LoRaWan+NB-IOT+MQTT

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 […]

dynamic irrigation control

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 […]

Example configuration Waveshare and SMT100 Modbus

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 […]

Example configuration USR-W610 and Truebner SMT100 RS485 Modbus

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 port of a USR-W610 (at maximum expansion level, a more powerful power supply may be necessary). Currently only the Truebner SMT100, the Truebner Aquaflex and the Truebner T100 are supported in the RS485 Modbus versions. […]

Activate analog sensor configuration

1. Activating the UI The prerequisite is firmware version 2.3.0(x) (or newer) with Analog Sensor API extension. In order for your 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 […]
