here? I have a curtain which is using the same remote as you have and i'm trying to figure out how to controll that with my WemosD1. And i think i have to solve a similar problem as you, because with the UP/DOWN command i can't fully OPEN/CLOSE the curtain.

[rkotulan]

@Leviathan09 Here is my code for ESP Home:

#include "esphome.h"
#include <ELECHOUSE_CC1101_SRC_DRV.h>
#include <NVSRollingCodeStorage.h>
#include <SomfyRemote.h>

#define EMITTER_GPIO 2

#define CC1101_FREQUENCY 433.42

#define COVER_OPEN 1.0f
#define COVER_CLOSED 0.0f

#define TILT_OPEN 1.0f
#define TILT_CLOSED 0.0f

class SomfyESPCover : public Cover {
private:
  SomfyRemote *remote;
  NVSRollingCodeStorage *storage;

public:
  SomfyESPCover(const char *name, const char *key, uint32_t remoteCode)
      : Cover() {
    storage = new NVSRollingCodeStorage(name, key);
    remote = new SomfyRemote(EMITTER_GPIO, remoteCode, storage);
  }

  CoverTraits get_traits() override {
    auto traits = CoverTraits();
    traits.set_is_assumed_state(true);
    traits.set_supports_position(false);
    traits.set_supports_tilt(true);
    return traits;
  }

  void sendCC1101Command(Command command, int repeat = 1) {
    ELECHOUSE_cc1101.SetTx();
    remote->sendCommand(command, repeat);
    ELECHOUSE_cc1101.setSidle();
  }

  void control(const CoverCall &call) override {
    if (call.get_position().has_value()) {
      float pos = *call.get_position();

      if (pos == COVER_OPEN) {
        ESP_LOGI("somfy", "OPEN");
        sendCC1101Command(Command::Up);
      } else if (pos == COVER_CLOSED) {
        ESP_LOGI("somfy", "CLOSE");
        sendCC1101Command(Command::Down);
      } else {
        ESP_LOGI("somfy", "WAT");
      }

      this->position = pos;
      this->publish_state();
    }

    if (call.get_stop()) {
      ESP_LOGI("somfy", "STOP");
      sendCC1101Command(Command::My);
    }

    if(call.get_tilt().has_value()) {
      float tilt = *call.get_tilt();      
      ESP_LOGI("somfy", "tilt: %.1f",tilt );
      if(tilt == TILT_OPEN) {
        sendCC1101Command(Command::Up, 4);
      } else {
        sendCC1101Command(Command::Down, 4);
      }
    }
  }

  void program() {
    ESP_LOGI("somfy", "PROG");
    sendCC1101Command(Command::Prog);
  }
};

class SomfyESPRemote : public Component {
public:
  std::vector<esphome::cover::Cover *> covers;

  void setup() override {
    // need to set GPIO PIN 4 as OUTPUT, otherwise no commands will be sent
    pinMode(EMITTER_GPIO, OUTPUT);
    digitalWrite(EMITTER_GPIO, LOW);

    ELECHOUSE_cc1101.Init();
    ELECHOUSE_cc1101.setMHZ(CC1101_FREQUENCY);
  }

  void add_cover(const char *name, const char *key, uint32_t remoteCode) {
    auto cover = new SomfyESPCover(name, key, remoteCode);
    covers.push_back(cover);
  }
};

The key point is to change sendCC1101Command to send command just once. When you send Up = Open, Down = Close just once the cover will Open / Close.

I enabled also tilt support. If you do not need you can disable it traits.set_supports_tilt(false);

If you need more details let me know.

[rkotulan]

@Legion2 Documentation update For remote control Telis 4 Modulis RTS5 I recommend sending the command Up or Down just once. When the UP command is sent once, the blinds go up (Open).

sendCommand(Command::Up, 1);

When the DOWN command is sent once, the blinds go down (Close).

sendCommand(Command::Down, 1);

If you want to tilt the blinds, send the Up / Down command four times.

sendCommand(Command::Up, 4);

or

sendCommand(Command::Down, 4);

[Legion2]

@rkotulan can you create a PR, else I can update the readme.

@rkotulan Thanks, really appreciate this. Will check the code and try to understand it as i'm not that good at coding such stuff.

Edit: @rkotulan Ok, first problem...it seems your code is not for ArduinoIDE i guess? So how can i use it?

[rkotulan]

@Leviathan09 I use ESPHome + HomeAssistatnt.

How do you imagine you will control the curtain? With button connected to wemos? It should not be a problem to rewrite the code for Arduino.

Okay, then i will try to figure out how ESPHome works or will check if a can adjust it for ArduinoIDE (have the example from MakerMeiks Somfy_Remote) My plan is to use one of my dashboards from iobroker on a small tablet or my phone...and maybe also my Amazon Echo at least for full Open/Close

[rkotulan]

@Leviathan09 this might help https://github.com/DrozmotiX/ioBroker.esphome

[Leviathan09]

@rkotulan i tried it with ESPHome and HomeAssistant and was able to perform a compile process but it failed and i don't know why. As already mentiond i'm not really good and such "programming" stuff. Maybe you can help me.

@Leviathan09 could you post here file my_custom_component.h ?

@Leviathan09 could you post here file my_custom_component.h ?

@rkotulan it's just a copy of your code from above Didn't change anything Just to try it if i'm able to handle esphome

[rkotulan]

@Leviathan09 and how you YAML for ESPHome looks like?

[rkotulan]

@Leviathan09 One thing, I have different board then you. I have similar to this one https://www.aliexpress.com/item/1005003818247483.html

[Leviathan09]

hm, okay i think the board shouldn't be a problem

But as i don't really understand your stuff from above i think i have to wait for the weekend to take enough time But thank you for your help so far

[rkotulan]

@Leviathan09 For build board is not problem but this line

#define EMITTER_GPIO 2

could depend on the board, but I am not sure.

[rkotulan]

@Legion2 please update documentation

[filzek]

Great,

I just used filtering the protocol somfy_rts: rtl_433 -R 167.

I really recommend the tool Universal Radio Hacker (urh) that you can use with the same dongle.

@vaguiner7 did you make the Library to work with TUBE? As we try to use it the TUBE seens to have a 7 Digits Hex ID, so, whenever we set it 6 or 7 digits it doest work.

Can you give me a help to try to solve this?

Using a RFLINK to sniff the RF communication it shows it as RTS and the Remote Control ID as 265822A

Also if @Legion2 could take a look at this would be awesome!
