The use in home automation of infrared and / or radio frequency codes (433mhz / 315mhz) rappoften resents a good technique to be able to domotize something that, natively, it wouldn't be.
In fact they have existed for some time simple and cheap devices useful toappefficiency and above all the transmission of codes of this type (eg Broadlink RM Mini 3); such devices, once inserted in home automation, rappthey provide a "lever" to virtualize the indirect control of "objective" devices.
In essence, the technique is that of appmake the codes from the remote controls of the devices we want to domotize, insert them in the configuration of ours personale HUB (in this case, Home Assistant) in the form of accessories (switches, fans, air conditioners, etc.) which, when activated, arise in sending infrared / radiofrequency codes appropiati.
This technique has been used in several projets present on inDomus:
- How to domotize (and automate) the supply of gas and / or water
- Conditioner for compatible fan use Appthe HomeKits (via Homebridge)
- Domotize TV, decoder, (synto) amplifiers with Broadlink e Home Assistant
- Domotize TV, decoder, (synto) amplifiers with Broadlink e Home Assistant (V2)
- Household a traditional air conditioner with Broadlink e Home Assistant
- Household a traditional air conditioner with Broadlink e Home Assistant (V2)
- Domotize a traditional air conditioner making it compatible Appthe HomeKits (via Homebridge)
- Home automation of a non-domotic robot vacuum cleaner with Broadlink e Home Assistant
- Domotise a bathroom fan heater with Appthe HomeKit e Broadlink (via Homebridge)
- Domotise a bathroom fan heater with Broadlink e Home Assistant
- Make a strip of colorful IR LEDs compatible with Appthe HomeKits (via Homebridge)
- Make a strip of colored LEDs Wi-Fi compatible with Appthe HomeKits (via Homebridge)
What we will see in this guide is how, starting from a device Broadlink (capable of receiving / sending infrared / radiofrequency codes) and from a remote control or a radio controlor (capable respectively in transmitting infrared or radio frequency codes), we will succeed to capture these codes for the purpose of reuse in home automation configuration.
Nb. this guide refers to 433mhz / 315mhz radiofrequency codes (not rolling code) and infrared signals (with wavelengths between 700 nm and 1 mm, or that of traditional remote controls).
To domotize remote controls rolling code, is available this guide.
On the topic of the use of infrared and radio frequencies in home automation we have dedicated an episode of ours Podcast.
|ATTENTION: First to ask yourself proproblem of capturing codes, the healthiest thing is to jump on ours COLLABORATIVE ARCHIVE of infrared / radiofrequency codes. With any luck, you may already find the job done. Differently, don't forget (always through that page) after collecting yours, to send them to the archive!|
Device configuration Broadlink
Before starting the code capture through the combined use of Home Assistant and its component "Broadlink", It is necessary that the Broadlink is already present on ours Wi-Fi. In case this step has already been done previously, it will be possible profollow over.
To make the infrared emitter enter (and remain) inside yours Wi-Fi just download theappe-Control reporting for Android o for iOS and follow the instructions. In case of difficulty, it is available the manual in Italian.
At this point it is necessary to download for free "Broadlink Manager“, The small but very convenient software for capturing the codes. Download the installation package da here e prosee step-by-step installation.
At the first execution of "Broadlink Manager "click on" Scan "in order to search the device on the network Broadlink to be used for code capture. The computer on which it runs "Broadlink Manager ”must be connected to the same network as the device Broadlink.
If everything goes as it should, in the finestterminal terminal of “Broadlink Manager" appthe evidence of the automatically identified device will appear:
Nb in the title of the finestra appthe temperature of the environment in which the device has descended will also occur Broadlink (models only Pro/Pro+ RM3).
At this point it is possible capture the codes from proown remote control.
Click on "Learn New Command”To set the device Broadlink in "modelistening", Taking care to choose which type of code to capture (infrared" infrared "or radio frequency" RF "):
Once this is done, press the button on the remote control to be captured, taking care (in the case of infrared) to point it at the device.
In the finestra appariranno two codes, one green and one yellow (respectively RAW and Base64).
These are two variations of the same code: it is the use that can be made of it, to change. The first format (Base64) is usually used with Homebridge through the component "homebridge-broadlink-rm", While the second is usually used with Home Assistant (via components such as "Broadlink"Or"SmartIR“).
At this point "Broadlink Manager"Will ask to assign a" name "to the code appena captured, to be inserted in the dialog box that apparirà:
Inserted the name, at the top right this "name" appwill appear in the list of codes captured so far. Selecting one and clicking "Send Command", the device Broadlink prowill see to send the command, so as to allow us a test of goodness of the code.
Publication of codes
The codes, it goes without saying, will gradually be collected, possibly (our advice) in an Excel sheet, using a banal copy-paste starting from thenestra of “Broadlink Manager".
To this proposito we remember the existence of our "collaborative archive”Of infrared / radiofrequency codes, to which we invite everyone to collaborate as and when, starting from propri remote controls, the codes are collected.
