Unfortunately my wemos D1 inserted in HA which controls almost all of my burglar alarm is dead.
I have to replace it but I ask you if I can (and how) copy the yaml code present in HA to the new device. I’ve searched the forum but haven’t found any answers.
Thanks for your help.
You do know how to copy & paste?

Quote for nickout alternately click on the 3 points of the code you want to copy - Install - manual download - save the bin file and then flash it on the wemos
Or on the commandline
cp /config/esphome/oldcode.yaml /config/esphome/newcode.yaml
Thanks for the replies but I’m still confused. I’m trying your suggestion and I think you’re referring to this
the yaml file is downloaded but how do i convert this to bin file? Sorry if the request is trivial but I’m not practical in this.
Choose Install

Ok. I created the .bin but now the problem is another one. While connecting two new and immaculate wemos the ESPHome-Flasher-1.4.0 program does not detect any COM on the PC. I reinstalled the drivers, as described in the esphome faq but nothing.
All very sad 
Tomorrow I will continue to try, tomorrow will be a better day 
I solved the copy using with another pc.
thank you
