I was working on something like this about 2 years ago and it still works for me for about 6months or so on 2xAA. Please, check the following github project page https://github.com/endysh/Wireless-PIR-sensor With some improvements (I did not have a chance to finish yet) the power consumption in detection mode can be reduced down to 60 - 70 uA, which can give you 1+ year, but it depends on traffic and how often it will send notifications

@Yveaux It's the Temp Sensor. All I had were the waterproof ones.

@thumper I am not sure about LiPo and Solar or battery power in general. I had to use two separate 5v power supplies, one for the Arduino and one for the servo. Otherwise the pro mini would reset once the servo kicked in to open/close the blinds. My sketch never sleeps it always listens for commands sent from the Vera, either manually or PLEG commands at dawn and dusk. Hardware List 1 - Arduino Mini Pro v3.3 1 - 220uF Capacitor (NRF24 across 3v and GND 16v+ rating) 1 - 470uF Capacitor Optional (Servo across 5v and GND 16v+ rating) 1 - Servo (Micro 25.0 oz-in [1.80 kg-cm] minimum) for selectblinds.com 1" Faux Wood Blinds 43"x38" 1 - NRF24L01 Wireless Transceiver Module (flat or antenna version) Beaware of power limitations when using the NRF24L01 antenna with LNA+PA 1 - Kimbrough Internal Rotary Drive Control System 500 NIB - connects servo to blind rod (may differ for you blind type and servo used) http://www.ebay.com/itm/291084936296?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649 1 - DC power supply you may need to step-up or step-down for the servo 5v and 3.3v for the NRF depending on the Arduino board you use http://www.ebay.com/itm/321408108698?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649 is the one I used to power Arduino and servo separately. If you are successful with LiPo and Solar combination, let us know, as it would be nice no to have the power wires hanging. Thanks

@sundberg84 I also on my last work removed the LG33, it's faster Well this most likely have been provided as info, but else it's here: Remember to burn new OPTIBOOT 8MHz into the Arduino Pro Mini and then I also use avrdude with a usbtinyISP to set the fuse to not check battery voltage monitoring, this is done after I have flashed this with Arduino IDE avrdude -c usbtiny -p m328p -U efuse:w:0x07:m```

Thanks That might have been my issue. I did notice the 5v step-up LED seemed to brighten at times, which I never noticed before. This sensor is a Micro Pro 3.3v with step-up to 5v for the sensor. It is powered with a 5v 1a wall plug. Anyhow I recompiled the sketch removing the EPROM write after trying some pull down resistor values, no luck, put it back in its original location and so far it has been working fine. Will have to watch it for a while.
