How to Mysensors.

---

Hello,
I see many nice things about mysensors plugin but is there a HOW TO for this.
I would like to use it for PIR and measuring old gas,water and electricity meters. The meters are not on the same place as the RPI with pimatic. Is mysensors the best way to do it.

Thanks gerrit.

@ghv You need to build a mysensors serial gateway: http://www.mysensors.org/build/serial_gateway

How to connect the radio: http://www.mysensors.org/build/connect_radio

build a electricity meter: http://www.mysensors.org/build/pulse_power
build a water meter: http://www.mysensors.org/build/pulse_water

Can’t find a simple gasmeter but you have to know something about electronics and programming arduino’s.

Here you can find all the device examples for the config:

Thanks sweebee for the answers. I think the hardware will not be the problem but the software. Do I only have to put the nano with the sketch in the raspbpi like the nano of 433mhz and install the plugin of mysensors.
I also make some 433mhz PIR like your idea. Thanks and nice work. I will try this next weeks

The mysensors gateway (arduino nano with NRF) works like the the homeduino arduino nano.

You can program the mysensors gateway on your computer.

Just a little question sweeBee. I have running on the pi a homeduino with a 433mhz transmitter for the kaku stuff. Now I liked the mysensors stuff and I was checking there and it showed me a nice transmitter But that is 2.5ghz.

The question is can I build a gateway for mysensors and connect it to my pi next to my homeduino?

Thnx

Yes, that’s possible, you can use another arduino nano where you flash the my sensors gw on and connect it to your pi

Thank you. Now I have a lot of work to do 😁

I have made a lot of sensors. For beginners and people that already have made some sensors will find out that its annoying to attach the radio cables (quite a lot). So I ordered some:

NRF24L01+ smd 1.27mm (mini)
NRF > arduino pro mini shield

Haven’t received them yet, but this makes soldering sensors much faster and easier Just wanted to share

example:

@sweebee
very nice! what do these shields cost?

@leader21 2.25 dollar per 3pcs. free shipping.

I’ve ordered 12 of them
And a few of those nrf modules, now I can compact my sensors even more!

@sweebee : I don’t understand. When I look for example at this set, It comes with antenna’s (the gold zig-zag) at one end.
What do you mean with “radio cables”? Are you talking about the antenna(s) or something else?
And why would I chose the “NRF24L01+ smd (mini)” you are referring to? Are they better?

@Harry-van-der-Wolf the shields i ordered have place for the nrf smd versions, they are much smaller than the default nrfs. This shield can be soldered directly on the pro mini. Normally you have to solder all the wires from the nrf to the pro mini. Soldering one is fine, but soldering like 10 nrfs is killing. And with those shields and smd nrfs it’s much smaller.

@leader21 i found out that I ordered the wrong nrfs. I placed a link of the 1.7mm version. There is even a smaller version that the shield needs (1.27mm).

OK. Now I understand. I had not recognised the pro mini in the image you shared. I thought it was another “something”

Shields arrived. Now waiting for the nrfs.

@sweebee
thx for the info! i ordered some of the shields and nrf. now let’s see if i can finally make the step into the mysensor world

@sweebee Nice!
What is the type of the PIR on the photo? And where can these be ordered?

that’s a standard HC-SR501 as it seems.
If using this on 3V you will have to do some adaptions.
you can have a look here http://forum.mysensors.org/topic/225/hc-sr501-motion-sensor/25
or maybe @sweebee gives a short description on how he built it?

Its a normal HC-SR501. I just modified it so it could fit in my case and it works on <3V

I removed all the headers and rewired the left capacitor (removed the capacitor and put wires between it) so it fits tightly in my case.

In my bookmarks I have this connection. I have not tested this.
