[solved]Homeduino not running on Arduino UNO

---

Hi,

I was successfully runing a homeduino on a Nano (connected to a raspberry3) for couple of weeks, but was expirincing some lags when turning lights on/off.

So I wanted to try running homeduino on a Arduino UNO.
I followed the script that worked for the Nano -of course I changed the Makefile-

The flashing did work, via Serialmonitor I can read out “ready”.

I changed the port in the homeduino plugin to the correct dev/ttyXXX , and restarted several times.
BUT it doesnt work… The switching requests always “timeout”

I´m just stuck at the moment …

did you reset the uno after flash? power down ?
uno is working fine, mega too.
check the wiring, maybe there’s a mistake?

I powered down the UNO. Just by pulling the cable.
Should i reset it with the button as well ?

The wiring is just like in the instructions. Reciever on D4 and Transmitter on D2. ( I took these Pins out of this instructions which is for NANO. Bit it should be just fine right ?

Also make sure there is no other process or pimatic plugin trying to claim dev/ttyXXX at the same time. I had this problem a while ago which is nasty as you won’t get an error message but pimatic-homeduino will run into a timout after 5 minutes. In my case it was pimatic-johnny-five with a bad arduino board configuration (claiming the same device) causing the issue.

Yes, thought about that as well… I had mysensors running as well but already deinstalled and rebooted. But maybe I´ll start from scratch tonight.
I simply replaced the NANO to the UNO and changed the dev/ttyXXX in the config.
Maybe that caused Problems.

did the ttyUSBx change at all?
maybe you can use /dev/serial/by-path or by-id instead in the homeduino config?

Thanks for all the support.

I started fresh from scratch and now it works.
I declared both devices in the configuration by “/dev/serial/by-id” and now both Homeduino and mysensors work like a charm.

Have a nice evening everybody

nice to hear!
