j.rieff Posted July 7 Share Posted July 7 Just wondering if anyone has some good suggesitons on how to get a reasonable "long" battery life from Battery type 123 when using a Motion Sensor 2. I have several Motion Sensor 1's installed controlling outdoor lights like the driveway, patio, front door, etc. They are setup to trigger only at night. The 9v battery lasts quite a long time even in the furnace temps in the SW. I have 2 installations of Motion Sensor 2 controlling lights in hallways. The first one was installed as a Motion Sensor 1 because the ISY firmware had not been updated at the time of the installation. The 2nd Motion Sensor 2 is installed as a Motion Sensor 2 since it was installed after the firmware update. The traffic in both hallways is very similar. The first Mortion Sensor 2 battery will last as long as the 9v batteries in the Mation Sensor 1. I am lucky to get 4 weeks out of the battery in the 2nd Motion Sensor 2. Any suggestions?

Techman Posted July 7 Share Posted July 7 Have you changed any of the parameters in the 2nd sensor? What is the 2nd sensor controlling? You could try a factory reset, restore device on the 2nd sensor. The batteries should last as long as the 1st sensor unless something is constantly triggering the sensor.

j.rieff Posted July 8 Author Share Posted July 8 i changed 2 parameters - Ramp Up/Down time and the time interval for OFF. The sensor is controlling lights in the hallway - 2-way switch configuration. To the best of my knowledge nothing other than someone in the hallway is triggering an event.

Techman Posted July 8 Share Posted July 8 I've not used the MS2, but a long ramp up/down time might be draining the battery. Try setting the ramp time to default to see if that makes a differance. Quote Link to comment Share on other sites More sharing options...
ELA Posted July 8 Share Posted July 8 below is a page from some testing I did back in 2019 on the MSII current demand. Upon motion the sensor comes out of "sleep mode" and consumes a fairly large current while awake for 5 sec or so. Battery life will be directly related to the number of motions sensed. Likely more in a Hallway of course. Compare your settings of each sensor to see if one is different for some reason. I get fairly good battery life on mine but they are not used for Hallway type traffic. On my sensors I turn the LED brightness as low as it will go. Mine only report at night and only report the "On" to keep the number of wake cycles lower. Quote Link to comment Share on other sites More sharing options...
paulbates Posted July 8 Share Posted July 8 It may not be possible for your installation but I plugged mine into an old iPhone charger and a micro usb cable from amazon. Installed it 6 months ago and have not thought about it since. 1 Quote Link to comment Share on other sites More sharing options...
larryllix Posted July 8 Share Posted July 8 Yeah, I moved and downsized, but it saved me a bulk package of batteries every year and the hassle of changing some of them on ladders. 1 Quote Link to comment Share on other sites More sharing options...
