@Fabien: Thanks!

I'm very interested by your setup. It has been a shame to have some low voltage power in order to measure power consumption :) I hope you can display something soon. Regards, Qq.

I think I found the problem. I think it misbehaved because of an illegal character in the "HOSTNAME". Changed the hostname yesterday and It was still alive this morning even if I have not pinged it.

Wow, what a bunch of useful information. I'm really happy of being part of this community. Many thanks to you guys. I've read the topics and also took a look in the @sundberg84 project. Now I'm thinking about make some changes to increase the safety, such as fuses (SSR, termal and normal one to protect against overcurrent) and varistor (to protect agains overvoltage). I already made some changes and also will order a PCB tomorrow. Feeling very optimistic!!

Hi @mr_red, thanks for posting. I already had change this, your advice was nice for me. Safety First! haha.

The project does not work without neutral wire

@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

Not yet ! In fact, the interrupt must be short enough and fast enough to be sure to not miss the RFM69 interrupts. The code for 8 dimmers will not be really more complicated : in fact, each time we got a zero cross, we must set a timer to zero, and then wait the good amount of milliseconds to turn on the needed outputs. So, yes, we'll have an interrupts each 10ms (each time the wave crosses the zero, to be precise !), but I think all we have to do in the interrupt handler is set the timer to zero (or to micros() ...) and then on the main loop, wait the good amount of time for each output before setting them ON. Seems simple on paper, perhaps it will not work on the chip.... In facts, my main concern is : will the RFM interrupt be short enough to not disturb the zero crossing interrupt ? Although, not yet tested the RFM : do we NEED the interrupt pin ? Can't we poll frequently the RFM?

I see a lot of "!TSF" and "NACK" which seems to be radio communication problems. That's MySensors related and can be related to many things, from soldering problem to power / capacitor issues. In MY_DEBUG mode you should see your temp/hum printed on serial every ~15s so there is something wrong there, either wiring or a code issue. Ty with the example included with the library "i2c_SI7021.h", without any MySensors related stuff, to see if your sensor is detected. You should see temp/hum on the serial.

@NeverDie said: Can it be programmed through the Arduino IDE? I had briefly looked into it back in 2011 and was able to get an Arduino sketch for blinking a LED to work. I had to upload it using the external dfu program since at the time the Arduino IDE did not allow specifying an external programmer device. I'm not familiar with what may currently be possible with the Arduino IDE since that time however. Plain C using gcc and uploading using dfu-programmer works fine though.

@MiKa which box are you referring to? Generic boxes are available here: https://www.mysensors.org/store/boxes
