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.

Hello,
This module is finally available to buy assembled. Now our project is complete, you can run the whole RS485 system after some shopping here, on openhardware.io. See details on the project pages.

Cheers,

Actually I have to disagree with @rejoe2 about:

Will my network work without controller (only gateway + nodes)?

With an Ethernet gateway it is entirely possible.

One more thing. If you are interested in building RS485 network, maybe you should have a look at my project. Earlier today I created a post about it on this forum. Here it is

@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.

Hi all,
We are still working hard on our project of MySensors&RS485 based, wired home automation system. Right now we are preparing a crowdfunding campaign aimed to deliver some of our designs to backers. We’ve received some official MySensors community support and our RS845 Ethernet Gateway project is now featured.

If anyone is interested in supporting our effort, please subscribe for campaign updates. Telling about us to others would be even better. We need a lot of support to succeed.

I will happily answer any questions. Link to the campaign pre-launch page:

I have similar problem. Some time ago I even wrote a nice piece of code to update roller shutter position if changed from buttons. But domoticz just does not seem to understand values the sensor sends. So I confirm, blinds percentage is buggy.

Star topology is not recommended to use with RS485, but it is not that it certainly won't work. You have to test it.

When it comes to experience, I have one with much more than 5 modules. It works pretty good, even if the modules are badly designed. To achieve top reliability though, you have to use well designed modules.

If you are thinking about RS485 system, have a look at my hardware:

If you like it, please feel free to contact me. We've made some significant progress, which is not published yet.

This project is impressive, I really like it. Pity it is so silent about it. After all this work, are you not willing to finish it?
