Wemos D1 mini V4.0.0 supported? #111

So they have enough GPIOs available since you only need 3 for a basic Security+1.0/2.0 setup or 8 if you wanted to have the dry contact side of the board as well. Those pins are available GPIOs like the ones usually labeled with Where the problem might come in is whether that particular board is currently supported by ESPHome, or if there is a near enough equivalent that you could get by. You see, when you configure the firmware, you have to assign a board so that it will know a little something about the hardware that you are using, including the particular microcontroller and how much flash is available. This actually led to an issue with RATGDOs where the firmware was perceived to be too big for the available flash, which was considered less than reality because of the board that was chosen to be assigned. The problem was noticed when it was preventing people from updating, and the ultimate solution was a slight tweak to the board selection. These boards are running an ESP-8266EX microcontroller, which I assume would fall under the ESP8266 platform seeing as they do use the datasheet as a source near the bottom. However, a cursory search through the board list didn't seem to turn up these specific boards, which may mean that you will have to hunt through for one with the same general stats if you want to try it. You could look around to see if anyone has used these boards in general with ESPHome and what their configurations look like to see what board they assign. If they do work, then it should be possible to reconfigure the RATGDO firmware a little to use with these boards. |

Thank you for your reply, I am currently trying to make this work and I connected it like the schematic and installed 2.5x firmware. So I connected it using GPIO13(MOSI), SCL and SDA on the wemos d1 mini V4 and my garage door opener has these ports like the one on this picture (not my picture) I have connected the wires like in that picture, so red to 0, white to 2 and black to 3. What can I try to do now? Or should I just get a different esp? |

I think I would only have to change the code so that it uses gpio 5 for SCL and gpio 4 for SDA. That would probably fix it but I have no idea on how to do that or if that is even possible. |

It's actually surprisingly easy to modify ESPHome configs, but I'll admit that it's a little hard to work out without reading basically all of their documentation. In order to reassign the pins, you will need to take a look at the basic configuration files in this folder such as this one for the v2.5 with an ESP8266 D1 Mini. Which one you use depends as much on the protocol you need (Security+1.0 vs. 2.0 vs. dry contact) as the microcontroller that you are using. At the top of the files, you have the In here, you can reassign the pins being used for the TX, RX, obstruction sensors, etc. by simply changing the pin like so: or even replace the pins with nothing by assigning Since it looked like you can't use the BonusYou can also remove sensors that you aren't going to use to have fewer entities created in HA or de-clutter the web server. You just have to go through the base.yaml to find the particular sensor you don't want, then use something like the following to remove them: Just remember, you have to use the component's section header, then And in case you didn't already know:This process is based on compiling a custom firmware by creating a |

I have a wemos D1 mini V4.0.0 (The one with USB C)
I was wondering if this board is supported as I don't see the D pins on it but instead it has pins like 5, 4, 0, 2.
Are those pins just renamed and will it work or do I need an older version of the D1 mini?
