Have this same issue and it makes me crazy... I use a step up converter DCDC 1.8V up to 3.3 input and output 3.3V. If solder from DCDC Out via 220uF direct soldered after stabilizer of HC501 direct on pcb and sometimes it will detect motion where no motion happens. I use two AA accu and i know that they have together 2,4V. Less voltage less current. But i try also with normal AA 3V then i have this issue not so often. But i have. It will much more if the voltage will more less.
OK, i misunderstood that. Sorry.
BTW you can create an arduino gw and plugin via USB. I must do this 'cause I'm using Zwave.me gateway parallel and with stretch i get an error with both over GPIO.
Why you don't use timer lib?
I do this via Pimatic and Raspberry Pi 3
I'm not sure whats happened... But i think its working now. I try to investigate why it works now! If i find the reason i will post here. Thanks for help.
Thanks but it seems not to work. My serial Gateway is working well. My repeater works DHT sends temp and humidity but it seems that repeat function does not work. I'm a little bit far away from gateway. A stay beside my repeater with arduino mini pro direct connected via programmer powered with USB voltage. But i didn't get any connection. If i go beside my gateway all is fine.

Thanks for any help
Thank you very much for this quick reply!
I read a thread with gw.XXX commands. That confused me. API say only #define MY_REPEATER_FEATURE.
Now it's more clear to me!
Hello together,
i try to understand how does it works. Did i need really only #define MY_REPEATER_FEATURE ???
Must i set some variables in loop or define more that i can use this as repeater?
DHT11 takes some time to read out data. Normally we do this over sleep. But in this time the repeater feature will be blocked. I read so many threads and posts here at mysensors that i get more and more confused.
What i understand at the moment, that i only need #define MY_REPEATER_FEATURE and loop does not contain any sleep. Is this right or not?
Greetings Wikibear
