@kalina
Can we buy it preassembled soon?@Cliff-Karlsson Yes, i have made 10 pcs. But if necessary i can solder more. Price for model with RFM69 is 23$ and with NRF24L01 is 20$...

Ok, great. Are there any progress on the MDMSensor "Multisensor" and gateway?

@Cliff-Karlsson Yes, gateway is ready, but MDMSensor "Multisensor" is still in progress...

Hello
Why do you use a triac instead a relay for command the light ? What is the point ?

Hi @tonnerre33. MOC3043 triac includes the function of Zero Voltage Crossing, this mean that triac can trigger only when AC voltage close to 0 V. SSR doesn't use this feature. If you use just one device with ordinary relay or SSR, it is not appreciably, but if the number of switching devices increases and they all switch on at the moment of maximum value AC voltage, this will produce a lot of impulse spikes of voltage, which is not desirable. Ordinary relay also makes a not comfortable sound...

@kalina thx for your answer ;)

Hi, I want to share good news in the my project. Lighting has become more safer.
Instead the enclosure, I use a heat shrink tubing 3M MDT-A-32/7.5.
Here's result.

Your system works with phase and neutral wires? Will you make it compatible without neutral as well? In my house installation no neutral behind the wall switch only phase. And o the lamp side only neutral and the return wire from the wall switch.

Yes.

Actually, no. Why do you plan put this into the wall switch area? As for me, i am going to put "Lighting" near the lamp. Wall switch must be as a push button (normally closed). When you press button circuit opens (on short time) and Atmega328 resets and toggles lamp state. It means that "Lighting" always is conneted to the AC line. You can also change lamp state directly from your controller at any time. See picture below.

I didn't know this method ;)

Do we have a limite time for circuit open ?
Atmega328 resets and toggles lamp
How do you do this in the sketch ?
Where can we find the sketch ?
What are the consequences for the components life ?With this use, the reboot time will impact the response time bewtween the command and the lamp power , isn't it ?

Yes, of course. In my opinion, this time we can determine in practice, i don't know how can it be calculated. I haven't done it yet, I will try to do it on weekend.

With this use, the reboot time will impact the response time bewtween the command and the lamp power , isn't it ?I have no answers on this questions, it is certainly disadvantages of this method, but i wont use wall switch very often, i prefer to operate via controller. No need reboot uC in this case.

@kalina : your solution is quite interesting when push button are installed. Yes, i would like to put the system in the wall switch. For the moment, i connect the switch of the house on the arduino. The system is powered by phase and neutral in the garage as behind the switch i had the neutral wire. However, in the house no neutral like on your picture. So, im checking about using leakage current which should be enough to power on the system.... Not sure.

I would be interested to hear about your results
-
@Kalina, does your project still alive? do you still have some samples for sales ?
@jeremushka This project has some shortcomings. For this reason I have released a new, more advanced version - MDMSNode "Lighting" Rev 1.1. If you are interested, I have more than 10 pcs in stock.
