hey, I build my own plant watering system with an attiny85.
The problem: the code works perfectly on an arduino uno but not on the attiny85.
It don't turn on the pumps, maybe because it can't read the values well...
Attiny85 code:
// +-\/-+
// Ain0 (D 5) PB5 1| |8 Vcc
// Ain3 (D 3) PB3 2| |7 PB2 (D 2) Ain1
// Ain2 (D 4) PB4 3| |6 PB1 (D 1) pwm1
// GND 4| |5 PB0 (D 0) pwm0
// +----+
#include <avr/sleep.h> // Sleep Modes
#include <avr/power.h> // Power management
#include <avr/wdt.h> // Watchdog timer
#define SENSOR1 3 //Attiny2
#define SENSOR2 2 //Attiny3 = P2
#define PUMP1 0 //Attiny5
#define PUMP2 1 //Attiny6
#define RELAY 2 //Attiny 7
int SensorValue1; //Read Value
int SensorValue2; //
int ValueP1; //Value percent
int ValueP2; //
ISR (PCINT0_vect)
{
// do something interesting here
} // end of PCINT0_vect
// watchdog interrupt
ISR (WDT_vect)
{
wdt_disable(); // disable watchdog
} // end of WDT_vect
void resetWatchdog ()
{
// clear various "reset" flags
MCUSR = 0;
// allow changes, disable reset, clear existing interrupt
WDTCR = bit (WDCE) | bit (WDE) | bit (WDIF);
// set interrupt mode and an interval (WDE must be changed from 1 to 0 here)
WDTCR = bit (WDIE) | bit (WDP3) | bit (WDP0); // set WDIE, and 8 seconds delay
// pat the dog
wdt_reset();
} // end of resetWatchdog
void setup()
{
resetWatchdog (); // do this first in case WDT fires

{

}
}

SensorValue2 = analogRead(SENSOR2);
ValueP1 = map(SensorValue1, 0, 400, 100, 0); //map to percent // 0 to 400 because this is the range for the perfect soil moist

The sleepmode is from here(but I don't think this is the problem):http://gammon.com.au/forum/?id=11497&reply=6#reply6
I'm using this type of sensor:https://www.amazon.com/Kuman-Moisture-Compatible-Raspberry-Automatic/dp/B071F4RDHY/ref=sr_1_4?ie=UTF8&qid=1544797339&sr=8-4&keywords=soil+moisture+sensor
I attached my cuircitdiagramm(LED should be pumps)
please help me and excuse my bad english, I'm from germany
