  Lesson19 - add water level sensor for automation in home assistant
Posted by: admin - 04-27-2022, 02:36 AM - Forum: Home automation training courses - Replies (22)



1. Chose water level sensor:

a. output dry contact for OPEN/CLOSE singal.
b. output DC 0-5v analog voltage.

2. create a new automation:

water-level-control-output4-on (turn on relay)
-------------------------------------------
Trigger type: State
Entity: input-1
To: on


Actions:
Action type: Call service
Service: Switch:Switch: Turn on
+ Choose entity

water-level-control-output4-off (turn off relay)
------------------------------------------
Trigger type: State
Entity: input-1
To: off


Actions:
Action type: Call service
Service: Switch:Switch: Turn off
