How to integrate into Home assistant ? There is also MQTT

Any option to calculate Line to Line voltage between the line with smart maic 3 phase meter ?
by equation or by hardware ? 
thanks

It would be very helpful for me to see which devices received which local IP from DHCP server, since I have more than 50 and some are in really inaccessible places. Long term solution is to change them to static IP, but this would help a lot.

Thanks

Hi,

Is it possible to share selected device with other user/users ? Or can I register one device in two accounts?
