@GertSanders, dxf should be recognized now.

@GertSanders I can't know where you stand pricepoint wise, but this sounds like a 2 MCU project. One to handle the clock functions, and one to communicate with MySensors. Messages between the 2 MCU's over I2C. If the link is down, that will only clog the comms MCU.

@mfalkvidd said in is there a #define symbol for the first really free EEPROM address ?: https://github.com/mysensors/MySensors/issues/379 I would like to store some strings in eeprom. The nodes will also use the awesome simple security feature (signing, encryption). I suspect those also write some things to eeprom (I did research this just now, but I wasn't able to find anything on it). Combining all that: would it be smart to just start the storage of these string 'further down', like at 256? As far as I can tell all arduino's have at least 512bytes of eeprom, so then MySensors can still expand into the first 256 in the future, but my code will still be fine?

@gertsanders [SOLVED]: a wrong type in a declaration gave constant '0' values. Now corrected and distances is now measured correctly.

If you configure the controller to send notifications when nodes don't report anything after 1 or 2 hours, you know that something is wrong without draining the battery in the process.

@gertsanders said in Latest beta build of Domoticz (9379) crashes when adding new sensors: DIL connector I do not have a PCB. I have the atmega1284p board (Mightyduino) -> https://oshpark.com/shared_projects/zuZ4OIae and would like to have a moteino like board with either nrf24l01+ or rfm69 on it I can use wires to connect a transceiver but would like to have a neat solution

@GertSanders Hi. I'm not in front of my eagle stuff but you can extract it from this: https://learn.adafruit.com/adafruit-rfm69hcw-and-rfm96-rfm95-rfm98-lora-packet-padio-breakouts/downloads Side note: RFM95W and RFM69HCW shares the same footprint whereas RFM69HW has a different pinout. So for my long range nodes, i prefer RFM95W/69HCW footprint, more versatile imho As tbowmo said LORA is a spec. On my side i plan to use RFM95W for its features and longer range, in raw radio mode as we're using with mysensors. So it could offer more flexibility maybe, if i need repeaters etc.. I started something (a lib) a while ago but not finished, and now i'm trying to refactor rfm69 lib, then rfm95 if not already done. If you don't find your wish in the link above, i can send you/help you with some stuff i have done. I hope this helps, a bit

Nice build, and great idea using the ultra sonic sensor. This sort of thing was the exact reason I got into arduino and eventually mysensors. I had a concern about a damp basement and went looking for a water leak detection alarm but the prices were so high at the time... eventually I stumbled upon arduino and the obsession went from there. The first node I ever made was a water leak detection system that used the 4cm thing mentioned above... then I realized I had all these left over pins so I filled them up with a gas, flame, temperature, humidity and light sensor. Forget nest protect and commercial water leak detection systems... I now have an all in one DIY solution that probably only cost $30

@hek I would like to control the sending of this information just like sending sensor data. A "memory" sensor if you will. On Domoticz (or controller) side this needs to be possible. But I beleive this is already the case for Domoticz as I have logging of the cpu use and memory/storage use of the motherboard on which Domoticz runs (a Raspberry Pi 2 in my case). I will do some digging in Rob's code to find the datatypes used.

Not making too much headway with this. Chips arrived, soldered on the the reverse side of the easypcb. Not able to get any sign of the flash being seen. One odd thing, the physical solder pad for the flash chip, pin 6 on my boards isn't connected to sck of the arduino pin 13 at all, just a bare solder pad. I've bridged this with wire, still no luck. Hmmmm...! More experiments ahead, good fun!

@GertSanders No conclusive reading from the datasheet. I will do some measurements later. ..

I had some time yesterday to experiment with the Lowpower library and answered my own question. Conclusion: you can set the divider to a higher value then 10 (10 is used to test on permanent deep sleep by the Lowpower lib, and Mysensors lib as well I think), but it does not matter, the atmega328 ignores any value above 9, so 8 seconds is the longest deep sleep you can get. Oh well, worth a try.

@gertsanders you have good PCB design skills, great work but keep safety in mind, those cheap chines plastic box aren't for 220v and definitely not to houses any power supply.

I have five battery powered MySensors nodes powered with CR123 lithium batteries. I set the limits at 100% at 3.0v and 0% at 1.9v. Now I just need a method for Vera to generate an alert when they drop near 0%.

That simplifies my issue. I was trying (and now succeeded) to handle 160 char SMS messages (with DEBUG off), but the payload of S_INFO is the limiting factor. So now I can use a 30 char buffer AND keep DEBUG on, which is better for development. I will try to set up to git on dropbox, it is indeed transparent for my PC, not so sure about the Mac. And I still need to do the writeup for connecting the NRF24 directly to the Raspberry as a gateway

@drock1985 I know, RFM95 is even more expensive!

@GertSanders @LastSamurai Have you seen this thread: http://forum.mysensors.org/topic/1816/project-boxes-for-mysensor-s-nodes-and-gateway. Might be better to add to it rather than starting a new one. Cheers Al

@Iraklis-Kourtis Glad that you good it working and also replied that it's working for you
