Efficient battery operated rain detection?
I am trying to find a solution for rain detection.
I have tried out the Fibaro Flood Sensor - both with external and default probes and by principle it works fine - only problem seems that the probes drain battery when placed in water.
Since I can´t control the rainfall, the probes will often be in water/wet for hours and hours resulkting in my battery draining within a few days. The amount of water seems to be indicative of how much battery is draining, which only seems natural in the sence of how much voltage is led throug the mass of water. alarm cancellation setting is set to 1 hour, but that doesn´t seem to affect the power drain of the probes.
So, after months of struggling with different workarounds, I have 2. questions...
1. Have anybody found a efficient way of using/fix the Fibaro Flood Sensor as rain detector running only on batteries and not draining a battery per week?
I thought about connecting the external probes to a plasticstring (fishing wire) and lead the water from a small bowl via the strings, but not shure it will work/help?
2. Anyone have other solutions/products which does the job efficiently running on batteries? I looked at the Oregon PCR800 Rain gauge, but I need detection, not only meassuring to control closing of windows, retracting of rollers etc,
