The Aviosys IP Power 9212 is an inexpensive way to add 8 inputs and 8 outputs to your home automation system that are network addressable either from your LAN or from anywhere in the world via the Internet. Read on for the mini-review.
You can check the status of devices using the embedded web server on the box, or by sending UDP packets to it, for use with devices like PIRs, door reed switches, toggles switches and Key fob receivers. One drawback to the inputs is that it only allows for on/off devices so it’s not possible to have analog sensors connected to the device, such as say a thermistor.
The outputs are simply relays that can be used to switch high or low voltage appliances.
After using the device for quite a while, the main drawback seems to be the rate at which you can poll it, which is limited by the network, although it being network based is obviously a plus.
If you’re looking for a device that you can poll faster, and has analog outputs/inputs as well as digital, checkout Velleman, they provide a good range of devices that are suitable.
The current model of the IP Power 9212 is the IP Power deluxe, which features the following (on top of the standard model)
- RS232 interface with pc
- SMTP Alerts
- GPRS interfacing with, Motorola V878. C550 and Sony Eriksson T630 . K700i
- Time scheduling
- The ability to set the inputs to wet or dry individually, before you had 4 wet, 4 dry (i.e. resistance input, or voltage required for the input)
- HTTP Command line style control, with authentication
- Dynamic DNS support
- LAN Wakeup support
After contacting the manufacturer it seems there is potential in the future for a firmware upgrade that would allow the RS232 interface to be a device server, stay tuned.
