![]() ![]() In this small piece of code published on my github you will get the web gui as in the picture above. I will use the Arduino IDE (you install wemos boards, google "wemos d1 mini install arduino") as that is still the most used DIY environment but I recommend you try platformio (installation ) as that is a much more capable IDE and build environment. However in this article i want to show how easy it is to add something more standalone but still with some cool functionality that you can build upon. If anyone struggles with making such a sensor i can probably help with that. There are tons of information on the MySensors site. Use the Wemos as a gateway with attached devices and add it as a switch or a dimmer for the feeding. You don't need to add another radio like RFM69 or so. Connect to a home automation via for example MySensors that is compliant with all major controllers.Poseidon project which also includes water level and quality control and monitoring (standalone without connection or potential downtime of other automation).So if you have a raspberry PI or already a Web server up and running, that would be my choice I like that division of concern and that project can work also for you even without all water level and quality sensors. So the controller and "alarm" logic is in another piece of software, which in many cases you want to be your Home automation (like Homeassistant, Domoticz etc). the setup I'm using) then the microcontroller is just a slave that connects to WIFI, listens to the MQTT messages and acts if getting order to feed + amount. You can of course use an arduino or whatever you are most comfortable with especially if you use an external box. I've chosen to use the Wemos D1 mini (lite) as the microcontroller as it fits nicely in a small area and it has excellent Wi-Fi range. ![]() Here is a YouTube channel for the full Poseidon project and one video for the fishfeeder (sligthly different web gui, connected over MQTT etc)īefore we start to program, let's go through our options. The fishes loves the feeder too :)Įven if you can order the plastic parts printed, it for sure helps if you have a 3d printer capable of printing PETG or ABS.įor a full write-up on the other parts of my pond control see my github: Finally I've settled with the solution that works best and it's been up and running for 3 seasons without issues and this is what i want to share. It's very relaxing and the automation possibilities are huge (probably main reason for me :-))! I immediately started to build my first fishfeeder and since then there has been quite a few iterations. Almost 20 years ago when me and my wife moved to our house we thought that the included garden pond with a few KOI fishes wouldn't last very long. Even if it is designed for 3mm KOI pellets it will work for other types of similar pellets or grain for fishes and birds. This fish feeder is one of the parts in my garden pond control called Poseidon.
