Home automation
(aug 2012 – mar 2017)
Company: Edisio / Dio
Website: http://www.edisio.com
Description:
• A belgian company which developed some home
automation devices (light controllers/dimmers,
buttons, switches, temperature/motion/door sensors.
• They used the sub-1G RF technology on 868.3 Mhz.•
Another application was a home video-interfon, based
on the Hisilicon chip, SIP/VOIP technology. The outdoor
device had a camera and a button and the connection
via SIP was finalized as a voice/video call into a
smartdevice (a phone) with an Android/Ios application.
The user was also able to control a relay from the
application in order to unlock/open the door/gate.
Responsabilities:
• embedded SW for the STM8L1xx CPUs (used in home
automation sensors/light controllers / dimmers) –
developing of a bootloader for OTA update
• uCLinux – C programming for the HI3518 CPU – handling
SIP protocol, audio/video setup for the established call
