The OSPi is enjoying increasing popularity. No wonder, because the new firmware, which can operate remote access and analog interfaces, makes irrigation control now fun. The first OSPi version before 2021 had an acrylic parts set as a housing. Unfortunately, it was no longer possible to offer the case at that time due to huge price increases. However, we now have […]

For a few days now there have been increasing requests that the OSPi would no longer switch the outputs. The reason for this is the changes in the Linux kernel, which simply removed support for the Raspi-GPIO module. And that's exactly what OpenSprinkler-OSPi needs in order to be able to switch the GPIOs. 06/14/2024 ATTENTION: The original firmware has already been adapted! Update […]

With the new firmware 2.3.1(150), LoRaWan, NB-IOT and other external sensors can now also be integrated. However, the prerequisite is that they hand over their sensor data to an MQTT broker; OpenSprinkler can then subscribe to this as sensor data. The sensor is integrated with its “topic” and a text/JSON filter. The irrigation controller can then use this value. This is how it works […]

If you have an (older) OSPi with a PCF8591T chip, you're in luck: The analog connections can be used to also record analog measurement data. e.g. you can use the SMT50 […]

Have you reactivated your OpenSprinkler and now want to adjust the programs, but the menu is empty or cannot be opened? Then you probably gave a beta firmware version from last year. Since the OpenSprinkler app was automatically updated, it no longer matches the firmware. However, solution is quite simple, update the firmware […]

There are no clear specifications or guidelines on how to implement dynamic weather control. In principle, the OpenSprinkler is just the tool, you have to work. That means trying things out until it works. Up until now, the weather service and the “Zimmermann” or “Evapotranspiration” adaptation type were a good way to dynamically implement weather-dependent control. Due to the […]

The Waveshare instructions can be found here: https://www.waveshare.com/wiki/RS485_TO_ETH_(B) In principle, you just have to connect the Waveshare and install the software. Then set it up as follows: Start VirCom, “Device Management”, then the device should appear. Configure the device with “Edit Device”. You can freely choose the port, e.g. 502 or 8899 or completely different. Important: Firmware 2.3.0.(135) or […]
