In general, yes, the MySensors framework (library?) should support FOTA a couple different ways (read more at link). Were you aware of this, or is there some problem with your particular hardware?
@NielBierman said in FOTA possibilities for remote sensor network:
Raspberry pi
I don't know yet whether you even need to change your gateway from microcontroller (uC) to Single Board Computer (SBC) or not. However if you do (or are looking for a controller, or whatever), by all means, please do yourself (and all of us) a favor and do a little more research as there are lots of better options out there for SBC nowadays, than RPi!
For me, uC have been fine for gateway although I do use some SBC for controllers, MQTT broker, and various other GNU/Linux based servers/services and they are wonderful for that. But perhaps your needs are different from mine.

The node is a very simple one. So I never considered boot loaders, as the node would not need changing sketches during it's lifetime. I have boot loading functionality on my other designs, this one is a minimal board. Any extra chip would beat the purpose of the word "minimal".
It's a dumb node for a reason
Just to let you know that I solved the issue.
I found a library where you can control the speed and make sure it get to it's position.
You can find it here: https://github.com/netlabtoolkit/VarSpeedServo
I incorporated it in the Mysensor sketch and it works eventhoug it looks like it only goes like 90 degrees but it's enough for me :
#include <MySensor.h>
#include <SPI.h>
#include <VarSpeedServo.h>
// #include <Servo.h>
#define SERVO_DIGITAL_OUT_PIN 3
#define SERVO_MIN 0 // Fine tune your servos min. 0-180
#define SERVO_MAX 180 // Fine tune your servos max. 0-180
#define DETACH_DELAY 900 // Tune this to let your movement finish before detaching the servo
#define CHILD_ID 10 // Id of the sensor child
MySensor gw;
MyMessage msg(CHILD_ID, V_DIMMER);
VarSpeedServo myservo; // create servo object to control a servo
// a maximum of eight servo objects can be created
// Servo myservo; // create servo object to control a servo
// a maximum of eight servo objects can be created Sensor gw(9,10);
unsigned long timeOfLastChange = 0;
bool attachedServo = false;
void setup()
{
// Attach method for incoming messages
gw.begin(incomingMessage);
// Send the sketch version information to the gateway and Controller
gw.sendSketchInfo("Servo", "1.0");
// Register all sensors to gw (they will be created as child devices)
gw.present(CHILD_ID, S_COVER);
// Request last servo state at startup
gw.request(CHILD_ID, V_DIMMER);
}
void loop()
{
gw.process();
if (attachedServo && millis() - timeOfLastChange > DETACH_DELAY) {
myservo.detach();
attachedServo = false;
}
}
void incomingMessage(const MyMessage &message) {
myservo.attach(SERVO_DIGITAL_OUT_PIN);
attachedServo = true;
if (message.type==V_DIMMER) { // This could be M_ACK_VARIABLE or M_SET_VARIABLE
int val = message.getInt();
myservo.write(SERVO_MAX + (SERVO_MIN-SERVO_MAX)/100 * val,255,true); // sets the servo position 0-180
// Write some debug info
Serial.print("Servo changed. new state: ");
Serial.println(val);
} else if (message.type==V_UP) {
Serial.println("Servo UP command");
myservo.write(SERVO_MIN,255,true);
gw.send(msg.set(100));
} else if (message.type==V_DOWN) {
Serial.println("Servo DOWN command");
myservo.write(SERVO_MAX,255,true);
gw.send(msg.set(0));
} else if (message.type==V_STOP) {
Serial.println("Servo STOP command");
myservo.detach();
attachedServo = false;
}
timeOfLastChange = millis();
}
i use the simplest boxes that you find,that suface mount with 4 screws and ruber on door.
But be carefull with wall mount screws. if you drill the back of the box ,water come in beind this box. so this ones,the scrfew holes are outside the encosure an box is sealed...
another tip is drill on bottom for pass cables but put some neutral silicone. hot glue let water come in with time because expansion coeficient is diferent that the plastic box and open gaps
