The USR-W610 has the advantage that it also comes with the right power connection for the sensors. Up to 32 sensors can be connected to a Modbus connection of a USR-W610 (a more powerful power supply unit may be necessary at the maximum expansion level). Currently, only the Truebner SMT100, the Truebner Aquaflex and the Truebner T100 in RS485 Modbus versions supported. [...]

Here's the report: Opensprinkler Irrigation computer in the test

1. Activating the UI The prerequisite is firmware version 2.3.0(x) (or newer) with Analog Sensor API extension. So that you OpenSprinkler To use the analog sensor configuration, the UI configuration must be adjusted. Please note: There is no manufacturer support (from the USA) for the modified firmware, only via the German support page! a) OpenSprinkler [...]

Note Supported from firmware 2.2.0 OpenSprinkler 3.x remote access via OTC tokens. Please note that this is only for OpenSprinkler-Hardware 3.x is available, it is NOT available for OpenSprinkler-Hardware 2.x or OpenSprinkler Pi (NEW with firmware 2.3.1(161+) also with OSPi) / Beagle / Demo. Therefore this article is only for OpenSprinkler 3.x relevant. For OpenSprinkler 3 [...]

Features: 8 analog sensor inputs with the range 0..4V Outputs: 5V and GND for powering the sensors (7 additional 3,5V) Can also be combined with up to 4x zone expanders Maximum ONE analog sensor board per OpenSprinkler 3/3.2 16 bit digital analog to digital converter (2x ADS1115) Compatible e.g. […]

We are asked the same question over and over again: how many solenoid valves can it handle OpenSprinkler open at the same time. But the answer is always "it depends", because the solenoid valves from different manufacturers have different performance values. I got to the bottom of the matter and did some tests as an example. a) With the OpenSprinkler AC and the […]

For the OSPi (OpenSprinkler Raspberry Pi version) a suitable housing is now available. The case is 3D printed and a perfect fit. Features: 3D printed 100% match OSPi Available in 2 different colors for the common Raspberry PI 3/4/5 or Zero-W! Stable base plate The green plugs can still be easily removed and plugged in again - for a […]

OSPi is available again! However, we can only offer the variant without a housing - but at a lower price. From November we will offer our own housing - 3D printed.

An interesting article about the OpenSprinkler here: What are OpenSprinkler and OpenSprinkler Pi and who do they make sense for?

UPDATE: Information out of date, OSPi now uses a different interface. Please OSPi Update software if the problem persists. Currently the firmware works for OSPi NOT yet with Raspberry Pi Bullseye. The problem is, the required "WiringPi" library is no longer included. Use the legacy version “Buster”: https://www.raspberrypi.com/software/operating-systems/ Details here: https://github.com/OpenSprinkler/OpenSprinkler-Firmware/issues/196 However, you can […]
