We have water motors at every house to pump the water to our Rooftop Water tanks from where it is distributed within the house. 

1. I have 4 Sensors in my water tank placed at different levels in the Water tank ( At 0%, 50%, 100% and Water Pump Intake Pipe)
2. I have connected above sensors to my Raspberry Pi to GPIO pins so they trigger the following named switches in Domoticz - 'Low', 'Med', 'High' and 
'Waterin' respectively.
3. I want the water Motor to start daily from 6 AM to 7 AM and 6 PM to 7 PM only when Water in tank is Less than 100 and 50% and 0% (so Motor will only start when Water % is less than 100% in the tank) and when it's the time for the Public Water Supply times (ie. from 6-7 AM and 6-7 PM)
4. Finally in the scenario when No water is being pumped during above conditions (no water in the Public Supply but still Daily water time of 6-7 AM and PM) - the motor should stop and check periodically and start / Stop motor.

If I understood your setup and requirements correctly the dzVents code below should work for you.

Code: Select all

-- waterTank.lua   for dzVents >= 2.4
