How do i send the data from dht 11 to domoticz usin usb (no rf or esp)
domoticz has recocnized the arduino by com 5. But no data in Domoticz?
Dick

Is there a note about this topic
so only usb and no rf or esp only usb on arduino with domoticz.
my .*ino with dht11 is working
but how can i connect this to domoticz.
installing by mysensors in hardware gives a comport contact.
but Then??
Dick

I have the hope that after the version 2.2 some errors are fixed
. ci in library in 'Mysensors'
. mystools in library 'Mysensors'
Or are this errors my fault ?
