I need your 2c on this notion here…
Internet of things is a concept I really buy. Home automation in the form of intelligent lighting, heat control, devices which you can ‘train’ to learn from your behaviour (yes, I’m mainly targeting my coffee-machine here).
So, for a start I want to replace my AC switches and heater thermostats in my house. And I want to use the .net Micro Framework to do it. Thing is, I have a goal that the electronisc of each unit, switch or thermostat, shall only cost $20 tops to replace. This on grounds of volume: I have approx 25 switches and 7 thermostats, equals 32 times $20 = $640. It all adds up.
So I’m beginning to think of how to go about it. The requirements are 1) it must be .net Micro Framework and 2) it must be a wireless solution.
I’m thinking RF and a relay for the switches, RF and small servo-motor for the thermostats. That’s max $10 in parts. That leaves $10 for a .net-enabled micro controller which needs only one SPI and two-three GPIOs and Analog Inputs. Possible? I’m reading a page on mountaineer.org’s site which states that “We have ported NETMF to the STM32F1”. Might be a way to go?
I would much appreciate your thoughts on it,
and I thank you in advance.
