@nca78 about my gateways: an old gateway running on MySensors 1.5 for years now. There are several nodes and sensors connected through it like temperature sensors, relays, switches. It controls my heating system with heat pump, buffering, 18 circles of floor heating, garden irrigation, alarm system, and some lights just for fun. the new gateway is a gateway to a Bluetooth network. Since MySensors has a great serial API and I have some experience with it I preferred to use it without a radio. I also think that it will be an interesting way of development and it could help to make MySensors even more popular. I had an idea to fork the library but unfortunately I don't have the experience and time to make it in good quality. But I'm sure letting developers to build connectors to different protocols is a very good idea. Catching Bluetooth messages from the air and decode them (with some reverse engineering) to send it through the MySensors gateway is relatively simple compared to the bidirectional communications. Processing some simple sensor data is a good first step.

Please Is it possible to buy only PCB? Do you plan also to release your sketch?

Update on the project. New version added to openhardware.io

@nca78 I don't use ATAES132A. I put it in just in case I wanted to invest some more time using it. I now just use SimpleEncryption, it's secure enough for my purpose atm. (since the area I live in uses KAKU a lot, an insecure 433MHz lightswitch, I don't think anyone would be bothered to hack my temperature sensors. I found 163 433Mhz devices when I left domoticz logging for a couple of days.)

@mr_red I have a zipped snapshot of all the 3d step/wrl models that I used to build my projects so far. It was quite some work to gather them all and align with the footprints using the kicad stepup tools. It's not complete - still needs some more work:simple_smile: but it should help you or anyone else to get started into MCAD integration using FreeCAD and kicad stepup tools. Maybe it's not very easy to start when using free tools but hey they are "FREE" so we cannot ask for more. But the nice thing is that once you get used it will be really easy to do your stuff and to go forward. Oh and FreeCAD can be so powerful after you learn it - I was really amazed what you can do with it(it has it's quirks and downsides but once you master it - oh, well...). There's also: https://www.onshape.com/ - pretty powerful this one too and it has more advanced features than FreeCAD but the downside is that it's a cloud based solution: it's free for public documents but you never know when they will go to paid accounts only so yeah...I don't really like the idea to depend on something that it's hosted and the application is not on my PC along with the documents that I create with it. Cloud solutions have their flexibility but you're locked and you depend entirely on that hosted service. Ok, enough talking...I uploaded the zip file here: http://www.mediafire.com/file/kzh1l9uo40cpj1u/kicad_stepup_packages.zip

Hello. Any news from this project? Do you made the changes for the timer TLP?

I am still using several temp/hum sensor and they are running great I also have just added code and pictures for my newly build light sensor (using an LDR).
