It looks like I have a similar rain sensor. I think the sensitivity switch just adjusts the point at which it triggers. I never get a "Dry" situation - it just hovers around 30-35%. So I've set Dry Threshold to 70% and Wet Threshold to 0% - effectively disabling it.

My project box also leaks - had to seal the joints with sticky tape. Will get something better or I might drill some drainage holes.

The lines I amended are:

float avg_delta_celsius = 15.5; //WMcS Edit - was 21.5

avg_delta_celsius = ((avg_delta_celsius*79.0) + delta_celsius)/80.0; // WMcS Edit - Reduce averaging period

Hope this helps.

Hi Peter

A quick update. I have a 3D printer, so I printed off a series of smaller and smaller aperture reducers (for want if a better name) until I got some sky temperature readings that I thought were reasonable. So, I’m testing that at the moment! My rain sensor module, I think, just indicates rain or no rain so that has been impossible to properly calibrate in the ascom driver. So I’ve disabled the rain sensor. I’ve also tweaked the Arduino code so that the unit starts off as Unsafe and then changes to Safe if the avg temperature difference warrants it.   The original code started at an avg diff of 21.5 degrees which I felt was a bit high. This meant the driver immediately indicated Safe, even with clouds, then changed to Unsafe a short time later. I prefer to start Unsafe. 
If you want any of the 3D printed gizmos, let me know. If you have any suggestions on the my rain sensor issue, let me know. 
Cheers

Is this more like it?

Neat! Is this simply to restrict the field of view? 

Testing it now. This is my settings screen. To get it to trigger rain with a small drop of water, I need these settings. But my sky temperatures don’t look correct. Do they?

I think the problem is down to my soldering skills (or lack). I tried multiple times to solder the pins to the IR sensor and I probably caused heat damage. I have ordered another one so I’m not giving up just yet.😊

I can’t remember the IR readings I was getting but I will make a point of recording them if I get it going again. It’s all good fun.

I spoke too soon. After about an hour outside it threw up an error and I can’t get it to work now. I think I might just invest in a commercial product. 

It’s not pretty but it all seems to be working. I’ll put it in a plastic tub and test for a couple of days before committing to a project box. 
Thanks for your help 👍

Hi Peter

My temperature sensor arrived today and I’ve rigged it up on a breadboard. I’m not sure if I’ve got the resistor in the correct position. I think it’s called a pull-up resistor and I only have a 5k1 Ohms one rather than the 4k7 Ohms one specified in the build doc. Do you think this looks correct? 
Thanks

Hi Peter

Great. That’s really good to know. I’ll let you know as soon as I get a build done. 
How is it been working for you?  I’ve built a simple rain sensor and that works ok. It would be good to get the cloud detection working.
