Sensebender Gateway:
@magpern
But get this board to Arduino IDE?
Boards / Boards manager...
search for sensebender
You might have to
File / Preferences / Additional Board manager URLs
add

[SOLVED]
After a one-on-one with @tekka we found that the problem was a very simple one.
The default channel 76 was noisy. I change channel to 90 and the Gateway and device could talk two-way communication
I did a WIFI scan an see that wifi 2.4g channel 11 is used by someone close to me (I am channel 2)
Wifi Channel 11 is almost in the mid of channel 76 (nRF24)
@pepson said in [SOLVED] Sensbender Gateway gives a lot of "hu":
Please help me what i do wrong...and how resolved this problem.
It is the exact same problem as I had. Do what @tekka said. Either put in the code he suggested, or git clone the development branch. The development branch works fine, the "hu" will go away
And if git clone is to difficult. Download the dev branch github as zip, unzip it and replace the entire "MySensors" folder on your computer. Exactly where it is, I don't know. It's in the library folder where Arduino is installed
@berkseo Seriously!!!!!!!!!!!!! It cannot be true!!! I have just ordered PCBs and all needed stuff to assemble it, and now the code is gone!!! Please post the code again, or make it available on alternative sites.. please. It is hundreds of dollars to waste otherwise!
@mfalkvidd Thank you for you detailed reply. The question actually arose spontaneously. I said to my wife.. I know what I want as a present, a new better multimeter. Then she saw me write here, and started asking questions about what forum I wrote in (= she will look here to find the answer and buy it for me)
But, as you state.. what do I need it for? Measuring some kind of micro current is one thought. And measuring capacitors.
Will my current one work for me, most likely, it has for many years and 95% of the time it is to look for shorts. Do I need a new one..no.
I looked in your thread about the multimeters and I think the VC99 seams to be a good one. Price of 28 USD is very good too.
I'll look into the uCurrent too, that looks cool!
@tekka Thanks! Development branch worked
Edit: After I posted this the device has worked for 2 days. But still, the capasitors are they correct?
@berkseo I have a wierd problem with the SHT20 sensor. It stops working after a few reads. Then the device hangs and goes into battery draining mode with atleast 8mA constant current. I have localized it to the SHT20, because if I comment out the init and read temp/humidity of the SHT20 the device boots up.
The wierdest is that the SHT20 stops responding for quite some time, even if I power cycle the device, it is still not responding.
Last night I had it running for 1 hour, powered with 3.3V directly. Turned power of, had some sleep, turned power on SHT20 not responding. Turned power of, played with the kids, 3 hours later turned power on, the SHT20 is now responding. Now it's been going for 20 minutes and is still responding. But I bet if I let it run, it will stop.
I am fairly sure the SHT20 is soldered to the board correctly. I used reflow (heatgun) and solder paste was liquid and I could poke the SHT20 and it popped back automatically by surface tension.
I have also tried to replace the SHT20, but the result is the same. the device when hung)
Anything you recognize?
I have not yet successfully been able to debug the device, if i compile with the MY_DEBUG active, the device does not come on and the led shines constantly and I'm not sure how to connect the FTDI, should Vcc on the SWD provide power or not?
I have checked the capasitors C12, C13 and C14 since they have been talked about before and differ from the BOM list and the real board.
C12 is 10uF
C13 is 100uF (100uF is very big, only had a 1206 size, but I got it in place, will get 47uF 0805 for next iteration, waiting for a solder paste dispenser from China)
C14 is 100nF
@mfalkvidd said in What multimeter should i wish for?:
@magpern totally agree. Myplan is to work through this playlist so I learn how to use mine. https://www.youtube.com/playlist?list=PLwOVNTOStjiCmxCFX91MZYP7wL8dfy1tB
Today Iearned to save screen shots and csv files to a usb stick. No snow, but lots of rain today
Nice.. "a snowy day" is more realistic then a "rainy day", but I guess, a snowy day means playing with the kids in the snow.. rain they don't care for.. so I guess "a rainy day" is more realistic after all.
It was indeed a rainy day, so I got 3 of my sonoff up and running with mqtt and domoticz. Next is to try with home assistant. Still waiting for some aliexpress stuff to continue with my MySensors devices, but I guess that will be "some snowy day"
