Send Remote Commands to Cell Phone When You Need To Take Control

The above example creates switch. A good choice is to prefix the name with the area in which the device is located, e. Bedroom TV. Get the script from here. Open the e-Control app on your mobile device. It will generate the files you will need for the script. You need to get the following files and put them in the same folder as this script:.

Run pip install simplejson. You must install simplejson in the same Python version you will use to run the scripts. Navigate to the folder you downloaded and run python getBroadlinkSharedData. Follow the steps on screen. Test the codes Use the sendcode script you have already downloaded to test the codes you got from the device. When run the script, you know the code works when get message. Code sent… Not every code works. Convert the HEX codes to base Use this tool to convert the hex codes to base64 for use with Home Assistant.

Use the e-Control app to learn the codes from all of your suitable remotes. This will mean that you should only have to run this process once and will help with getting them quickly into Home Assistant. Dump the files in the app by navigating to the hamburger icon, select share and select , then choose Share to other phones on WLAN. Open iBackup viewer then select the iOS backup that you created. Navigate to the App icon and then scroll until you find e-control. Put these in the same location as the getBroadlinkSharedData. Now open a Command Prompt and navigate to the directory where the aforementioned files are located e.

Now run the command python getBroadlinkSharedData. Now there should be a file with the name of the remote you chose in the same directory ending in. Open that up and it will contain the Base64 code required for Home Assistant. Click install on the node-red-contrib-broadlink-control.

Click Update, and the device field should show the MAC address of the newly added device.

If not, just select it. Drag an Inject node to the left of the RM node and link them. Leave it to the defaults. Point the IR remote control at the RM device and click the desired button for about 2 seconds. An array of numbers will show in the debug window. For example:. Drag another RM node on the same flow we created earlier.

The RM node should be configured to the RM device created earlier by default. Click Deploy to activate the flow, and then click the inject button. The debug window should show a debug message. Now you can add as many template nodes, each having a specific code, and add any type of input nodes to activate the template and transmit the code. You can grab irdb2broadlinkha. Manual configuration steps. You can set up a manual integration entry: Browse to your Home Assistant instance.

In the sidebar click on Configuration. From the configuration menu select: Integrations. In the bottom right, click on the Add Integration button.

Follow the instruction on screen to complete the set up. Configuration Variables mac string Required.

A transmitter is often a light emitting diode LED which is built into the pointing end of the remote control handset. The infrared light pulses form a pattern unique to that button. The receiver in the device recognizes the pattern and causes the device to respond accordingly. Most remote controls for electronic appliances use a near infrared diode to emit a beam of light that reaches the device. A nm wavelength LED is typical. Video cameras see the diode as if it produces visible purple light. With a single channel single-function, one-button remote control the presence of a carrier signal can be used to trigger a function.

For multi-channel normal multi-function remote controls more sophisticated procedures are necessary: one consists of modulating the carrier with signals of different frequency. After the receiver demodulates the received signal, it applies the appropriate frequency filters to separate the respective signals. One can often hear the signals being modulated on the infrared carrier by operating a remote control in very close proximity to an AM radio not tuned to a station.

Today, IR remote controls almost always use a pulse width modulated code, encoded and decoded by digital computer: a command from a remote control consists of a short train of pulses of carrier-present and carrier-not-present of varying widths. Different manufacturers of infrared remote controls use different protocols to transmit the infrared commands. The RC-5 protocol that has its origins within Philips, uses, for instance, a total of 14 bits for each button press. The bit pattern is modulated onto a carrier frequency that, again, can be different for different manufacturers and standards, in the case of RC-5, the carrier is 36 kHz.

Since infrared IR remote controls use light, they require line of sight to operate the destination device.

The signal can, however, be reflected by mirrors, just like any other light source. If operation is required where no line of sight is possible, for instance when controlling equipment in another room or installed in a cabinet, many brands of IR extenders are available for this on the market. Most of these have an IR receiver, picking up the IR signal and relaying it via radio waves to the remote part, which has an IR transmitter mimicking the original IR control.

Infrared receivers also tend to have a more or less limited operating angle, which mainly depends on the optical characteristics of the phototransistor. However, it's easy to increase the operating angle using a matte transparent object in front of the receiver. Radio remote control RF remote control is used to control distant objects using a variety of radio signals transmitted by the remote control device. As a complementary method to infrared remote controls, the radio remote control is used with electric garage door or gate openers, automatic barrier systems, burglar alarms and industrial automation systems.

Most remote controls use their own coding, transmitting from 8 to or more pulses, fixed or Rolling code , using OOK or FSK modulation. Also, transmitters or receivers can be universal , meaning they are able to work with many different codings. In this case, the transmitter is normally called a universal remote control duplicator because it is able to copy existing remote controls, while the receiver is called a universal receiver because it works with almost any remote control in the market.

A radio remote control system commonly has two parts: transmit and receive. The transmitter part is divided into two parts, the RF remote control and the transmitter module. This allows the transmitter module to be used as a component in a larger application. The transmitter module is small, but users must have detailed knowledge to use it; combined with the RF remote control it is much simpler to use.

The receiver is generally one of two types: a super-regenerative receiver or a superheterodyne. The super-regenerative receiver works like that of an intermittent oscillation detection circuit. The superheterodyne works like the one in a radio receiver. The superheterodyne receiver is used because of its stability, high sensitivity and it has relatively good anti-interference ability, a small package and lower price. A remote control is used for controlling substations, pump storage power stations and HVDC -plants.

For these systems often PLC-systems working in the longwave range are used.
