@electrik said in Wake-up by interrupt doesn't work:
If the delay is not of importance to you, you can also have the sensor request its state from the controller each time it wakes up. No special modifications are needed than.
It's true. But the controller must switch its relay state without having ack received from the node. That's not what MySensors plugin for Vera does. But you gave me an idea to implement an additional relay buildin into the gateway which will work as a proxy for my real actuator. Thank you!
@Redguy Did you succeed talking modbus and sending to mysensors network ? I have a small mysensors over rs485 network and would like to add this device : https://fr.aliexpress.com/item/4000478781091.html?spm=a2g0o.cart.0.0.1d513c00qfPO3K&mp=1 it would be convinient to use the same cables, ideally the gateway could make the translation directly.
@projectMarvin here's the next gen project that is actually a HW sensorTag but also mainly an nRF52840 firmware compatible with openthread and my previous gen simple mesh framework. The openthread is quite simple as you no longer have to worry about app layer when using directly json from the uC

Hello friend,
any progress on this ? I plan to buy a power meter and it would be awesome to read it over my existing rs485 mysensors network ?
can mySensors and modBus protocol coexist on the same physical line ?
I did more investigation played around with sleep outside of mysensors and found a bit of code in a proximity sensor example:
// Reset flag and clear APDS-9960 interrupt (IMPORTANT!)
isr_flag = 0;
if ( !apds.clearProximityInt() ) {
Serial.println("Error clearing interrupt");
}
I then needed to play around with delays to allow the sensor to catchup..
void loop() {
delay(1000);
Recoding back to MySensors
if ( !apds.clearProximityInt() ) {
Serial.println("Error clearing interrupt");
}
wakeupReason = sleep(digitalPinToInterrupt(INT_PIN), FALLING, sleepTime);
setting up the interrupt pin with a pullup forced the FALLING when pin dragged down by the sensor.
void setup() {
pinMode(INT_PIN, INPUT_PULLUP);
All this is on caveat it makes it through some more testing.
I have built 2 nodes with E01-ML01S (the cheapest module) and I have pretty good experience with them so far.
I didn't have to use any capacitors to improve range, they are directly connected to some medium-quality Arduino Nano GND/3.3V.
One of them is a lighting controller node, ~3 meters from the PA/LNA gateway (+ a 30cm wall) on the same level as the gateway.
The other one is a repeter node and is ~10 meters from the gateway (+ a 20cm wall, same level as the gateway). In this case, radio orientation was important to get a good signal.
One of the test modules could communicate with the gateway through 2 walls and a the ceiling (steel-bar reinforced).
All-in-all, I am satisfied with the signal stability of these modules.
It is a bit finicky to solder the wires to the module because the pads are very small.
I always put some solder on the pads first and reheat when I attach the wires.
