@anticimex @Encrypt That's a bit odd and certainly specific to the bootloader you're using (ATmegaBoot): AVRdude does (at least with optiboot) a page erase (vs. chip erase where EESAVE has an effect). I do not have the EESAVE fuse bit set and no issues with erased eeprom when loading a new sketch, also see below:

Arduino Uno with optiboot:

uno.bootloader.tool=avrdude
uno.bootloader.low_fuses=0xFF
uno.bootloader.high_fuses=0xDE
uno.bootloader.extended_fuses=0xFD
uno.bootloader.unlock_bits=0x3F
uno.bootloader.lock_bits=0x0F
uno.bootloader.file=optiboot/optiboot_atmega328.hex

High fuse (0xDE) does not enable EESAVE.

@skywatch Take a look at my pan tilt project. A stepper i.s.o. servo can easily be achieved. I would recommend to use the AccelStepper lib to have a smooth movement.

@zboblamont said in SensorDoor + Backup Send:

would this not report either correct state short of inhuman speed?

I guess it would, but there's always the chance of missing a message, so a regular status update could help there.

@fernando-alvarez-buylla the link (created with the ln command) will be removed at reboot. Change my-serial-pty=/dev/ttyMySensorsGateway to my-serial-pty=/dev/ttyUSB020 and re-run all the commands.

If you don't reboot the pi after enabling the mysgw service, you will need to start the gateway as per the instructions printed when make is finished.

@nalith See the sleeping section in the API description.
The sleep function takes one or two interrupts to wake up the node on triggering, and an optional ms parameter that defines the amount of milleseconds to sleep before waking up anyway.
The return code of the sleep function indicates what woke the node, e.g. (untested!):

#define PIN_DOORALARM          (2)            // only 2 & 3 are supported on ATMega328!
#define SLEEP_TIME_MS          (60*1000)      // sleep 60.000 milliseconds -> 60 seconds
#define DEBOUNCE_TIME_MS       (15)

void setup ()
{
    pinMode(PIN_DOORALARM,  INPUT_PULLUP);
}

void loop()
{
    // ... do whatever you like ...

    // Sleep until node wakes up by interrupt or timeout
    uint8_t result = sleep( digitalPinToInterrupt(PIN_DOORALARM), FALLING, SLEEP_TIME_MS );
    if ( MY_WAKE_UP_BY_TIMER  == result )
    {
        // woke by timer -> e.g. send current status
    }    
    else if ( digitalPinToInterrupt(PIN_DOORALARM) == result )
    {
        // woke by interrupt -> send current status / raise alarm

        // debounce might be required; depending on your switches
        delay(DEBOUNCE_MS);
    }    
}

@encrypt yes they look good

Nice work @encrypt

Does the gateway startup CP=... line match the settings for the node?

New gateway going live and migrating slowly from Domoticz to Homeassistant. At least to try it.

@bgunnarb there is no way for the rpi gw to affect your ability to use ssh, so the problem is probably on the network or OS level.
Does dmesg or syslog say anything around the times when the problem occurs?

@pepson you’re missing a } before start of loop.
