I've been on MySensors for some time now, and during this time I "evolved" from a guy that normally added a new outlet to my house, to someone that now understands a "bit" more of electronics and even developed and build my own IOT devices/nodes. This has been a hell of an experience, and I only have to say thank you to all the staff, developers, and community members that help not only this project grow but also all of us (intellectually and in this hobby).

I know that the main focus of this community is not to make a profit, but lets face it, every thing in this world needs a bit of juice ($$$) to make it flow. So I came up with an idea, why not add a way to sponsor this project? Something like Patreon or a membership? It would be totally optional, but the members would have access to for example give aways or something. And what would you guys do with a money? Easy free beer... ...

The money could be used to pay for hosting (damm this things can get expensive when a community grows... respect @hek) or to help guys like @tbowmo (sorry to all others just the first name that got to my mind when I was typing) to develop new prototypes and get them at low prices to all of us!

Basically this post is only to say thank you to all of you guys that helped this community get where it is, by developing the software or by developing the hardware (too many people to name in openhardware.io.

Hello all I want to share with you all a good store to get all kind of enclosures to our projects, I have no kind of affiliation with them, I just want to share somting that I find to be very useful:

https://www.aliexpress.com/store/1006252?spm=a2g03.10010108.100005.1.5d4e5be9KhrC2i

Hope you enjoy it. And you can share here more stores to get enclosures or the results of you projects in them

Hi all! I have merged 3 boards into one 50x50 layout, this way I can send it to print in dirtypcbs.com and order 10 pcb's, that will make 30 nodes! The solution is similar to the one used by @m26872

End Layout updated! I added a ATSHA204A to the board and revised the clearance on the AC side! The Varistor was reallocated to ensure the "correct" (don't know if it was incorrect in the first place) connection of traces!

I'll make my order today, it will take something like 15 days to arrive after shipping!

I'll test the PCB and if all is ok I'll publish the files for printing!

I must say that I'm not a expert (very very far from that), so if you plan to print and use this board, do it at your own risk! AC current is dangerous!

Thank you all for the ideas and tips!

Best Regards

It would be nice to, in the send function, that we could pass a extra value after the ack request, that value would be a numeric value that the gw would return back when replying with the ack. That way we could pass a unique id with the message, allowing to filter if the messages that we are acknowledging is the expected one.

id++;
send(msg2.set(state?false:true), true,id);

something like this.

Afther some googling I changed the start.sh

From This

#Java Heap settings
HEAP_MIN=-Xms32m
HEAP_MAX=-Xmx256m

To this

#Java Heap settings
HEAP_MIN="-Xms32m -XX:PermSize=32m"
HEAP_MAX="-Xmx256m -XX:MaxPermSize=256m -Xss1m"

And now the max memory is respected...

Some dev can pronounce him self if this can give any problems....

Thank You all

Hello all, I've been using m26872 slim node to some of my nodes, but my main problem was not being able to power it with 5V because the RF is only 3.3v. So I made some modifications to the design and now I'm asking for your help to see it and validate it! I'm no expert in electronics (not at all) and this is my first attempt with KiCat.

The main idea is to power the Radio with a LE33A step down regulator! Here is the result:

1_1460679153850_print.pdf

BOM
C1,C2,C3 : 0.1uF capacitor P-5mm (low to fit inside IC1 socket)
C5 : 0.1uF capacitor P-2.5mm
IC1 : Atmega328p
R1 : 10k resistor 1/4W
P4 : nRF24L01+
U1: LE33A

What do you think, will it work? My main concern is the Capacitors!

Thank you all.
Best Regards

PS: Credits and tanks to @m26872 for the base design and help

This solution, if well build locks a lot safer than a standard phone charger. The overheat protection is something that I like a lot. Is ther any pcb that only haves this solution? I found one in the OpenHardware but it integrates the node, I would like some stand alone solution! I think that I will give KiCad a go and try to develop one!

@tbowmo Sir... you are a genius .... It worked! thank you

Thank you @David-Muller

That is nice! But I would have to test it out! Probably that would make the node all the time awake during a long bath! Ok, it would not use the radio all the time, but I would like to know who that would affect the battery!

Thank you all for the feedback

@mfalkvidd hello!

I was referring to this statement in the site:

"Use this mode if you power the sensor with a battery. In this mode the sensor will sleep most of the time and only report the cumulative water volume."

Thank you

Any one used this approach? From the text I see that the node sleeps! How does it measures the consumption if the node is sleeping?

Thank you

Hello, sorry to bring this topic back from the grave, but did you managed to do this! I also have a use case for a raspberry pi zero w as node! Is this possible? And will I be able to react to a mysensors income message with a scrip in the pi? I want to send some tcp packages by wifi when a specific message arrives. If this is not possible I will need to make this kind of solution but with a esp8266, but since I have some pies already doing this job I would prefer to do with them! I want to bypass the need to have the controller online to this specific message!

Thank you

Yes it is! I use I'm using it as a MQTT gateway for some time

@tbowmo yeh I know that! The main purpose of this topic was to give out my thank you to all the community. I remembered the "subscription" (I didn't wanted to use this work because it sounds like obligation, and that is not what I intended... but I think that my English vocabulary is starting to fade out... ) because I had a active role one a community a long time ago and from my opinion it was always better to have a 10 users subscribing 1 dollar monthly, that 1 user donating 50 dollars randomly! Membership its always a way to bring people closer to the projects and helping out

I'm having difficult finding the IC4 ACS712_5A, if I search for "ACS712 5A" I only get the assembled unit. Can I get one of this and unsolder the IC and use it?

Thank you @David-Muller

Hello all, I'm using Nodered with a MQTT Gateway, and I'm planning on changing to a TCP Gateway, does the Mysensors node support TCP Gateway? I would like to remove MQTT from the mysensors equation to remove some complexity (on less service running and depending on), but On the Mysensors Node on NodeRed it seams that only supports MQTT!

Thank You
