General Discussion

Thank you for the idea. I try and I will do a report. But is there a way to start the sketch after a delay even if the gateway does not find the broker. I understand that this is not very interesting .... except for my library. With a node, it is possible to start the sketch after a delay with the parameter MY_TRANSPORT_WAIT_READY_MS. Thank you.

@mfalkvidd Unfortunately, the "Enable In-Topic Searching" feature is what generates the start of "in:topic-4803 soft_hmac_key" and nothing else. It does find the first occurrence but doesn't have a way to search after the first. I learned that I can just prefix "in:topic-####" to my search and then I don't have to make the forum grab the <ctrl> f key in my browser. @the person who edited the "Posts per Page" restriction of 20, a huge giant Thank You!! 100 posts per page is a great improvement over 20. I was about to request this but saw it was done when I went to get the exact wording. :-) This giant topic being 10 pages is bearable. (and probably doesn't use a ton of javascript which was blocking local caching so probably saves a ton of bandwidth for your servers...) P.S. my original problem is solved too, the forum is so useful!

@alexsh1 Much the same principal as my 5v/3v solution for the 5v ultrasonic, only here I used a latching relay leaving the 3v Arduino on sleep power consumption. An interesting device however, with a low standby and effectively a timer function, it has many possibilities. Where this original project has been skewed is unfortunate, the selected devices compel the dual voltage solution, whereas an alternative strategy removes the need for it completely. Although pulses and switches can be regarded as "old" technology, they can still be highly effective for battery powered applications where energy conservation is critical..

Nice! :) https://lowpowerlab.com/2018/07/07/new-products-m0-breakout-boards/

Hi @raulp, welcome to the MySensors community. I don't understand what you are trying to do, but the MySensors getting started guide is available from the rocket icon at the top of the forum (https://www.mysensors.org/about ) Developer contribution guidelines are available at https://www.mysensors.org/download/contributing Library documentation is available at https://www.mysensors.org/apidocs/index.html

@dbemowsk I used LP2950-5.0 in one node when feeding from 12v - about 3 months everything works quite stably.

Arduino IDE can only program chip, not read its program memory. But you can use AVRDUDE ( maybe with some GUI ) for reading program memory from your chip. And in your program sketch define some string to identify version. It can be read hex output of program memory then.

Trying it with the extra config command: --extra-cxxflags="-DMY_OTA_LOG_RECEIVER_FEATURE"

Great work @eric007, thanks for reporting back!

@eric007 I think I found by myself: using events to manage my installation.

Nevermind i fixed it! had something to do with my radio... Driving me nuts :-) #lovemysensors!! can close this topic when needed

@nca78 I start experiment this weekend and will give it a try. Thanks for the ideas to make a working solution, in this case the use of an existing IR controle.

@nca78 said in Combining orders at OpenHardware.io?: Just make a paypal donation of the PCB price difference to MySensors for that. Maker of PCB will lose their share but it's pretty small and it ends up given as donation to MySensors most of the time. Excellent idea!

Thanks, I'll try it!

@gohan Disabled my Firewall and Virusscanner and now it seems to work :)

@gohan Nope, hourly measurement is quite sufficient. I had bought two of these with onboard RTC to pass time control to the DS3231M and let the Nodes sleep, at the time it was purportedly energy advantageous. I'm aware I could have used a non-RTC version and a sleep time, although have yet to succesfully make sleep for an hour for some reason, yet 30 minutes is no problem. Just puzzled how it should be deployed, hence the query..

Thought I'd share a couple cool things I've learned recently. One is that meshmixer offers treelike supports, which is pretty cool, and it's free: [image: mainpage_download.png] You can import your model and just add the supports without using the rest of meshmixer, if that's all you want. That's how I plan to use it. The other is that if you want to print faster, but with good print quality, you should definitely look into linear advance. https://www.youtube.com/watch?v=c5jjwBqARpo&t=255s Anyone else learned anything cool lately?

You can use this category (general discussion) if you like. Or try the openhardware category, if it is open to new threads. It is open to me, but that might be because I have admin privileges.

@zboblamont After a lot of headscratching I solved part of this puzzle and feeling a little stupid. Nothing to do with Library conflicts, both Wire and softwareSerial work as they are supposed to, the level converter works perfectly, it was a combination of sketch issues and the manner in which sleep was invoked on both Master and Slave, as well as a problem ultrasonic board. 1 - The DYP-ME007Y I could only ever get to read on a Russian developed sketch using softwareSerial. Although I got the reading once, the Slave was locked in an endless loop in the background, never going to sleep or giving the battery reading. By doing the ADC battery measurement first at least I got both readings, but with the Slave running endlessly even with the ultrasonic board shut down, it was killing the batteries. So I gave up on that one and switched to the second tank which uses time of flight calculation, readily incorporated as a function. This time I incorporated LED flashes so I could see what WAS and was NOT happening. 2 - The JSN-SR04T-2.0 Slave went to almost immediately per Gammon's sleeping Slave routine, would waken when prodded, but would not return a battery reading. The problem lay in Gammon's preparations prior to sleeping the Slave, where he turns off the ADC, but it remained off when awake. Commenting out the ADC shutdown at least solved that issue for now, at least the Slave gave the required readings and went to sleep, but... it never started again. 3 - The Master was going to sleep but never wakened on the onboard RTC alarm set to Int1. Switching to a straight Sleep period did not work either, until it finally it dawned that the Wire service may be interfering. Only when Wire was shut down and re-invoked after wakeup did both Master and Slave sleep and awaken as intended. Left it running overnight, and it has been consistently reporting every 30 minutes, so will look again today at getting the DS3231M to work properly on the Master and read how to restart the ADC on the Slave. Frustrating as a relative amateur, but lessons learned. If there is no function to interrogate the DYP ultrasonic, may just order another device from China and hope it proves simpler, cheap enough even if it takes a month...
