IMPORTANT! Its no longer an Alpha version! You can now use Rainmaker in the release version of the Arduino IDE!
ESP Rainmaker is available in the Arduino IDE! So now we can control our IOT devices from phone or tablet using the free apps available on IOS or Android.
Yes - ESP Rainmaker was released beck in 2020 but the precompiled version is now availalbe for the Arduino IDE and that means that many more people will be able to access the amazing functionality it brings.
With phone apps for both Android and IOS, Rainmaker has a easy to configure library that allows, Over the Air updates (OTA) as well as remote control of devices, and voice control via Google Home or Alexa. It also has a REST API and a Python API. And best of all, its free!
In this video, we look at how to install and run an example app - don't worry, we'll bring you more real-world IOT examples in the near future!

very entising to try out but I need to finish some 'projects' first. The 'switch' and 'fan' are toggled pins on the ESP32 like you show with the LED in the start of the video ?

@Magic-Smoke 3 жыл бұрын

Hey Maico - I have so many projects to finish but this was pretty exciting for me. Really Rainmaker is just mapping the name of a device to each pin so with one ESP32 you can control many devices. But you can also read information - for example, a battery voltage. The you have the information so you can decide whether you should turn a device on or off. Of course, you can also use a port expander like the MCP 23017 and run dozens of devices :)

Thanks for the video, I'm trying to find a solution to monitor the soil moisture and water levels and run a pump for a project I'm working on. I'm wondering what the limitations to rainmaker is? Could I have 3-4 projects for free? Can I share my "app" with someone else? What's the data retention for it? I'm not seeing many things on rainmaker but from what I do see it looks like a good alternative to the arduino iot cloud or blynk

@Magic-Smoke Жыл бұрын

@tadcrazio I'm glad you enjoyed the video. If you take a look at the concepts in this video: kzfaq.info/get/bejne/isdpl9p1qZ-rqXU.html then you can definitely achieve what you want to quite easily. For example, create a Rainmaker Bridge for all the devices in your project and use a tool like Node Red to read the MQTT messages and store them in a database like Influx DB. You might then display the data on a nice dashboard in Grafana? You could also then do some pump automations in Node Red and feed back the pump status in Rainmaker so you can view what is going on from anywhere at a glance

Actually, when I uploaded the RMakerSwitch sample code through Arduino, some messages popped up saying that “Failed to allocate memory”, “Device handle cannot be NULL” and “ESP Rainmaker not initialised”. I am not sure what was wrong about my board. 😢 Do you know what was the reason behind?
