[Question] Pin-naming on ESP8266

[CrimsonAC]

Hello and first of all thank you for this project. I am right now trying to get it running, but at the moment to no avail.

I tried a Raspberry Pi B+ with the code from Nickduino and that works, so the prepared Transmitter with the swapped 433.42MHz crystal is operating correctly.

So i guess i just have a problem sorting out what Pin on the ESP8266 i should use. In the config.h is PORT_TX set to 5. But where on the ESP is that? I found a translation table that says Arduino Pin 5 is WeMos D1 mini Port D1 for example. I tried (among others) to use PORT_TX 4 or alternativley the constant D2, but i get no reaction on my shutters.

Thanks in advance.

So exctied to see your post.

I am using NODE MCU V3 - ESP8266 and i cant work this out either !

Update: After seeing your comment about the D1 pin on the wemos i tried it on my ESP and it worked

[CrimsonAC]

Hm, good to hear that it now works for you. But it makes me wonder why it doesn't work for me. I use a D1 mini Board, which is a NodeMCU based on a ESP8266-12F chip as well.

If i got the documentation correctly, i could use either D1 or 5 in Arduino to address the Pin named D1 on the board. The NodeMCU-numbering for the D1 Pin should be just 1. But that also does not work. Maybe the problem is somewhat else.

Maybe you could share a picture or a drawing on how you connected everything up.

[AlexHello]

Yes of course will post later. Did you checkout the photos from the project might this help if your D1 mini is the same ...

Yeah i've seen the pics in that repo. Maybe i have some time tomorrow and give it another shot.

[AlexHello]

Good luck. This is my setup on nodemcu v3 esp.

Also I've ordered a wemos d1 from China and once it arrives will give it a shot aswell but delivery will likely take a month.

Thanks for the photos. I just took another D1 mini, resoldered everything, flashed the sketch (with the constant "D4" as pin to use) and it works. I don't know if the first D1 was damaged somehow or i messed up soldering, but now it works.

Thanks again and thanks to Roy Oltmans for the code.

[AlexHello]

YAY !!! So happy. Im still struggling to expand the code to control more than one blind if you work this out let me know :)

Sure!

You just have to modify that "Remote vector" in the config.h There is already one remote configured: std::vector<REMOTE> const remotes = {{0x184623, "home/nodemcu/somfy/[DEVICE ID YOU USE]", 1, 0} };

Mine for example looks like this: std::vector const remotes = {{0x123456, "edomi/status/internal/1108", 1, 0 } ,{0x971547, "edomi/status/internal/1109", 1, 4 } ,{0x346124, "edomi/status/internal/1110", 1, 8 } ,{0x187542, "edomi/status/internal/1111", 1, 12 } ,{0x244412, "edomi/status/internal/1112", 1, 16 } };

I hope this helps.

[AlexHello]

Thanks it does. For the above example what are your status topics ( line 35-37 in the sample code ).

Do they need need to be duplicated for each remote ?

[CrimsonAC]

Cool. I have not really used the status topics so far. The "state" for example delivers an 'open' as response, no matter what remote i used last. So i guess it's universal.

[AlexHello]

Thanks that word a dream for getting them controlled. I have these setup in home asstant now but i think there needs to be a state / availablity topic. All my blinds in HASS control the correct blind but controlling one updates the states for all the others at the same time.
