System Requirements

System requirements for OpenSprinker 3/3.x/Pro variants AC/DC/Latch, OSPi and OpenGarage

The OpenSprinkler products OpenSprinker 3/3.2/AC/DC and OSPi all use the same software. With the OSPi, additional software is necessary due to the connection with the Raspberry PI. The system requirements for the central functions for the products mentioned are presented below.

1. Internet access is required for the weather service. The weather service has the address http://weather.OpenSprinkler.com/
2. Without internet access, OpenSprinkler can only run time-controlled programs. However, it is possible to carry out corresponding automatic program adjustments using soil moisture and rain sensors
3. Without internet access and without a network or WLAN, OpenSprinkler (not OSPi version, this depends on the Raspberry PI) and OpenGarage can create their own WLAN even in access point mode. The OpenSprinkler can then be configured using a smartphone, laptop or PC with WLAN. Remote access cannot take place here.
4. This is available from firmware 2.3.0 OpenThings.io cloud service, which makes it easy to access from anywhere!
   Without a cloud service or for older firmware, the following applies: Additional technical measures are necessary for remote access outside of your own network or WLAN. Remote access requires the following options and knowledge:
   – IPV4 Internet access with the ability to define and use port sharing. For a dynamic IP address, a Dyndns service (e.g. DynDns, MyFritz, NoIp etc) should be configured.
   – ALTERNATIVE: If the above is not possible, you can use a VPN, e.g. Hamachi (https://www.vpn.net), a connection can be established between the end device and OpenSprinkler. End-speaking devices and services must be purchased; additional costs may apply. Hamachi is also available for the Raspberry PI.
   – Special case of LTE router: Most LTE service providers do not allow remote access to the LTE router’s IP. There are special (IOT) providers for this, such as ThingsMobile (https://www.thingsmobile.com) or Vodafone Easy Connect (https://www.ioteasyconnect.de). Here you get a SIM card for an LTE router that enables remote access. Optionally also with a fixed IPV4 (ThingsMobile) or a VPN (Vodafone Easy Connect).
5. Access options: From the PC via web browser, via smartphone via Android or IOS app
