Troubleshooting

Thanks, I got it working with the downgrade described in https://forum.mysensors.org/topic/4680/mysensors-2-0-ethernet-gateway-atmega-w5100-restart-all-time/9

Thanks, I tried this solution. The problem was described also in https://forum.mysensors.org/topic/4462/gatewayw5100-unable-to-get-working-w-v2-0-0/2 The "Arduino AVR Boards" 1.6.11 works fine, the 1.6.14 not.

I notice Wemos sells one which they claim can supply up to 300ma at 3.3v: https://www.aliexpress.com/store/product/WEMOS-CH340G-Breakout-5V-3-3V-USB-to-serial-module/1331105_32664922086.html?spm=2114.8147860.0.0.lHm5wW So far it's the only one I've found that can supply decent current at 3.3v. A lot of the alternatives can barely supply 50ma at 3.3v. 50ma is adequate for signalling, but often not enough for also powering a project.

@Yveaux and @mfalkvidd thanks! It's not important for me, just curious to know why :)

@mfalkvidd Thank you! The sketch on that thread should work :)

Thank you @scalz! That did the trick. Finally I can debug the code with readable serial feedback. Ok @AWI so the example code is probably in need for some adjustments. Its kinda hard for a beginner like myself to learn the basics if also the example code suffers from questionable functionality. Or perhaps the functionality is ok but the code by itself is not clear enough to educate the masses. I'm still having trouble understanding whats really happening when using the sleep() call. In my newest revision I'm not passing any interrupt conditions other than a time variable but still its obvious that the sleep is interrupted by the interrupt defined in the setup section. And as such, perhaps also some timer functionality is running while in a MySensors sleep. Perhaps the API description is in need for some additional clarification. Note: I've also deleted the attach and detach calls from the loop() section as this is probably handled by the sleep function (or other hidden code).

@jogant yes this is a common problem. The easiest solution is to have greater distance between the nodes.

Have similar issue while connect 1-wire sensors to pins 4 (power) and 5 (data) for low energy sensor. Looks like at least pin 5 used internally (as LED ?) by MySensors and broke 1-wire i/o. After moving 1-wire "data" pin to "A1" and hardwire "power" pin to "VCC" I have no issues with DS18B20. But about 3.5uA per sensor more in sleep (11-12uA instead of 4.7). BTW: still have issue with node registration and/or other connection issues - after approx. 2 days node whan't to send data to gateway... Will debug later. PS: MySensors v2.0 from Arduino Lib manager, Arduino Pro Mini 3.3V@8MHz@4.1VLiPo

This my script with decimals commandArray = {} if devicechanged['Panna_V'] or devicechanged['Huset_V'] then local panna_v = otherdevices_svalues["Panna_V"] local huset_v = otherdevices_svalues["Huset_V"] local hushall_kwh = uservariables['Hushåll_kWh'] local huset_kwh = uservariables['Huset_kWh'] local panna_kwh = uservariables['Panna_kWh'] local panna, energy, huset, energy2 --print(pan) --print(hus) _,_,panna, energy = string.find(panna_v, "(.+);(.+)") _,_,huset, energy2 = string.find(huset_v, "(.+);(.+)") --print(panna) --print(huset) --print(energy) --print ("energy2="..energy2) --print ("huset_kwh="..huset_kwh) husetdiff_kwh = energy2 - huset_kwh --print ("husetdiff kwh") --print (husetdiff_kwh) --print ("energy="..energy) --print ("panna_kwh="..panna_kwh) pannadiff_kwh = energy - panna_kwh --print ("pannadiff kwh") --print (pannadiff_kwh) hushal_kwh = husetdiff_kwh - pannadiff_kwh hushall_kwh = hushall_kwh + hushal_kwh --print ("hushåll_kwh") --print (hushall_kwh) panna = tonumber(panna) huset = tonumber(huset) hush = huset - panna ener = energy2 - energy --print(hush) --print(ener) if hush > 0 then --print(el) commandArray['Variable:Hushåll_kWh']= tostring(hushall_kwh) commandArray['Variable:Huset_kWh']= tostring(energy2) commandArray['Variable:Panna_kWh']= tostring(energy) abc = tostring(hush) def = tostring(hushall_kwh) commandArray['UpdateDevice'] = '272|0|'..abc..';'..def..'' else end end return commandArray I am using Dummy, Electric(Instant&Counter) version 3.5721 of DZ Panna_V(heating system) and Huset_V(whole house) is electric usage meters that report every 5 minute. I use my Dummy to show my electric consumption without(minus) my heating system

