Still having problems and this is my first purchase from PCBway not sure if the code need to be changed for this board but I am using PCB MySensors Gateway Ethernet 3.0 developed by fifisoft57. The radios work on other projects and it is almost like the pins are not correct I traced them and they appear right but......... Has anyone used this board if so did you have any issues? I would say it is my solder job but I did 3 boards one should work.
ANy help would be great.
my experience is different, aliexpress is collected vat on purchase and item was shipped from Netherlands
VAT (collected by Aliexpress): 2.59€
my post office sent me email asking for pay 6.09€ (2.59vat and 3.50 fee) and there is no way of contacting them or sending pre-paid vat just a reference number to pay vat online.
Please note that below is just my simple view on sensors of any type.
I think any sensor exposed to environment will need some type or form of maintenance/cleaning or replacement. I also do not think that sensor can test itself unless there is other sensor of different type/technology monitoring other sensor.
As you mentioned previously true way to test sensors is using smoke can from time to time as dust particles/moisture/grease may affect sensors of different types.
I think you need to post a clear drawing or photos of the setup and the code you are using.
I donlt know what you mean by "connecting the current in series" nor what "AC regulator" you are using or what "thermal serial currenr" is.
One little project and you're hooked! You know you're going to want another sensor in the yard, so consider a gateway running MQTT (called a broker). Once you have that, it's really easy to add more sensors.
But if you're really strong willed an will only be using two devices ever, you might look at https://nrf24.github.io/RF24/index.html. You can get an Arduino Nano and an nRF24 radio for about $3.50 from Aliexpress (downside: delivery takes ~2 months, so get 10 each.)
MySensors Library can do this, too, but I find it a little bloated.
Personal note: I'm 70, retired engineer, and have only four projects going right now.
