General Discussion

Yes you can but only with the development version. See http://forum.mysensors.org/topic/2574/how-to-use-the-development-branch-for-sensor-and-gateway/ http://forum.mysensors.org/topic/2794/connect-sensors-directly-to-the-gateway-again/ http://forum.mysensors.org/topic/2122/sensors-without-a-gateway/ http://forum.mysensors.org/topic/1387/sensors-on-gateway/ http://forum.mysensors.org/topic/1338/gateway-and-sensor-node-on-same-arduino-is-it-possible/

@Ironbar yeah I'm in that process now.

Great! Thanks for reporting back :)

@punter9 Thanks for the link, that gave some good background info, and some hope that those of us who are interested in playing with it will eventually be able to get one. (By pure chance, I happened to stumble across it minutes after it was first released, but didn't order one as I didn't have an immediate need, and I already have too many processors which I bought hoping to find a good use for already! Nevertheless I'll probably get one someday.) I wasn't commenting on the quality of the hardware, just on the suitability for our purposes; parts which are only available in quantity one every few months IF YOU ARE LUCKY have some limitations. From the article you linked, perhaps that will eventually change. We'll see. how soon. It's so cheap that if they don't keep limiting the quantities, one customer could buy up the full month's supply for embedding in a commercial product. I'm wondering how it would be useful to us in DIY home automation tho. As a node, I'm not seeing it as a major contender. Let's compare it to an Arduino Pro Mini (under $2 shipped). The minimal RPi zero plus memory, shipping and tax is going to be several times that. The RPi Zero as node takes a lot more power to run and will not power up and down so quickly and gracefully, so it's not going to work well with battery power (and will have a larger passive load on mains power). It tends to require a whole OS which often gets in the way of direct interfacing with hardware, and requires system administering. There aren't as many sensor libraries for it. It has a much faster CPU and far more memory, but for most nodes that's just overkill. I'm not seeing that it would be competitive for most nodes even at the same price as an APM. But there must be some special purpose home automation nodes where it would be useful - any ideas? Of course, it would work as server for some Home Automation Controller software. But you only need one of those, and how much money would it save once fitted out (relative to total system price) compared to using a RPi 3 (with built in WiFi and BLE) or RPi B+ @ $25, or BeagleBone Green? So I'm still wondering what niche it would fill, within our domain... What ideas do people have for making good use of a RPi Zero as a MySensors node, if it was easily available at the nominal price? (Understand, I'll probably eventually get one to play around with because it IS cool, but not necessarily for HA. I also have a $9 C.H.I.P. on order, and a $19 PINE A64, and a RedBear Duo, etc. But those are to feed my addiction, I don't see them as changing the DIY Home Automation landscape).

Seems a bit complicated, and as you say, will increase radio traffic. But do whatever works for you. The project is called MySensors for a reason ;)

Thanks for the quick response. I shall try the option.

No answer for this one?

Welcome to the MySensors community @garnser ! The getting started guide has good recommendations to get you started. The ir example lists which parts you'll need for ir communication. The motion detection example lists which parts you'll need to detect motion. I suggest you read the entire getting started guide, since it most likely will save you a lot of time. The forum has lots of extended discussion on both ir and motion, but I recommend that you start small and get the basic examples working before you extend. If anything is unclear, just ask away :)

OK, issue reported: https://github.com/NodeBB/nodebb-theme-persona/issues/244

@Cliff-Karlsson I use active beam detector. Power is needed on both sides though but if that is an issue you can always use mirror on the other side. In my experience these things are very sensitive in short ranges (below 5m). More expensive models let you adjust trigger time too.

@moskovskiy82 , it makes sense. Glad you ruled it out!

You just don't connect it. That's all :) The MySensors nrf code does not use the interrupt so there is no code to remove.

long previousMillis = 0; // will store last time something happened long interval = 5000; // interval at which to blink (milliseconds) void loop() { unsigned long currentMillis = millis(); if(currentMillis - previousMillis > interval) { // save the last time something happened previousMillis = currentMillis; Insert your code here... } } Note millis() does not work if you are using gw.sleep()

@Lawrence-Helm said: Another idea would be, a mysensors network strength scanner, something like http://hackaday.com/2016/02/24/quickie-wifi-scanner/ That would be cool. It could be based on http://forum.mysensors.org/topic/242/wireless-nrf24l01-sniffer-for-mysensors/81?page=1

Maybe these threads will guide you one or two steps further: http://forum.mysensors.org/topic/486/my-2aa-battery-sensor http://forum.mysensors.org/topic/2210/battery-sensor-measure-for-li-ion-cells http://forum.mysensors.org/topic/2866/battery-percentage-help-needed

Simply because I am not good at all in "coding" or writing sketches. I would have to hope someone else creates the exact sketch that I need. I saw some video where someone showed of the sensor and some "simple" code. There where alot of arrays involved and you had to write some half complicated "algoritms" to translate the different arrays of temperatures into "persons" to detect.

You can charge a battery, of course..... A small dynamo will do the job.
