@sundberg84 I do have a multimeter, but haven't used it in ages so I'm not sure how to honestly. =D

On the PCB I made all the connections by soldering but I have put that aside for now. Figure I must find out what I'm doing wrong with the radios first. Now when I'm trying to make a new serial gateway I've done so both with some soldering and some duponts.

Today, as a bit of a last restore, I'm gonna remove my radio from the ethernet gateway, which doesn't give me any failures in debug, and try the same setup with that. If that doesn't work, well..hehe.. Stuff is gonna break

I really appreciate all your help and suggestions guys!!

@royson84 the adafruit description says

connect the VIN pin to the 5V voltage pin

and

Vin: 3 to 5VDC

so I think any voltage between 3 and 5V will work.

Ok. Gonna give it a shot tomorrow with a Pro mini and see if that gives any different results.

Hi!
Hope it's ok to ask this here, didn't find a buy/sell thread.
I've got some Arduino Pro mini and NRF24L01 that I don't need. I just can't find the time making any projects with two small children bringing havok in the house
I also have a bunch of @sundberg84's EasyPCB for easy assembly of your sensors. It's been a real help for me when I got in to this.

Anyone interested? I'm in Sweden so it's a whole lot faster to order from me than from China

Best regards,
Hampus

Im sure this is a stupid question, but anyways. Im running 2.1 on my Ethernet gateway and sensors atm. Havent done any update since I first set it all up.
Now, if I update the gateway to 2.3, is it necessary to also update all the sensors? I saw on the download page that its recommended, but will the sensors work even if they run on 2.1?

Ok a bit of an update. I removed my "version" part from config...yaml. I then removed the mysensors.pickle file, restarted HA and then restarted my nodes. And voila, the started showing up. So either there was something wrong with the pickle-file or the version data didn't work.

But I can see now that the gw sends it's version to HA all the time, like a heartbeat. I'm not sure if this is correct or not.

Now I just need to figure out how to change the names of the sensors in HA to get them more like all my other devices.

There is the "discovery" option in configuration but I thinks that's more for gateways and bigger devices, not individual nodes. Not sure so I'll give it a try and activate it.
Other than adding the gw to my configuration, I haven't changed anything in my sketches, since that would be more work than I have time for at the moment.

Hi guys!
I recently switched from Domoticz to HA and I'm having some problems to get my Mysensors stuff working.
I can see that HA communicates with the ethernet gateway, and that my repeater gets "pinged". It also get some information from a Temp/Hum sensor. But none of this seems to get added to the UI. I can't find them in "states" either.

What am I doing wrong? Do I need to collect all my nodes and add something in the sketches? That would be a pain

@gohan I might just do that. Any seller to recommend?

It seems like the sensor might be broken. Tried it just now with the library from Sparkfun following this guide: https://learn.sparkfun.com/tutorials/bmp180-barometric-pressure-sensor-hookup-

BMP180 Init fail. The sensor is powered but that seems to be about it. Big disappointment.

@royson84 with that temp and pressure I would guess that you're in Hell I hope that's no the case.

How are you powering the BMP180? (where does 3.3V come from?)

Its now connected to an UNO that is powered from USB on my laptop. It get around 4V when a measure with multimeter. Might that be the problem? Will that destroy the poor little thing?

Can you test with a different Arduino?

Might have a Pro mini to give it a shot with.

Can you test with a different BMP180?

Nope, only bought one so far.

Do you get the exact same value for every reading, or do they vary (if you heat the sensor with your hand for example)?
Do you get the exact same value from the two libraries?

Same value from both libraries and sketches. And since the temp is 200C, I think I might have a difficult time getting another reading in my hand, but I'll give it a shot

So as the topic says, im having problems getting a working sketch to my BMP180. It shows some really weird readings:

Temperature = 200.30 *C
Pressure = 108908 Pa
Altitude = -613.66 meters
Pressure at sealevel (calculated) = 108914 Pa
Real altitude = -599.14 meters

I've tried the "sensorapi" sketch from "Adafruit BMP085 Unified" and the "BMP085test" från "Adafruit BMP085 Library".

Its connected like the guide says:
VIN<->3.3V
GND<->GND
SCL<->A5
SDA<->A4

My plan is to use this on a node together with a UV sensor and a DHT22.
Anyone how wants to take a shoot at what im doing wrong? Cause I suspect thats the case....

Thanks.
