Hello,
May I have two questions?
1, is there a way to add a 1602 LCD to the system to show e.g. date and time, last watering time, currently active relay, temperature and humidity, etc?
2, can I attach my Hunter rain sensor somehow to skip watering in case of recent rain?
Thanks in advance!
After double check the configuration, there was an overlapping of the PIN number. The same PIN 21 was used for interrupt and servo:

I am living in Germany on Berlin time.
Hello Angelo, I've replaced my sensor with a switch, reduced the query time to 2 mins and the watering plan is still working. The sensor is showing 100%. It reads that and is outputing that data on the monitor(actual hardware monitor) I have hooked up (Normalized reading). In settings I can override the pre-emptive blocking but as far as I am concerned that is the better behaviour. For me as a court keeper at the tennis club being able to test the fields (watering sections) at all times would be advantageous. Blocking the plan however should work because anyone seeing sprinklers working in the rain will suggest I am wasting water. I've tested the sensor again and it does disconnect when wet.
I've just tried Teamviewer on this old Fedora notebook and it is not currently working. I could take control of my desktop at any time to give you access to my system. How can I help you help me?
Well, the actuator test will not override the pre-emptive blocking, so if you try to start actuator from the setting page you will get the status as "Blocked". This will be an easy way to test the blocking status.
I understand the wording is a little confusing, this is because I tried to make more general purpose as with interrupt it is possible to do many things.
Please ensure the interrupt pin is not used for other hardware, you can check it in the "hardwaresetting" page.
Below my setting in the HWsetting page
This is the setting that I used in interrupt page:
To be sure the hardware is connected properly, check the "realtime" reading of the RainSensor:
When circuit closed should be zero, the pin is set to ground. When open should be a value >0.
Let me know
I've entered 60 as the "Max Time between interrupts". The wording here is just a little difficult to understand for me. The distinction between events, interval and sequence are a little confusing. Just my thoughts.
Hi, 116a is installed and Wifi is setup. Will the Actuators test override the pre-emptive blocking? If so then I will have to test in automatic mode, correct?
Hi, to reach the system you should just type the IP address and add the port number. In your case:
192.168.0.157:5172
Note that the port should be added using the column character.
Anyway if you want an easy way to connect to the system always with the same IP address without configuration on the router, you need to go the "network" page click the "advanced Setting" and change the default IP address to "192.168.0.172". In this way the system will always try to get from the router the this IP address. In your case you have to change the IP address because the subnet is 192.168.0 (the system default is 192.168.1).
Wrote something about it in another post:

Hope this help!
Look forward to fix the other part with the rain sensor.
Hi Angelo, my hydrosys4 is seen as a connected device but I was not able to login to the 113c version. Time to update.
Hi Angelo, after writing my post above I did find an entry error in the interrupt setting. The time was set for 5s instead of 15min. I changed that and this morning the Rainsensor readings are showing up. The rainsensor is still indicating wet and the actuators are just now switching through the watering plan?. After breakfast I will again attempt to connect to my router. I have managed this with my router showing the connection to hydrosys4. I was not however able to gain access to the web page. After I have attempted this again I will update to the new software and try again. The download I am experimenting with is "hydrosys4-113c(2020-03-19).img"
Hi Kevin,
Please make testing with latest SW release 1.16a, I've made some changes in the interrupt algorithm.
Quick comments for the release 1.16a:
1) The connections seems to be OK, as you see the 100% and 0% in the "real time". This value indicates the pin going to 3.3v when circuit is open or to 0v when circuit is closed.
2) The RainInterrupt will be visible on the chart only when the interrupt occurs or when the Blocking period is renewed or finished. If you set more than one Irrigation line on the same interrupt then you will get multiple of 100. (if the scale is set to 100)
3) The blocking period should be set to a number of minutes which is >0 (maybe 20min as example)
4) Wet Open / Dry closed, this is same as I have in my setup.
Can you post a screenshot of your configuration on the interrupt page? Let's take one irrigation line as reference.
Just for curiosity, is it not connected due to unavailability of the network or because there is an issue? In such case we can address also this point.
I'm happy that you are testing this feature, let me know.
Angelo
Hello, I am also using the Hunter "Rain Click" sensor. I want to use it to control watering of 5 to 6 tennis courts. I have followed the video when installing the sensor. In "Settings" I can read the "Real time data". This does reflect or show what I believe are correct values. When wet the sensor reacts immediately and shows a value of 100 %. When it dries out, 0%. My first test this morning was however a failure. In the wet state the watering plan ran as normal. Pre-emptive Blocking has not functioned with the settings I followed from the video. Has anyone got this configured so it works?
I have yet to install a system clock so I can test in real time since I have not been able to login through my router so far. Another interesting point is that although I can test the sensor in real time my sensor chart has only an entry for "TimeTrigger" in it. The "Home" page also shows the Rainsensor but it's value remains at 0% with a min and max of also "0". I don't know if the shown values on the homepage are significant although the home page does show the on times for water correctly.
As I was following the video instructions I did wonder if "second edge and level" would be correct? The Hunter sensor does switch to open when wet and closed while dry. Being able to see on a chart how long it takes to dry out would help to set the vents on the sensor for appropriate drying times.
Namaste, Kevin Tough
Just made a video about the Rain Sensor:

I would be more than happy to read that post :)
Hi, I purchased and tested a rain sensor which is of switch ON/OFF type. This type of sensors are made with a material that expands with water, this expansion trigger the activation of a mechanical switch. Until the material is wet, the switch is activated, so this state can persist for several days until the material dries.
The switch is normally closed, when the rain is detected the switch opens.
This type of sensor is made to be put directly in series with the valves, it can controls several valves at same time if it is connected between the valves and the common.
For this easy type of connection, I do not see direct involvement of the hydrosys4 system.
Anyway in case we want to monitor the activity of the sensor and we want to flexibly associate the valves to be controlled by the rain sensor, it is possible to connect the sensor switch to the interrupt pin of the raspberry.
I plan to write a post on this topic.
Hi! I am also interested in connecting a rain sensor. Can you please describe how to connect and what to set up in the software in order to stop watering in case of rain detected? Thanks! I am a big fan of hydrosys :)
Thank you for the quick answer! May I ask why is it impossible? There are not enough GPIO's left? There is no way to reduce the number of irrigation lines to 8 which would free up GPIO's and implement the LCD feature? (Sorry for the lot of questions, I'm a bit new to RPi)
I guess you are right, it seems that it's only an on/off sensor. Can you publish a schematics how to connect the buttons and the sensor as an interrupt?
Hello,
For question 1, I see no way to connect the display
For question 2, it seems that the Hunter rain sensor is just on/off sensor. In this case we can set the system to listen for interrupts. When the sensor will close, then the system will understand there is rain and stop irrigation for a set number oh hours. I think this is quite feasible.
Can you briefly describe the specs of the sensor?
