This page describes how the module of a Wemos D1 mini and ESP8266 is wired to the radio module and is flashed with the latest Firmware.<br/>
Further information will help you to communicate to the compatible inverters.
You find the full [User_Manual here](User_Manual.md)

## Things needed
In order to build your own Ahoy DTU, you will need some things.<br/>
This list is not closing as the Maker Community offers more Boards than we could cover in this Readme.<br/><br/>
We suggest to use a WEMOS D1 mini Board as well as a NRF24L01+ Breakout Board.<br/>
Make sure it has the "+" in its name as we depend on some features provided with the plus-variant.<br/>
Any other ESP8266 Board with at least 4MBytes of ROM could work as well, depending on your skills.

To also run our sister project OpenDTU and be upwards compatible for the future we would recommend to spend some more money on an ESP32 board which has two CPU cores and a NRF24L01+ module with external antenna.

Once your Hardware is ready to run, you need to flash the Ahoy DTU Firmware to your Board.
You can either build your own using your own configuration or use one or our pre-compiled generic builds.

8. the ESP will start as access point (AP) if there is no network config stored in its eeprom
9. connect to the AP, you will be forwarded to the setup page
9. connect to the AP (password: `esp_8266`), you will be forwarded to the setup page
10. configure your WiFi settings, save, repower
11. check your router or serial console for the IP address of the module. You can try ping the configured device name as well.
Once your Ahoy DTU is running, you can use the Over The Air (OTA) capabilities to update your firmware.
! ATTENTION: If you update from a very low version to the newest, please make sure to wipe all flash data!
## Connect to your Ahoy DTU
When everything is wired up and the firmware is flashed, it is time to connect to your Ahoy DTU.
When everything is wired up and the firmware is flashed, it is time to connect to your Ahoy DTU.
#### Your Ahoy DTU is very verbose using the Serial Console
When connected to your computer, you can open a Serial Console to obtain additional information.<br/>
This might be useful in case of any troubles that might occur as well as to simply<br/>
obtain information about the converted values which were read out of the inverter(s).
#### Connect to the Ahoy DTU Webinterface using your Browser
After you have sucessfully flashed and powered your Ahoy DTU, you can access it via your Browser.<br/>
If your Ahoy DTU was able to log into the configured WiFi Network, it will try to obtain an IP-Address<br/>
from your local DHCP Server (in most cases thats your Router).<br/><br/>
In case it could not connect to your configured Network, it will provide its own WiFi Network that you can<br/>
connect to for furter configuration.<br/>
The WiFi SSID *(the WiFi Name)* and Passwort is configured in the config.h and defaults to the SSID "AHOY-DTU" with the Passwort "esp_8266".<br/>
The WiFi SSID *(the WiFi Name)* and Passwort is configured in the config.h and defaults to the SSID "`AHOY-DTU`" with the Passwort "`esp_8266`".<br/>
The Ahoy DTU will keep that Network open for a certain amount of time (also configurable in the config.h and defaults to 60secs).<br/>
If nothing connects to it and that time runs up, it will retry to connect to the configured network an so on.<br/>
<br/>
If connected to your local Network, you just have to find out the used IP Address. In most cases your Router will give you a hint.<br/>
If you connect to the WiFi the Ahoy DTU opens in case it could not connect to any other Network, the IP-Address of your Ahoy DTU is 192.168.1.1.<br/>
If connected to your local Network, you just have to find out the used IP Address or try the default name [http://ahoy-dtu/](http://ahoy-dtu/). In most cases your Router will give you a hint.<br/>
If you connect to the WiFi the Ahoy DTU opens in case it could not connect to any other Network, the IP-Address of your Ahoy DTU is [http://192.168.1.1/](http://192.168.1.1/).<br/>

## MQTT command to set the DTU without webinterface
Disclaimer: these are collected examples from https://www.mikrocontroller.net/topic/525778 (Page 12)
in manual.yaml you will find the setup for manual configuration, adapt your name (Terrasse) and the topic (inverter) to your needs and place it into configuration.yaml
in autodiscovery.yaml you will find the setup for automatic discovery of the inverter
Note: the config might need adaption to your system (mqtt, homeassistant etc)
