To piggy-back off of the ideas presented so far: I would like to be able to assign a particular flow sensor to specific zones. I have 2 valve boxes, each with 4 zones and their own main supply line. I would like to add a flow sensor to each supply line since a single flow sensor would not work. If I could assign zones to a sensor then a number of possibilities open up.
First, it can be determined if a flow sensor is working properly. If sensor 1 is assigned to zone 1 and no sensor data is received or sensor data from sensor 2 is received (assuming two sensors are installed) then an alert can be sent to the user letting them know the sensor is not functioning correctly or is not properly assigned.
Second, the flow data for each zone can be displayed and color coded to indicate where the data was derived from (e.g., red if no data received for a run [perhaps only in the calendar view], green if from the sensor, or blue if from the formula base estimate). Also, adding a bar graph view to each day of the calendar will give an over all picture of when the system was ran and how much water was used per zone per day. This is particularly useful to me since one of the zones is connected to a pond auto-fill valve. I may turn-on that zone for 30 minutes, but water will only flow if the float on the auto-fill value opens. The formula base estimate will not accurately estimate the water usage in this situation without a flow sensor.
Third, a flow rate or total volume limit can be set for each zone to provide warning or alerts if that limit is exceeded, plus an option to automatically shut-off [or a choice of actions, such as alert only, shut-off and alert, etc] that zone can be set. This is like those Life-Lock commercials: "Why only monitor if you can take action?"
Forth, if you can enter the cost of water in your area, then you can estimate costs and $$$ saved.
What is the current status of the flow sensor software. Looking at all of the forums it appears the flow sensor software is still in beta? Thanks.
