Hello,
I'm thinking about design my own smart home heating system.
Main problem I hit is wireless controller for radiator valve.
There are products like this:
https://www.eq-3.com/products/eqiva/radiator-thermostat-model-n.html
Where can I set schedule for all week.
However I would like to control valve by myself (using e.g. Bluetooth LE).
1. I think about buying eqiva valve, throwing away electronics and made my own.
a) I am thinking about controlling it by BLE protocol, so I am planning use nRF51822.
Maybe you know other wireless, low-energy consuming, low cost and easy to program boards. Then please, tell me.
b) Another problem is controlling motor in this valve. It must detect when motor reach end.
I think current solution detects high DC current when motor is blocked.
b1) There is any way to detect it using only nRF51822 boeard.
b2) I found such microchip which measure DC current:

However it needs over 3V as power supply and this thermostat is designed for 2 AA baterries (2.4 V) and don't want to change it.
Do you know any other chip?
Thanks in advantage for help
