Current Transformers
What is the maximum current transformer can be used for smart-MAC D103? Let's say there is a transformer on the 1000A with secondary winding 1A, will it work correctly with the device?
Whether API is available (WI-FI) D-103-12 when disabling the external network?
If only external network home wifi is still available-would like to see D-103-12, and that no external network.
D105-how to connect more than one temperature sensor?
The documentation stated that the smart MAC D105 contact 4 allows to connect 5 temperature sensors type DS18x20 or one
temperature and humidity sensor DHT22
How to do it. As far as I can see on sensors-e.g. Sealed masterkitovskij temperature sensor DS18B20
- 1-wire interface
- Red wire U Pete.
- Black wire GND
- Yellow wire Data
but it is not clear where any wires, and what to do for example with second or third sensor.
MQTT: no traffic to server
I just configured the device.
I enabled mqtt server config wit username and password.
Unfortunately in mqtt logs I cannot see the username from the smart-mac but just:

1557525454: Sending CONNACK to 10x.xx.xxx (0, 5)
1557525454: Socket error on client , disconnecting.
