The ESP32 upgrade board transforms your OpenSprinkler Version 3.2 or 3.3 with ESP8266 provides a significantly more powerful and future-proof control center. Instead of just reliably irrigating, the upgrade unlocks a new class of functions for your existing controller: more processing power, more memory, modern wireless standards, and considerably more reserves for demanding expansions.

Group Scheduling Inversion — “An option that changes everything” More flexibility. Same hardware. Completely new irrigation concept. Until now, a simple rule applied: Zones in the same group run sequentially — zones in different groups simultaneously. Practical, but sometimes too rigid. From now on, you can reverse the principle. With the new Group Scheduling Inversion (ginv) option, the logic is reversed: Zones […]

We did not make this decision lightly, but with just 25 enclosures sold last year, we are unfortunately unable to offer any more. Sincerely, Stefan Schmaltz […]

Frost-sensitive plants Root heating protects frost-sensitive plants, especially Mediterranean species such as palms and olive trees, from frost damage during the European winter by preventing the roots from freezing. Since the ground freezes and the plants cannot absorb water, leading to dehydration, or the cells are destroyed by frost damage, heating the root zone […]

The OpenSprinkler It has two digital inputs, which are essentially nothing more than an on/off switch. This makes it easy to use a rain sensor to turn off the irrigation system when it rains. However, the situation is different with soil moisture. This is not a value that can be defined as 0/1. Different soils have different densities for […]

OpenSprinkler Using DC with Power over Ethernet (PoE) Occasionally, we encounter use cases where users want to leverage Power over Ethernet (PoE), which allows a single Ethernet cable to provide both network connectivity and power. This configuration eliminates the need for a separate power line and is therefore particularly useful in remote or hard-to-reach locations where running additional cables is difficult.
