Recently we had a Hackathon event at our office and where we showcase open source MySensors wireless network capability along with pimatic controller running on sweet pi.

@NotYetRated Hope you'll find good uses and a fun time while building your sensors.

@OldSurferDude yes, you are correct. this sensor is capable of 50A continuous, which safely I would make it working at 40A max., but for such an important load as in your case I would go for a beefier one, like the ACS75x, 77x, but at this point I would also change the node's form factor for space and insulation reasons. On my application on the RV I have a max. curr. of 13A running on a AWG14-16 cable (European rules for RVs), so I did not ask myself too many questions beside, of course, safety. About the signal, it will be a sinusoidal signal swinging around Vcc/2. Vcc can be easily measured internally on the ATmega328. On all my DC sensors I measure Vcc at every loop, just before measuring the ADCs. Honestly, when the space is not an issue like in my RV, I would rather use a ring core current transformer, and I would get rid of noise, response time, power dissipation, but over all no need to cut any cable. Long story short, it has been a nice experiment and I used it for 6 months, and then I switched back to my RF-NANO based RS485-Modbus - Mysensors bridge connected to an off-the shelf power analyzer. Just for fun I attach a pic of my 12Vdc sensors installed on my RV. Forgive me for the spaghetti wiring on the right side, but this is an area that needs improvement.

@OldSurferDude yeah, 10 virgin nodes powered up at the same time is a bad idea I seem to remember reading somwewhere here warning aginst that. If yu have node ID trust issues with Mysensors you should move your address to different locaion as 0x00 is used by Mysensors... just sayin..;)

Hallo! Ich habe gerade meinen Aduino Nano mit einem GY-BME/P-280 verbunden über SPI verbunden. Im Sketch habe ich nur die PINS geändert und zwar auf: #define BMP_SCK 13 #define BMP_MISO 12 #define BMP_MOSI 11 #define BMP_CS 10 Ich bekomme aber bei der Ausgabe am seriellen Monitor nur "Hyroglyphen" zB 5��,�lh��}��'�O8��m�h,� Mit einem anderen Sketch funktioniert der Sensor einwandfrei. Auch mit einem anderen Nano dasselbe Ergebnis. Hat jemand eine Idee was das Problem sein könnte? Zusatzfrage da ich in C++ nicht so firm bin: Könnte es sein, dass MY_DEBUG oder MY_RADIO_NRF24 das problem verursacht. Was machen diese Definitionen eigentlich? Grüße

Quick Range Check on the WIO-E5-LE. The LE version uses only the low power PA, +14dBm max. Using the default settings except for 915MHz #define MY_SX126x_FREQUENCY (SX126x_915MHZ) #define MY_SX126x_LORA_SF LORA_SF7 #define MY_SX126x_LORA_BW LORA_BW_125 #define MY_SX126x_LORA_CR LORA_CR_4_5 I get about 190 meter range, just walking around the neighborhood, line of site except for some trees and power lines. No tuning on the antenna. Just using a 77.9mm wire. Not as dramatic as some have achieved with LoRa radio's, but plenty good enough for my house and yard : )
