OpenSprinkler Integration for Home Assistant

In Apple Home through HomeKit Bridge

What HomeKit Bridge makes of each kind of entity this integration creates, read from its source code. A device only gets the ones that apply to it.

Entity	Shows up as	Note
`switch`	Switch or outlet
`binary_sensor`	Sensor (motion, contact, leak, smoke…)
`sensor`	Sensor (temperature, humidity, air quality…)
`select`	Mode picker (as switches)

What people report

OpenSprinkler controllers are polled locally. Old firmware (2.1.7 and earlier) was broken by the 2.0 calendar feature then fixed; accented characters in program names broke connection on firmware 2.2.x.

OpenSprinkler	Works Local	Made for HA; installed right away and works great Saved copy I would suggest you try OpenSprinkler. It is all open source and works great with HA using the OpenSprinkler integration. This integration is not a hack. It is made just for HA by the OpenSprinkler people. I am reasonably certain that it is entirely esp32 based. It installed right away and I love it! It just works great! I was going to make my own esp32 based system. I am sure it would have worked great. This was simpler, easier and required no experimentation to get it right. It just worked! I hope this helps!

OpenSprinkler	Works Local	Reliable for years, little firmware activity; several users confirm Saved copy As a user i would like to see more active development, however the latest firmware is. From November 2023 https://github.com/OpenSprinkler/OpenSprinkler-Firmware/releases All that said. It does exactly what i want. If you want a product id say go for it. You can easily make your own otherwise except for some of the advanced stuff like weather interupts and water lenght adjustments may be a bit of a challenge for a simple esphome implementation.

OpenSprinkler irrigation controller	Works Local	Runs locally with weather-based scheduling and HA integration Saved copy … RainMachine is a local integration so that at least would make it a contender IMO. All of the devices on the RainMachine web store are well north of $100. My controller was less than 30 bucks. A buddy got a LinkNode R8 for less than $20. Originally, I didn't want to spend a bunch of money on something that could be done for significantly less. Plus with anything that relies on a cloud service, you never know if you're going to wake up one day and find out that the service that you have built a ton of home automation around now costs a monthly fee or API access has been disabled.
