GetWired – RS485 & MySensors home automation modules

feanor-anglin last edited by feanor-anglin

Hello Everyone!
As some of you may know, me and my friend @slawkiwala are working on a project of a wired home automation system based on RS485 and MySensors. From the beginning we were quite serious about it and now we managed to launch a crowdfunding campaign.

Though probably the majority of you here are interested more in wireless hardware than in wired, maybe our project will be useful for at least some of the members of this community. If so, then please support and share our campaign!

More info can be found on the campaign page

PS First revisions of the designs, which are now taking part in the campaign, were published on openhardware.io.

PS2 Important information about shipping: Crowd Supply pre-clears customs and pre-pais VAT for packages shipped to all EU countries, Switzerland, Australia, and Canada. This means backers from these countries will not have to pay anything more than the pledge level cost + the international surcharge and also will not have to pass any customs control.

@kimot No, it is an obvious mistake, I am very sorry. Maybe it is becouse the code in master branch is very old, the newest is not yet on github, but the developement branch is quite new. I am going to fix this soon.

@openhardware-io Hi: (Please direct to Feanor-Anglin if possible) I previously ordered some 4RelayDIN PCBs off openhardware.io and got v1.6 PCBs but the info on the site I found is only for an earlier version of the PCB board. I am trying to build some of the boards but there are additional compomemts on the newer PCB board. The main one which looks to be a driver IC. Would you please share the updated information with me or perhaps update the openhardware.io site. Many thanks, Rod

I found this old thread and since I have a Vallox machine it's interesting. RS485 is new to me but MySensors isn't. Can I have a node like this described by Heinz parallel with the "mickey mouse"-display? Using the display's connector? Or is it one or the other? I'd feel better having both (manual display&buttons and connection to MySensors=>Domoticz, in my case).

@blebbens It's been a while. But if I remeber it correctly you have to set #define SOFTSPI in MyConfig.h too. Don't forget to comment it back when you're compiling a sketch for a node. My router uses DHCP as well. But I can assign a static IP in the sketch. Shouldn't be a problem. I'm not sure, but I think the arduino can't handle DHCP, it's a really simple ethernet card. So you need to assign an IP in the sketch.

@Boots33 Thanks a lot for the quick response. I now have my Nano running as a serial gateway and it is connected via a USB cable directly to my controller (Raspberry Pi 4 running Home Assistant / Hass.io). I added a local motion sensor to the Nano gateway HW and pasted the mysensors MotionSensor example code to the setup(), presentation() and loop() functions as well as to the definitions in the top of the GatewaySerial example code. I disabled the radio definitions as I currently have no radio capability in my gateway (not sure if this was necessary). In Home Assistant / Hass.io I updated the configuration.yaml with the following text (as described on the Home Assistant integration help): mysensors: gateways: - device: '/dev/ttyUSB0' And it works In Home Assistant Developer Tools under States I can now see my motion sensor go on and off by the flick of my hand. I had expected a bit more bumps on the road just to get this far, but wow - I am obviously walking in the foot prints of people who have worked hard to make it easy for the rest of us. I am sure I will hit bumps on the way when the radios have to send results to the gateway (thick concrete walls with lots of steel), but for now I will enjoy this big success. Thanks again Boots33

This is great, thanks! One suggestion: add a switch mode regulator that can handle 12 or 24 volt DC input. This will allow small sensor devices to hang off a typical bus network having extra pairs for the central power supply.
