Hi everyone, I wanted to share my recent project with you all. I’ve always been passionate about gardening, but I’ve never been great at remembering to water my plants regularly. So, I decided to create a smart irrigation system that would automatically water my garden based on the weather conditions. Here’s how I did it.First, I started by gathering all the necessary components. I have a Zisternenpump with a HMIP-FSM16 switch, which I can control via my home automation system. I also have a Wundergrund weather station that measures temperature, humidity, and rainfall. Finally, I have a Gardena Micro-Drip irrigation system that I wanted to automate.I’ve been reading through the forums and found some great tips on how to set this up. I decided to use Home Assistant as my automation platform because of its flexibility and the wide range of integrations available. I started by setting up the HMIP-FSM16 switch to control the pump. This was straightforward using the Homematic IP integration in Home Assistant.Next, I integrated my Wundergrund weather station. This was a bit more involved, but I managed to find a custom integration that allows me to access the weather data directly within Home Assistant. I set up sensors for temperature, humidity, and rainfall, which are updated in real-time.The tricky part was setting up the automation rules. I wanted the system to water the garden only when it’s dry and not raining. I used the rainfall sensor to determine if it’s raining and the humidity sensor to check if the soil is dry. If both conditions are met, the pump turns on for a set amount of time. I also added a failsafe to ensure the pump doesn’t run for too long or during the night.After a few trials and adjustments, the system is now working perfectly! My garden is getting the right amount of water without any manual intervention. I’ve even shared my automation rules on the forums in case anyone else wants to try something similar.I’d love to hear if anyone else has tried something like this or has any tips for improving the system. Happy gardening!
