Hello,

I am reviving this as I upgraded my kernel to 7.0 and now have communications issues.

I discovered that I had to force port speed when opening it up to the right speed, then it communicates a bit then nothing...

driver is ch341

any idea ?

as I experienced, MQ sensors are not really gaz sensitive, they are more particle size sensitive when hot enough and when not totally scrap.

I would not rely my life on them, if you have an alcool spray use it around and any MQ will to go the sky...

intermediary result: I have started a second gateway and now the nodes do communicate... puzzled...

I remove the extra gateway... same situation...

so reprogram gateway with:
#define MY_RF24_PA_LEVEL RF24_PA_LOW

so it seems this was the responsible for this !

thanks !

will try to put it in debug mode. now I've added a 1u and 100u with no result

Hello,

Today I migrated my gateway from 1.5.1 to 2.3.2, tested it fine.

Then I started trying to reprogram my sensors to 2.3.2 and none works. No wiring changed, previously fine working (CO2, DSM dust sensor)

Hy there, added an AMS1117 regulator board and a 4,7uF and this works agains ! thanks all for your help !

Hello,

my box:
https://photos.app.goo.gl/MQijz9SK8wBMnic47

can AMS1117 be enough or not powerful enough (I have some).

Not US sadly, but amazon has more stock than local providers as it seems, thanks for the hint !

Hello,

I have a basic arduino pro micro and the 3.3V is from the board. All is directly wired on it (arduino to ebyte module with antenna)

I suspect maybe that the 5V may not be that powerfull, I will enquire (I modified something recently...not sure anymore). Usually it is from phone charger. I've seen I have not changed the gain in the radio too, same code for a long time, my whole network is still in 1.6

I've searched for the ld1117d33 (retired) or its clone, seems difficult to find.

Hello,

I have a water counter that requires a value from the gateway.

So the request is received but the answer is never received as it seems.

Both are with a 5V 1A power generator, toward the arduino mini pro, then the 3.3V directly to the module.

I've looked at the datasheet, I've seen nothing about a capacitor ?

Hi All,

I wanted to use Ebyte nRF24L01P Wireless rf Transceiver E01-2G4M27D 27dBm SPI 2.4GHz with a bif antenna: TX2400-JKD-20 3.0dBi Flexible 2.4GHz RF

But it seems an emission issue on the gateway side where I did put it.

It is directly wired to the arduino.

Any idea ?

maybe check what they did here:
https://github.com/airgradienthq/arduino/blob/master/AirGradient.cpp

thanks for this survey !:

it you remove plastic it is not water proof anymore, and greyscale was not precise enough....
CNY70 has reflexion protection which is much better

not with mysensors, but could have been: CNY70 water sensor meter (rotating wheel) with extended wifi range, the heart of it is a Particle Photon pushing to domoticz

here is a link with the schematics (so simple !):https://easydomoticz.com/forum/viewtopic.php?f=17&t=1737&start=70

Hello,

I've dropped this approch to use the CNY70 ir on this water meter.

I did that for a friend that has not the mysensors gateway (range issue) so I made it with a Particle Photon using a wifi extender, but it is quite straightforward reading the pulse up and down.

MQ are always a bad choice, saturate air around with any gas and they will react ...

Mics are used by sensely, but even them aren ot calibrated... and they are a hell to get working even when you have the pins soldered to them.

@lukács-attila check wiring first, seems there are several sub version around thay may need other values from datasheet

@ambuj please see the begining of the discussion regarding MQ like reliability

@gohan I would have too much work going to 2.0 on every node I have, but I have to do this as a background task since I'll have to upgrade all my sketches first...

swapping hardware is an option, recabling everything is not my cup of tea ;-)
