Switchable Power Outlets

[Machriam]

Needed Components

RF Transmitter and Receiver like the following:

433 MHz switchable Outlets with remote control
Renkforce 433 MHz Switch

• Jumper cables, Resistors, Breadboard

Wiring Diagram for reading out Codes of a given Power Outlet

See Link

Production Usage

• When no Receiver is used - for example in production - then Pin 38 should be shorted to Pin 40. This ensures, that a ReceiveTest-Script can still verify, that the transmission hardware is present and update the capabilities of the device accordingly. See here
• The Gateway Server must know the capabilities of each device to coordinate how to restart the devices

Changes of Pull Request #94

Commit messages for #93

• 09e54b4 Added scripts to Switch power outlets on and off via 433 MHz Transmitter and a test script, which checks on another Pin, whether something is sent.
  The ReceiveTest.cpp script has the function to check whether a given raspberry pi has the capability to send data. Only if this script shows a result after starting SwitchOutlet, a given device may be used to switch outlets
• 31fe28c removing unnecessary weather forecast controller from template
• 640ee20 updated datamodel to include automatically the codes for renkforce outlets in the database.
• 02ea168 added api on device to switch power outlets and check whether the device has the capability to switch power outlets.
  Beware of differences between WiringPi Pin configuration and the default one on raspberry pi. The WiringPi configuration is necessary for the scripts to switch the power outlet
• 0922d16 The health api is now a bit more fine granular. Only when a check request is issued, the device actually checks its devices. Else only the last stored json will be returned.
• a16354e the gateway server supports now explictely rechecking of devices. This is usefull for example before an imaging run or when something has errored beforehand.
• a61cc5a datamodel does now support associating device with the respective power outlets to switch
• 3b1a2eb Minor fixes and added new functions to frontend typescript api file

• 55c76a5 Fixed some timing issues. Never multiple signals should be send at the same time, as then switching of power outlets might not work anymore.
  Javascript foreach loop does not await, even when declared as async and an await statement inside.

• a05a591 added more error handling.
  When the first call to power the outlet fails, successive calls to other devices should still work and should not issue an alert
