Yea from my calculations i would need to change batteries about once a month.
And with the amount of sun here in sweden i don't think solar charger would help much sadly.

RE: Parking Sensor
Even if it's only active for about 3-4minutes per day?
The problem is i got no way of getting power to where i want to place it.
And also if i did it would have to be something like 230V to usb adapter.
And plugging one of those in outside seems like a fire hazzard (even indoors they are known to start fires).
What if i hook it up to a small solar panel to charge the batteries?
Otherwise i guess i'll just have to stick with the old tennisball on a string method
i am building my own HomeAutomation system with nodejs where i will controll zwave(using razberry api) 433mhz with tellstick connected to the pi.
and now i'm also looking to implement mySensors.. so i am woundering how / if i can use mysensors with my node projekt ether directly or over mqtt ( running mosquitto broker on the raspberry ).
Basicly... is a controller like vera for example needed or?
If anyone got any tips or ideas id love to hear them!
