@yveaux said in Ikea Molgan Hack:
@magpern the instructions on openhardware.io state that the Molgan must be battery powered while programming:
Well, then I can confirm that you don't have to power the Molgan from batteries just for programming. Burning the bootloader works fine with just power from the ISP port and programming it through FTDI works fine if power comes from the FTDI.
What I found wierd is that the atmega328 had power, the radio had power, it wrote debug messages to the FTDI - when powered through the FTDI, it send radio messages etc, but it just did not receive messages.
Messages where not received until I supplied power to the + / - pads (battery pads).
I did read the instructions on openhardware.io, but I didn't follow then to the t.

Can I have the pcb in the first shed also working as an extender, so the second pcb will be able to send out topics to the gateway as well? What to add to my code to achieve that?
you must program it to be a repeater. Of course it will need to have radio on all the time, so it cannot be battery-powered.
