again thank you for help me
i am beginner , so you mean one node is not a repeater now, but it can be ? a sensor and a repeater ! is this correct ? but i am beginner so i want know this is easy or hard ? ( convert a node to sensor + repeater !? :)
about second problem , now i just test devices and they are in 1 meter with me :) (now without any wall) but some time disconnect between node and gateway . and dont any work Unless with unplug and plug in gateway or nodes !
i have test it once with vera edge (esp8266 gateway) and more once with comoticz (windows) ( serial gateway)
in vera is better and most time i have disconnect when unplug vera ( esp8266 is connect with usb to my vera ) after power on vera for 1 hours or more my gateway dont work ! also some time ( little sometime ) Accidentally disconnect gateways with node , so unplug and plug in again (gateway and nodes)
in "windows domoticz" is more happen . some time ( more time ) after send codes , i receive this error "Error sending switch command, check device/hardware !"
is this better i use a 10 nF for radio ? i think problem is related to radio !
