@tbowmo said in At home / away?:
That only detects if your car is there or not.. If you take your bike, or just walk to a bus stop, then it won't detect your presence
That's not a problem for me (I rarely ride my bike, and there's nowhere close by to walk to). Also, I rarely go anywhere in someone else's car.
But, for those instances, I figure that a simple solution would be a special event that I run from the HA app.
Well, I have an idea that might work!
Attach this to an Arduino. (Note that there's also a UART version.) Then, all I need is a Bluetooth transponder beacon tag (which I'd leave in the car).
Conveniently, I'd still need MySensors to implement this!

Passive RFID doesn't have the required range (a max of ~1 m?)
@zboblamont
BT sounds good. But, I don't exactly want to use my phone's BT (would have to keep it on).
Perhaps there's some kind of BT device I can put in my car (powered when running), and connect to something that can talk to my HA system.

I don't really like the geofence method -- I rarely have location turned on.
@tbowmo
Actually, that's what I have now. Tasker watches for when my phone's wifi connects and disconnects from my LAN, and notifies my HA system (which has a Tasker plugin). But, as @Yveaux mentioned, it's not quite ideal.
@dbemowsk
I think that Tasker knows the difference between 'wifi radio on/off' and 'connected/disconnected from and near/not near LAN'.
Hello.
I'm new to MySensors. I have a Z-Wave system (Homeseer), and would like to tell it that I'm away, and that I've returned.
I researched RFID, and found a system that would do it (UHF, active transponder tag). I even found an inexpensive interrogator ($150).
But, I'm wondering if MySensors would be better suited for this project. And, I have 4 other projects for my MySensor network, to augment my Z-Wave system.
Has anyone tried this?
Being new to MySensors, I think that the only way to accomplish this task would be for me to put a node in my car (powered when the car is running), and for the system to watch for the loss/reconnection of that node. Is that practical?

I'm just getting started in the world of MySensors, so I have some questions about which hardware to use.
I've settled on RFM69 for the radio. Trying to pick a model, I found many variations: W, CW, HW, and HCW. I believe that H is high-power. Is there any real difference between the W and CW? I know that they differ slightly in size, but I'm wondering about actual usage (e.g. pinouts, features).
Regarding the arduino, the site mentions that we could use the Uno, Nano, and Pro Mini. Can we use the other variants (e.g. Micro, Trinket, and Pro Trinket)? (Yes, I know that there are a bunch of other boards; I'm interested in alternatives to the small boards, for use with sensors and such.)
Well, I thought that I had this figured out.
@Nicklas-Starkel
But, that's an ethernet gateway; don't I need a serial gateway?
@FotoFieber
I have a controller -- the Raspberry Pi.
Yeah -- I'm just a tad confused. 
This is the post that got me on this concept:
Advice on how to start my IOT project
In the first reply, Mikael mentions an alternative setup.
Apparently, I didn't quite understand what he meant there. Please explain.
I have a Raspberry Pi running my HA system (a Hometroller Zee S2, which has Homeseer version 3). It uses z-wave, which can't do some things that I'd really like to do -- so I need to augment it.
I read (on this forum) that I could use mqtt instead of a gateway. Is this OK? I'm concerned that the 2 systems would be a big load on the cpu.
Regarding the quantity of devices on my 'completed' system: I figure that I'll have about 10 - 20 z-wave devices, and about 5 - 8 mysensors.
I'd like to use mqtt because it's more elegant; I believe that the radio (probably an RFM69) would be inside the case, as opposed to gateway+radio plugged in to the usb.
