KCF Posted February 25 Share Posted February 25 I have a leak detector 3 and want to use it on my pool to detect when there is low water. It will be tied to the Yolink auto valve. I need to find a way to have a delay in the detector for a fixed amount of time before activating the valve. This is because water in the pool is not always still, and waves can cause the detector to trigger low, but then high, but then low, etc. I want it to wait for the low water condition to remain true for about 1 or 2 hours before taking action (ie, low water state is TRUE for 60 minutes). How can I do this? Link to comment
sjenkins Posted February 25 Share Posted February 25 Either in the YoLink app in the automation you can add the delays and/or you could write your ISY program to do the same. Link to comment
Panda88 Posted February 25 Share Posted February 25 (edited) I have been playing with this for a while. What I would suggest is to average - maybe make 10 measurements some time apart and then decide if a large percentage indicates water is low However, I found that the continuous on/off drains the battery quickly of the leak sensor (when close to needing to fill). What I ended up doing may be a little elaborate. I took a Yolink Siren (without siren - essentially a programmable power supply) and used that to enable the sensor of the water leak sensor (open or close the connection through the cable. Then when I need to make a measurement, I enable the sensor (power on siren) and get a reading (or multiple) from the leak sensor. After that I power the sensing (siren power supply) off again (so it will always read open / close when not in use - thus not sending status change to the HUB). It takes a transistor and a few resistors so it may not be for everyone. I run the above on a schedule so it only fills the pool at a certain time of day when needed.

glacier991 Posted February 26 Share Posted February 26 Panda88, your Nodeserver for Yolink is a fabulous gift. Thank you . Also, I am presently exploring the nuances of YoLink devices and possible "hacked" (not truly hacked) other uses. Your noting that the Siren module essentially is a programmable power output device is golden information. Keep those nuggets coming, please.... and again my gratitude. Chris Link to comment