Ah, great hint! It seems like I have to change the high fuse to "Preserve EEPROM memory through the Chip Erase cycle" (see fuse calculator). I will try that out.

@tekka unbelievable !!! I tried with NRF24 and arduino nano, it's working like a charm !!! If I use the same sketch, on a pro mini using one of my ftdi as serial interface the Tx don't go threw anymore !!! Ftdi use a 1047 chip Arduino nano use a CH340 for which I had to install a Chinese driver for it !?!? !!!!

But now the Debug messages are still sent to serial monitor over the serial port which has to be changed to the SoftwareSerial port . Only the "SoftwareSerial.print " messages are sent to SoftwareSerial port . How can i change this configuration ( where ) ? => Variable MY_SERIALDEVICE in MyHwSAMD.h file ? #define MY_SERIALDEVICE SerialUSB Thank you

@finge, I hade the same issue and it took a while to find where all the librarys are stored. Anyhow, after a bit of digging I found them here: https://github.com/mysensors/MySensorsArduinoExamples Just add all stuff in the Library folder into your own Library folder and you should be good to go :) Also, don't miss that your gateway needs to be running 2.0 if your nodes does, otherwise it will not work either. Regards, Henrik

@DomoJimbo - great to hear!

@executivul. I've fond a solution in another thread that is implemented in the DEV branch. It is posted in another thread. I am sorry I don't have a link right now but I will post it later today. It's not really an optimal solution but a temporary fix until someone works something out. I'll get back to you with the link.

Hi ! I've same problem to make a node with 2 DS18B20 and 2 DHT22. In domoticz the DS18B20 sensors are show with humidity value (of the 1st DHT22) and the 2nd DHT22 show the humidity value of the 1st one... The sketch i'm using is here: https://forum.mysensors.org/topic/5222/node-with-ds18b20-and-dht22 (sorry for my bad english)

@emc2 Interesting read. @korttoma I've connected up IRQ line. Still no luck, @TON-RIJNAARD Have tried that now as well. No luck. Tried going back to basics and now have 2 x Arduino pros with RFM69 - both loaded with pingpong script. Don't know where I'm going wrong but I can't even start the script - entering 1 or T does nothing. (I"ve used the script before with the NRF radio and it works) Have also tried the latest dev version. Just keep getting this on both arduinos: 0 MCO:BGN:INIT NODE,CP=RRNNA--,VER=2.0.1-beta 4 TSM:INIT 1 MCO:BGN:INIT NODE,CP=RRNNA--,VER=2.0.1-beta 5 TSM:INIT 7 TSM:INIT:TSP OK 8 TSM:FPAR 138 TSF:MSG:SEND,255-255-255-255,s=255,c=3,t=7,pt=0,l=0,sg=0,ft=0,st=OK: 2145 !TSM:FPAR:NO REPLY 2147 TSM:FPAR 2277 TSF:MSG:SEND,255-255-255-255,s=255,c=3,t=7,pt=0,l=0,sg=0,ft=0,st=OK: 4284 !TSM:FPAR:NO REPLY 4286 TSM:FPAR 4416 TSF:MSG:SEND,255-255-255-255,s=255,c=3,t=7,pt=0,l=0,sg=0,ft=0,st=OK: 6423 !TSM:FPAR:NO REPLY 6425 TSM:FPAR 6555 TSF:MSG:SEND,255-255-255-255,s=255,c=3,t=7,pt=0,l=0,sg=0,ft=0,st=OK: 8562 !TSM:FPAR:FAIL 8563 TSM:FAIL:CNT=1 8565 TSM:FAIL:PDT
