In principle, all rain sensors work on the same principle: a container collects the water and when a certain amount is reached, a switch is triggered. But not the RAIN-CLIK sensor from Hunter, where the impulse is triggered as soon as it starts to rain. This means OpenSprinker reacts much faster. Any ongoing irrigation will then be stopped immediately. Connect the rain sensor: The […]

Firmware for OpenSprinkler 3.0 and 3.2 has been released. You can download it here: https://github.com/OpenSprinkler/OpenSprinkler-Compiled-Firmware/tree/master/v3.0 Among other things, a memory leak related to the weather interface has been closed. Attention: BEFORE UPDATE, save your settings using the “Export configuration” function! The update may delete all settings! Here's how: Download the firmware file. Then […]

With OpenSprinkler there are several ways to control irrigation dynamically: A) With sensors: With a rain sensor With a soil moisture sensor (from firmware 2.1.9) In combination rain sensor + soil moisture sensor (from firmware 2.1.9) The sensor control is built in such a way that irrigation is prevented in the event of a sensor signal. B) With weather-specific method: “Zimmerman” method: You specify what 100% irrigation [...]

There have been strange problems with the PayPal payment interface for a few days now. Either “a technical problem…” appears or the redirection to PayPal is canceled. The reason is the switch to PayPal Plus. The manufacturer is already working on a solution. If the problem also occurs for you, then select the option “PayPal […]” under “Select payment method”.

I have covered it here: EU and sales tax For commercial customers from the EU (but outside of Germany) it is important that you indicate your sales tax identification number (UstId) in the delivery address. Then the invoice will be reduced to 0% VAT.

When delivered, OpenSprinkler 3.0/3.2 displays the time in Boston. The unit “Fahrenheit” is also displayed instead of “degrees”. This is because OpenSprinkler uses the settings from the respective region. Under “Edit options”, then “System”, then “Location” select your location and confirm with “Submit”. The time should then be set correctly straight away. […]

Until now there was only the AC version with Ethernet, now new and immediately available: OpenSprinkler3.2 DC version with Ethernet! As usual, a 7.5VDC adapter is used here, which is included. By default this now delivers 3A and is therefore much more flexible for any type of installation. Thanks to DCAC booster technology, […]

There is currently very high demand for OpenSprinklers 3.0/3.2. New goods are on the way, but subsequent deliveries are already covered by the outstanding sales. Unfortunately, this means longer delivery times. The import process from the USA depends on the processing time of customs. It's never possible to estimate how long it will take. Sometimes it's just hours, sometimes [...]

OpenSprinkler already has an input to connect external sensors. In principle it works like this: If watering is pending, it is checked whether the sensor allows it, then watering starts; if not, then not. So the whole thing is a yes/no game (digital). There are a variety of solutions on the market, but none seem to me [...]
