Hi there,
I just started using Home Assistant and am quite happy with the first results and how easy the first steps were!
I started reading Data via ModbusTCP from a 3-Phase AC meter as a sensor in the configuration file. The number (power in Watt) is an INT16 with values from -32668 to 32668. Reading and displaying works, though I’d like to visualize the data better. It now shows a negative value ‘X’ as ‘65536 - X’
I there a trick how do some simple math in the configuration.yaml file so the shown data is according to the measured values? Unfortunately I didn’t find anything on this topic yet.
This is how it looks like now;
Modbus
modbus:
type: tcp
host: 192.168.xxx.x
port: 502
Modbus sensor
sensor:
- platform: modbus
registers:
- name: L1
unit_of_measurement: W
slave: 30
register: 2600- name: L2
unit_of_measurement: W
slave: 30
register: 2601- name: L3
unit_of_measurement: W
slave: 30
register: 2602
It would be great if somethin like this would be possible before displaying:
Y = X
If X > 32668
X = - ( 65536 - Y )
return X
Thanks in advance!
