    I usually use the MySensors Sensebender bootloader. It's 1.8V BOD and internal 8Mhz.
    else like nca78 said there is this topic:

      Thanks!
      I should have mentioned that I already set the BOD to 1.8V, but that doesn't help when the XTAL oscillator stops working at 2.6.
      I'll try one of those other bootloaders and see what flies.

        Okay I played around with this tonight and had some struggles. I couldn't get serial uploading working on any of the Gert Sanders bootloaders, so I had to use Arduino as ISP and Upload via Programmer.
        However since I have encryption enabled, I need the AES key in EEPROM before my nodes will work.
        So I had to enable the fuse that prevents EEPROM being erased when programming.

        I experimented with using the 1 MHz oscillator option, but the sketch didn't run properly. It was sending 5-8 copies of every message at a very slow rate.

        So now I'm trying the 8 MHz internal oscillator with BOD at 1.8 V to see if that works at a lower voltage than the crystal.

        If anyone knows if MySensors works at 1 MHz, or what might cause it to send multiple copies of the same message, speak up please!

          @Carywin I don't have any problem at 1MHz, all my battery nodes run perfectly at that frequency.
          But at 1MHz with internal oscillator the only speed you can safely use is 9600bauds.

            @scalz Can you please enlighten me re PIR? There are two inputs D6 and D7. I cannot understand why and how to manage them in a sketch? Previously, I only used one digital input.

              You need to use pinchange interrupts. I won't reinvent a howto, there are multiple on google, like the one from Gammon here
              https://gammon.com.au/forum/?id=11488&reply=6#reply6

              pinchange can only detect toggle. it's up to you to detect the pin state in the interrupt routine.
              Mysensors sleep() doesn't handle pinchange. so in this case, just use sleep(ms). and test for the irq flag when it wakes up

              In a previous post, I extracted and showed you the few functions needed for this. I thought it was enough documented!

              ISR (PCINT1_vect) 
              {
                if (digitalRead(AMBIANT_LIGHT_PIN)) 
                  irqLight = false;  
                else 
                  irqLight = true; 
              }  
              
              ISR (PCINT2_vect) 
              {
                if((PIND & (1 << PIND6)) == 0x40 ) {  
              	  myPirSensor.pirhCount++;  
              		myPirSensor.irqPir = true;  
              	}
                if((PIND & (1 << PIND7)) == 0x80 ) {  
              	  myPirSensor.pirlCount++;  
              		myPirSensor.irqPir = true;  
              	}

              So if we add this, in the MySensors Motion example, as a very basic example, this should look like this:

                Serial.println("Wake up!");  
              }
              

              Remember it detect pin change, so it will wake up at each pin change state.
              I can't make this example more noob and simple. then add all your variables for states, timers, improve power consumption etc, as you wish.

              Or, it's perhaps easier to use the example from carywinn above. he posted his sketch which use a lib to handle pinchange. (on my side I don't need a lib for this, and it also saves memory).

              I hope it's clear about pinchange, so I'm done at explaining it ;)

                }
                

                Remember it detect pin change, so it will wake up at each pin change state.
                I can't make this example more noob and simple. then add all your variables for states, timers, improve power consumption etc, as you wish.

                Or, it's perhaps easier to use the example from carywinn above. he posted his sketch which use a lib to handle pinchange. (on my side I don't need a lib for this, and it also saves memory).

                I hope it's clear about pinchange, so I'm done at explaining it ;)

                  Did anyone manage to find a good case for this sensor? Maybe 3D printed one?

                    I will gladly design a nice 3D printable case if someone can donate a board. I see that there are multiple battery options, so I would design a case that would fit all battery options.

                      @dbemowsk Thanks for volunteering!
                      I can probably order new boards (they come in batches of 3) from oshpark and send you one or two. They are 1.93 x 1.00 inch (49.0 x 25.4 mm).
                      Unfortunately, the boards I have with CR2450 battery holders and these are extremely fragile to be posted (they are soldered to little pads may come off easily).

                        @scalz I did just notice that I have about 30-32uA sleep consumption, which is too high. This is very consistent through 3 sensors. Any ideas why I have such high consumption? Obviously, there is a chance my multimeter is not giving me correct reading, but so far my Brymen BM869S has been very much spot on!

                          @alexsh1 looks weird, because there is nothing special on the board which could consumes like that, all parts are ultra low power..I tested mine with uCurrent gold device.
                          so I would say if it's consistent on 3sensors boards, it could be:

                          • software
                          • bad caps, out of specs parts..(I usually order my parts at Mouser, arrow etc..)

                          what do you get when using sketch J from gammon for example + shutdown sensors in case, no serial connected.

                            @scalz Sketch J is giving 1.5mA consumption.

                              so you get 1.5mA with sketch J but 35uA with your code ?? something is wrong..you may have forgotten to shutdown some peripherals.
                              with sketch J, you need to shutdown everything on your board in case peripherals are not well initialized. So that implies you include libs for radio etc in sketch J. Then disconnect your ftdi for power consumption tests. the PIR sensor itself won't consume more than 2-3uA, I tested it too.
                              On other side, sketch J is just a basic test, because almost same code is used in MySensors lib for sleep()

                              Sometimes I read people saying they have x uA power consumption for 328p standalone in deep sleep mode, but this is strange because here, on different 328p design, I have always been able to confirm the current consumption from the datasheet which is nA range. But I always used uCurrent..and reliable capa (X7R etc), hopefully I never got one capa extra leaking so far.
                              There is no magics, especially for this board, you should get what datasheets say..
                              When I made this board, I started by soldering only 328p circuit and checked power consumption, then tested step by step additional peripheral.

                                @scalz No, I copied and pasted sketch J so no radio peripherals included.
                                Strange that I have the same consumption on both boards - I think caps may be the reason! I'll try to desolder a few and test it again.

                                  where did you source your passive parts like capa, especially the bigger like 100uF ? (for curiosity)
                                  I guess you sourced others ic like opamp and comparator from a known source.

                                    @scalz different sources - arrow.com for opamp.
                                    For caps and resistors it is Aliexpress :))

                                      oki maybe try removing some of the big capa to see if it improves, use a simpler sketch where you just powerdown everything. there is no reason you don't get the low power consumption.
                                      regarding sketch J, yes, for sure you got 1.5ma because others peripherals were not initialized/shutdown

                                        @scalz I have desoldered all caps down to 1uF. Tried a different bootloader. However, I cannot get consumption down. I have opt3001 + atsha204a + AT25DF512C (all obtained from a good source). All resistor values are correct (resistor tolerance is 1%). Not sure what else I can do...

                                          @scalz I managed to narrow down the problem. Consumption (no radio attached) with Si7021 and opt3001 is 4.8uA, but with flash it goes up to 29uA while sleeping. This is a batch of AT25DF512C-MAHN-T I received from the US so quality is not an issue here. Seems to me that flash is not sleeping?

                                          My tests are showing that CJ2305 MOSFET consumption is negligible
