Tank Level control & Drain valve closure

[beno_283]

Ben,

I have a question.
First, the plugin page will have some fields for user input:

• maximum tank capacity in centimeters
  
• Sensor offset (distance of sensor above maximum)
  
• minimum water level which will trigger stopping outflow from the tank.
  

click to enlarge.

The water level will be calculated by subtracting (measured distance + sensor offset) from the maximum capacity in cm.
When the water level reaches the minimum, do you want SIP to suspend / stop all programs?
or
Do you want SIP to switch to an alternate water supply?
That would involve using 2 master valves, one for the tank and one for the other water supply. SIP already has a master valve option for a single station to be master. We could probably have the plugin select a second station for the alternate supply. The plugin could re-assign which station is the master without making any changes to the core program.

If the tank is filled by rain, you would probably want to have the plugin switch back to using water from the tank. That would require an additional input field for a water level that would trigger the switch back to using the tank for irrigation.

Let me know.

Hi Dan,

Sorry for the long delay in replying, this year has just taken off! The Maximum capacity is 180cm, the measured distance from the sensor to the minimum is 160cm minimum level is 10cm. In this instance there is no backup water supply, just the rain. Could we make this all into a plugin where the maximum capacity, offset to the sensor and backup master valve allocation? 


Cheers
