2420M Motion Sensor

[MrMagic]

I find myself still somewhat confused about how to use the functions of the 2420M Insteon Motion Sensor.

There are 3 buttons that will link to HCA.
Button 1 returns the trigger
Button 2 I assume returns the sensitivity
Button 3 I assume returns the battery status

Now maybe I'm missing this in the docs someplace but:
1. How do I test/set the sensitivity in an HCA VP Element? Or can I? If not, how is button 2 of the motion sensor used.
2. How do I test the battery status of the sensor in a VP element? Or can I?

If anybody has any examples of how this is done, I'd sure appreciate seeing how it's done. I'd really like to get an alert or something when the battery starts getting low in the little monsters because when they go, they go fast.

Thanks

Hey steve,

I just got one of these devices as well and I'm curious as to what you found out from your testing... where you able to answer your above questions.

Also do you have any programs you could share which use it.

Thanks!

There is mention of the following in some documenation on the Smarthome site, which seems to align with what I'm seeing in the log file i e.take this with a grain of salt: :)
Doc ------ Log ---------- Meaning
Group 1 = Button 0: Motion Sensor On/Off
Group 2 = Button 1: Dusk/Dawn Off=Light > 3 min, On = Dark > 3 min
Group 3 = Button 2: Battery Indicator Off = Good / On = Low Battery

Group 3 seems a bit odd, but because if you miss it and the battery goes bad, it can no longer send low battery, but I suppose the reverse would cause Group 3 "Noise"

Can anyone verify?

This is my understanding. You can create programs that trigger on group 1, 2, or 3.

Don't forget that HCA can only update the linking table in the device if it can send / receive extended commands. And those are only available from the 2412/2413 PowerLinc and NOT the 2414.

I'm having an odd result from one of my 2420M sensors. Every time it detects motion I see ON commands from both button 0 and button 1 and both trigger my program that is set to only trigger via group 1 (button 0). So what happens, half way through the program exe it starts over, which achieves the same result, but it generally causes a no ACK from a controlled device I'm assuming due to the fact it sent a REQ and the program was terminated and restarted before it received the response. Not to mention it lags the actually final ON commands to the devices. (it also sends two for OFF commands)

This is odd because I have an identical 2420M in another room setup basically the same way and it works fine, button 0 ON and that's it. I tried doing factory reset on the offending sensor and no luck. I also tried unlinking the 2nd button from HCA.

I also found out an interesting fact while talking to smarthome tech. The jumper for software control overrides all manual settings on the device. This explains why I never could change the delay time. Apparently HL2 can remotely change all the settings. This would be a really NICE feature in HCA....hint hint... ;)

Well, it seems now I have somehow managed to get both of them doing it. I thought it might me something to do with the daylight setting, but I only have my programs set for group1 triggers. I also tried the daylight setting at both extremes, no effect.

I set the program to ignore instead of restarting and no longer get the No ACK from the lighting device or other ill effects, but still see the button 0 ON command show up in the log while the program is executing the button 1 ON command which comes first for some reason. I previously had a delay command in my program that required me to over ride and restart on a new trigger. This is a work around fix to ignore triggers while exe but there is still an issue here.
