ok thanks

yes, when I use de gw.sleep it works great but I can't go lower than 26ua+-. My test with your function draw 14ma because the nrf doesn't go to sleep... But is there a method to go lower than 26ua with the nrf? I'm already verry happy of the 26ua but if I can go lower, it would be even better ;D
Do you things it's because I use fake nrf? where can i bought real nrf? The one I use is from electrodragon.

I use the @funky81 's sleep method but the nrf doesn't go to sleep so I draw 14ma. When I use the gw.sleep method, I draw +-26ua. Is it possible to go below? (without the nrf, my own pcb with atmega328 go to 5ua in sleep mode with your function (doesn't work with gw.sleep because it's a test without the nrf ;D)

In your design, C3, the nrf 4u7 capacitor, is a classic ceramic capacitor. In the mysensors tutorial, they write a polarized capacitor is better for the NRF. I use tantalum capacitor wich are bigger but is there a difference with the ceramic one for the nrf. I would like to use a ceramic 0603 too if there is no difference for nrf.

Thank's

Ok, thank's! I've already change every A6 pin connection to A3. Can the user use A3 for analogic even if ATSHA204 is connected on it? or do I have to remove the A3 pin available for the user?

Ok, So I've to connect it on A3 (default value in mysensor?) and let the A7 floating? The A6 is not used so? (other question : I can't use digitalWrite on A6 pin?)

Thank's verry much for the details on ATSHA204A instead of ATSHA204. The ATSHA204A is in SOT23-3 too? so the A7 is only use inside the Atmega library?

hello, i'm making some mysensors board that I'll present you a bit later and I've add a place for the Atsha204 sot23-3.

I can't find it in Europe still and I would like to know if is it possible ton connect it on pin A6 instead of pin A3. I would like to keep the A0 to A5 for the user and use A6 for Atsha204 and A7 for Atcha204 floating point. Can anyone test it for me please?

Thank's verry much!

@axillent thanks for the values but what are the wattage of the resistors?

hox much current could you get with a LDO ort step-Down to 5V or 3.3V? 80ma?

with an access of your raspberry pi from anywhere (like "noip" I use), you can connect your android with jeedom and control it. It's what I do for my home automation (with a raspberry pi, a Jeedom server and a noip service)

And the jeedom's creator are working on an android special app too

For me, the easiest controller to install and run is Jeedom... Really easy to install : juste one command line, 1 password to type and 5minute to wait and that's it, you have a full domotic server on your raspberry pi with a amazing plugin store and a mysensor pluggin really easy to configure

Also update your sensors in 1.4.1 and update your MySensor plugin. It comes with a "new system" for Serial Gateway.

If you want more help about jeedom or mysensors on jeedom, please go to the jeedom's forum where there's a mysensor sub-forum with a lot of people and very active. (Even more active than this forum ;D) You can post in english, no problems!

ATSHA204

This module is verry interesting but how it work? What you have to do in code to make it work, crypting messages,...?

@BulldogLowell said:

if you need it to run on battery, then you may not want to bother with sleep, since you are looking for the non-occurrence of something.

the interrupt method will wake the MCU every time the led flashes...

you could start with code like this (untested):

why not use sleep. Yes it will wake the MCU every time the led flashes but it 'll consume less power when it sleep. you can go from 7ma to 10ua when it sleep. Even for one seconds it's a benefit no?

ok, I'll try that. Really looking forward to play with it ;D

OK, Thank's!

The GUI doesn't work on mac with wine. The program is running good but do not recognize the usb device (even with a symbolic link to wine,...). Is it possible to get the program on mac?

is it possible tu use the ota bootloader on 8Mhz?

It depend if it's in battery or not. If not on battery you can save de "millis()" of each turn on and if the curent millis()-lastTurnOn >5000 your led do not turn on since 5seconds. Of you can also add an interrupt on the photoresistor, save the millis, go to sleep with the interrupt and à timer. Each interrupt will update the current millis and if you don't have a interrupt for 5secinds, the sleep timer will wake the arduino and the same calcul to know that the millis don't change since 5seconds.

I don't know if it's clear ;D?

Yeah, really looks nice!
Can't wait too for the link and more info about de OTA bootloader.
I'm making some industrial opensources sensor based on MySensor and my current bootloader don't have an OTA Bootloader. So it would be greate with your Bootloader and your application!

I'vr git exactly the same probleme and I dolce it withe a step up 3,3v just for the PiR. I think the chip if the PIR really need 3v IR higher and below 3v it give false alert. You get exactly the same error by giving 3,3v to a 5v PiR with régulator.
