Un-bricking a Sonoff S20

IMG_3876

A while ago I invested in a bunch of home automation stuff to augment my Google home. I opted on the Sonoff devices as they are by far the best value and also come with Aussie compatible plugs and sockets. Unfortunately one of the units was DOA.

In a bid to try and resuscitate the device I decided to have a go at re-flashing the firmware with the updated Tasmota firmware. The Tasmota firmware is a third party developed firmware that adds a bunch of features to Sonoff devices, including removing some communications limitations. This last feature is one that I'm particularly interested in installing into some other 4.22mhz transmitters so that they become more usable (communications are very limited in the Ewelink app), so this initial experiment to see if the firmware upgrade works is a bit of a test. If all goes well I'll look to update my other Sonoff devices.

Home Automation Part Duex

Regular visitors may remember me mentioning that I had been looking into home automation. My 'research' has lead me to invest in an x10 Active Home starter kit which includes a whole bunch of lamp and appliance controllers and most importantly a PC interface.

This and a bunch of other 'projects' have made me stop work on DMCMS for a while. Work on DMCMS will resume when I've finished the other more important stuff. Anyhows - back to my ramblings...

The PC interface comes with the Active Home software allowing you to program scheduled programs to control the modeules.

The modules themselves are controlled by signals carried through the pre existing power cables of the building, meaning that I dont need to run in a trillion new cables into my 80 year old house.

Home Automation

This week I've been delving a little into home automation. Home automation is a topic that I have been meaning to have a look into for quite some time. Being an industrial automation specialist, the home automation sector is a very interesting topic for me as it is something that should be relatively easy to someone of my background to do.Prior to looking into home automation I had a few pre-conceived ideas of usefull facets including modulated signals using domestic AC supply as a carrier wave. It was no surprise to see that this has been adpoted as part of the X10 standard.My personal view of home automation was to utilise a home PC, equipped as a master controller with inputs and outputs to control functions within the house such as lighting and access control. Modern Home Automation system can be much more sophisticated also including audio and video streams throughout the house.Home Automation is a relatively new sector, with relatively few companies providing off the shelf systems that can be catered to suit end user needs. With the utilisation of a development medium such as Visual Basic and a simple I/O interface or perhaps interfacing to the already available X10 standard it may be possible to greatly reduce Home Automation costs.
