here is photo my usb gateway with STM32 power
it's a big difference with arduino nano

and that's a TV box turn into a mini pc more powerful than raspberry pi 3
and I installed linux with domoticez and imperihome EMMC Flash is fluid and fast
and toutsca works well

8 x CPU: Amlogic S912 Octa core ARM Cortex-A53 CPU jusqu'à 2GHz (DVFS)
GPU: 750MHz + ARM Mali-820MP3 GPU Processeur
RAM: 3Go DDR3
ROM: 32Go EMMC Flash
Système d'exploitation: Android 6.0
Ethernet: 100M/1000M
WIFI: 2.4GHZ / 5.8GHZ 802.11a / b / g / n / Ac
Bluetooth: BT4.1

@mfalkvidd good job

@dzjr
thank you for your reply
at least 10 children in node and 30 nodes
@dzjr

thank you for your reply
at least 10 children in node and 30 nodes

and it can have blockages if there are sensors that function or even time
thanks

Hi,
in a node how many children can put rs-485
thanks good work

@mfalkvidd good job

hi
I have this error
'class SensorMQ' has no member named 'setCurveScalingFactor'

thanks for the work you did
i add the motion sensor and light level sensor its not working well
you can help me thank you

in domoticz he sends his state of light
it is he and turn on or off

thank you for your response
light with classic toggle switch
and i have add pir sensor
for what I ask to correct
  I have to thank you
