General Discussion

@alowhum I've heard of geophones being used to detect footsteps outdoors. Cost was around $60/sensor IIRC. http://www.kr4.us/Geophone-SM-24.html?gclid=CjwKCAiAoNTUBRBUEiwAWje2lqjbwf7gdzmiPalzIry4JBhZ-L-kqX6qqSt4UV0atkOPNGlab9Q5ZxoC_H8QAvD_BwE

@nca78 said in Security: 433 RFX vs Mysensors security: @chbla said in Security: 433 RFX vs Mysensors security: @nca78 I'm still deciding what to use. Pro Mini if I don't find anything better. I'm interested in where you buy your BME680 breakout boards, there are not so many around :) I think I bought them here: http://www.watterott.com/de/BME680-Breakout I'm located in Austria

@cablesky it seems to be possible according to https://forum.mysensors.org/topic/1668/sending-image-data-over-the-mysensors-network/

Mysensors has a "savestate" function that can be used to save variables in eeprom without too much hassle, but in your case it since it is a mains powered node you could just report every pulse and have the controller save the data and when node boots it will just asks Domoticz the last pulse count (look at energy pulse meter example in library) but I think that will work only if using mqtt gateway as for the ethernet it will just miss the retrival of the pulse count because the controller takes some time to connect to the ethernet GW. As an alternative there are other solutions like ESPEasy that have already some built in funtions easy to use without need to do lot of coding.

You could give a try without reflashing nodes , just save the current binary :)

First attempt playing with the logo. I did a manual filament change from yellow to blue. Didn't have any black PLA, only ABS, otherwise I would have used black. This is more of a lithophane style which didn't do the best, but is still okay. I want to try to figure this out using paths in inkscape and exporting them to OpenSCAD. Having some trouble with that though. I'll figure it out in time. The picture is next to a soda can so you can get an idea of the size.

@kebibg hello Was you able to bring it to work? Thanks, Simon

@ricorico94 From the NRF24 datasheet: [image: 1518649573838-screen-shot-2018-02-15-at-00.05.12-resized.png] https://www.sparkfun.com/datasheets/Components/SMD/nRF24L01Pluss_Preliminary_Product_Specification_v1_0.pdf So, you should probably choose address a bit careful. To change base address just add a define in your sketch like this (before including MySensors.h): #define MY_RF24_BASE_RADIO_ID 0x00,0xFC,0xE1,0xA8,0xA8

Very simple solution, but I just put up a single flow (called watchdog of course) that subscribes to "hart beat" and value topics of items I am watching (in my case via openhab, but principle is the same for vanilla mqtt) and then have a "timeout node" for each item. Timeout node triggers if no message comes in in a predefined period (per item, some send data every few minutes, some every few hours) But each arduino node has defined hart-beat interval In my case all timeouts go to a function that formats a message in format "<itemname> not seen in <timeframe>" and that is logged and sent to an email once a day. But you can as well put it into a dashboard as Yveaux showed. I also like use of subflows whenever possible, but in my case all is happening on one flow and in two nodes, one that connects to mqtt hearbeat and one node that triggers if no data comes in (sorry I forgot the name, but it is a default node-red node)

I havent' seen but some one had the same probleme on the forum, and found the solution: [link text] https://forum.mysensors.org/topic/6096/problem-with-mysensor-library-on-arduino-ide-running-on-raspi/8 now i can download my sketch with the raspberry pi and i'm very hapy!

It works, thank you ;-)

@flopp electrokit is in Malmö and should be open today. Order pickup and you will have the parts later today.

@mfalkvidd Thx for the "quick and dirty" way. This at least is a starting point, but most things around that seem really to be hard coded (MySensorsCore.h: L77: GW Address is 0 is the point where the getNodeId() finally leads to). But if that really works there might be a way to wrap around that - but indeed this seems to be quite complicated. And indeed, you are right that having multiple nRF-GW's was possible ever since MySensors existed.

GW to node communication is not affected by Serial / MQTT / Ethernet interface with controller. With ethernet and MQTT you could actually connect more controllers to the same gateway, even on different computers. You can also have gateway running as a service on the RPI with radio directly on the GPIO and you can connect to is from wherever you have IP communication to the RPI (if you use the ethernet) or the MQTT broker (that could also be on another network)

@hek Thanks; maybe I'll try the inclinometer project.

@mfalkvidd Thanks for your valuable input. I think I got some direction to move on.

Sure it can be done, the only problem is the amount of flash of the pro mini that is limiting the amount sensors you can have when you have all securities enabled

Ive designed a NRF based mysensor remote with 14 keys, I want to use pin 2 for one of the key. Currently all pin work properly for key but pin 2 does not recognise instead it creates some disturbance in transmission. what i receive on destination node is unexpected. Is it possible to disable use of pin 2 . it looks like mysenso uses pin 2 for some internal use.

@gohan It's not like the drive stayed full for long. I usually ran with between 20GB and 40GB of free space.

@8667 That is inherently hard to state firmly due to so many variables. How much debug do you want, what libraries do you want to include, what software version do you plan to use, and so on.
