Still awaiting delivery of the RFID unit and power supply for the electronic lock so haven’t been able to make much progress on it other than running cables to the lock and position for the RFID reader. Hopefully should be here in the next few days.
In the mean time I have been playing with home automation software and think I have found the one I’ll use as it can interface not only with Insteon and X10 but any serial or IP connected device which will allow me to pull temperature, humidity, voltage and all sorts of other data into the system on which to make decisions from.
eg: turning the bathroom fan on when the humidity rises, cooling fan in the rack when the temp rises, email/sms notification of power outages, etc.
I have ordered a USB/serial connect 4 relay board that I will interface with it to allow low voltage switching for things like the Kitchen amplifier, cooling fan in the rack and also to be able to unlock the door from the automation interface. The unit is also capable of bluetooth or WiFi with a module but will be connected via USB. Picked it up for $35 on eBay.
Have also ordered a pair of DHT22 temperature and humidity sensors and a 5 pack of DS18B20 water proof temperature sensors.
DHT22’s will be mounted in the bathroom and laundry to allow automatic fan control when humidity rises.
DS18B20’s will be used mostly for data collection and also to trigger cooling fan for the rack.
I recently read about the uRADMonitor project and contacted Radu who runs the project to get on board and get a unit up and running here in Australia.
You can read about that building of the board here which in it’s self is amazing to see.
Bit over three weeks in the mail and here it is 🙂
The unit is to be mounted outside under my veranda which means getting both network and power out to the unit. I opted to do a somewhat DIY POE method to save running multiple cables.
This involves splitting out the two unused pairs in the CAT5 cable (Brown & Blue) at both the switch end and the unit end to allow power to be “injected” at the switch and extracted again at the unit end.
In my setup I have only connected the data wires to the patch panel and the power wires are connected to a length of wiring running off to the power supply as shown below:
Then at the unit end the data wires are terminated and the power wires split away for a power jack to be soldered onto.
Next came mounting…
Connected up the power and is now transmitting away 🙂
Just a quick post today, received this in the mail from China today. A USB voltage and current tester for a whole $2
Nice simple setup plug one end into a USB port and connect the device you want to the other end and the display changes back and forth from current to voltage every few seconds.
Measures 3.5-7V and 0-3A.
Lets connect it up:
Nice simple device that does what it says on the box and quite useful for diagnosing USB devices, well worth the $2 to have around for the odd time you even just want to know how much current you’re getting out of a charger.
Started on the installation of the electronic lock for the front door today.
Eventually the plan is to have RFID control as well as integrate it with the Insteon system for control from the smart phones, computers, etc.
Is pretty rough around the edges atm but it will have to come out for cables to be run to the back soon so I’ll file the edges and put some paint on make it a little prettier but for now it’s in and functional ready for the next lot of parts to arrive 😀
First read about the Chumby a few years ago but at the time it was quite expensive to get one here in Australia and so mostly forgot about it until I read an article the other week mentioning that the Chumby was back!
The Chumby is a bedside clock replacement with over 1000 apps you can cycle through from clocks, weather, Facebook, picture slide show, etc.
Shipped from the USA on Tuesday and arrived Friday morning, time to unpack it 🙂
Now time to load some “apps” up and have a play.
Eventually hope to write an app to integrate into my Insteon system allowing bedside table control of the whole house.
The Insteon Hub allows HTTP requests to be used to control devices and the Chumby uses Flash Lite so shouldn’t be too hard.
