and perhaps some parts of this howto can help you too. not the same bootloader but I use usbasp. Yes you need to use your icsp conenctor or the spi port + rst pins if you want. https://forum.mysensors.org/topic/3503/sensebender-dualoptiboot-ota-howto-in-mysensors/18

This has been solved! Hi @stoffej! Can you please try to assist me on a very similar topic? I've built the EnergyMeterPulseSensor.ino pulse count sensor from the 2.0 library but I'm unable to initialize the items and I'm quite certain that this is why I'm not getting any values into Openhab. The Arduino is waiting for a request to be acknowledged which I guess is not happening. I have enabled persistence for the pulse counter items and I've also tried to initialize the items by manually sending a value through the openhab console (telnet localhost 5555). After updating the values manually I can see the new value in the sitemap-GUI but the actual counting does not start. After restarting Openhab the following is shown in the log: ... - New Item "myPCVar (Type=NumberItem, state=Uninitialized) based on configuration "50;1;V_VAR1" A funny thing is that I actually got it working while working on the pulse counter on an experimental setup without actually trying to initialize the items. I don't know what I did at that time or if it started working just by chance. Do you have any ideas of what steps to try? Thanks! Ah forget what I wrote. Its working now. I guess it was a poor radio module which seems to be the reason in a lot of cases.

Yep, absolute maximum is 15V. http://www.advanced-monolithic.com/pdf/ds1117.pdf
