@workshopninja Yes, this is basically what I did with an Arduino MKR1000 WIFI some years ago. There are some #defines for the EEPROM in the code. But for me it worked out of the box with a 24LC32P.
See also in the MyS lib code:
But in the end I switched to the ESP8266 because it also has WiFi and is much cheaper. The support for external libraries is also much better than with the SAMD.
@Jodaille The buckets are nice for measuring the amount of rain that has fallen over a period. But with light rains changes are the bucket won't tip. The normal rain sensors are useful for closing sun screens when it rains. Because they will always give a signal when it rains. Regarding the amount of rain that is falling.
For the weather sensors I use an Alecto one. I can connect it Domoticz using an RFXtrx433E transceiver. But it's still on my bucket list to replace all of those with a mysensor version. For the wind direction and speed I'll be using a AMS AS5600 since they are very precise and don't need interrupts. So I can use one arduino for the complete weather station.
But currently a real rain sensor is higher on my todo list, as we will get a new motorized sunscreen xd
I can confirm the solution posted by FarmerEd works for me. I was able to transmit from a Lora32u4 ii (node) to a TTGO Lora32 gateway.
As pointed in his post, the right line was:
#define MY_RFM95_IRQ_NUM digitalPinToInterrupt(7)
instead of #define MY_RFM95_IRQ_NUM MY_RFM95_IRQ_PIN
or #define MY_RFM95_IRQ_NUM 7
Thanks very much again for taking the time to post the solution.
