Wireless remote irrigation control

A method of controlling irrigation through an irrigation control system comprising:

• wirelessly communicating, by an irrigation control application stored and execute on a mobile device, with an irrigation controller, via a wireless adapter over a first local wireless network, and providing, by the irrigation control application, a remote user control interface of the irrigation controller, wherein the irrigation controller is configured to control irrigation by outputting control signals to a first set of one or more water flow control devices;
• causing a presentation, by the irrigation control application through a display device of the mobile device, of a user interface, wherein the user interface comprises a plurality of device cards, wherein each of the plurality of device cards is a user selectable representation of a respective one of the irrigation controller or one or more irrigation system devices;
• providing respective access, through the plurality of device cards, to user control options to control the irrigation controller and the one or more irrigation system devices;
• allowing receipt, via a user input device of the mobile device, of user input to select one of the plurality of device cards;
• and
• causing a presentation, via the display device of the mobile device and responsive to the receipt of the user input, of a device user interface displaying the user control options.

An irrigation control system comprising:

• an irrigation controller at a site to be irrigated, wherein the irrigation controller is configured to control irrigation at the site by outputting control signals to one or more water flow control devices;
• a wireless adapter cooperated with the irrigation controller;
• and
• a server in communication with the wireless adapter via a wireless local area network at the site, wherein the server is configured to:
• receive, from a first mobile device associated with a first user operating an irrigation control application executed on the first mobile device, an authorization to allow a second user operating the irrigation control application to be executed on a second mobile device to gain access to and control the irrigation controller via the wireless adapter using the irrigation control application on the second mobile device;
• create an access token corresponding to the authorization, wherein the access token defines a criteria corresponding to authorization to allow the irrigation control application executed on the second mobile device to gain access to and control the irrigation controller using the irrigation control application executed on the second mobile device;
• store the access token, wherein the access token is not transmitted to the irrigation control application of the first mobile device or the second mobile device;
• receive, from the irrigation control application executed on the second mobile device, a request from the irrigation control application executed on the second mobile device to access and control the irrigation controller;
• determine, using the access token, whether the criteria corresponding to the authorization has been met;
• forward, when the criteria has been met, control communications from the irrigation control application executed on the second mobile device to the wireless adapter via the wireless local area network to allow remote access and control of the irrigation controller;
• and
• prevent, when the criteria has not been met, control communications from the irrigation control application executed on the second mobile device from being communicated to the wireless adapter via the wireless local area network.
