- | cd <arduino directory>/ | + | now we can finally add the enocean receiver |
- | git clone https:// | + | |
- | for my development machine to receive those messages i need to open a socket with '' | + | next we need the [[http:// |

+ | I should have done this right after implementing the WiFiManager as one could also use mqtt for debugging messages rather than trying to use AsyncPrinter which did not work in conjunction with mqtt and was painful to figure out in the first place. so now this contains a solution for debugging via mqtt. | ||

+ | download the [[https:// | ||
