Sleep: 7160 sec @ 1mA = 1.99 mAh
Total: 7.49 mAh per cycle

WiFi Upload: 5-15 seconds @ 80-150mA
Power Down: 5 seconds
Sleep: ~7100 seconds @ 1mA
Estimated Active: 25-55 seconds @ 80-150mA = ~3-8 mAh

Estimated Total: ~5-10 mAh per cycle
Battery Life: Likely 2-4 months (depends on WiFi distance)
Power Considerations:
- WiFi is more power-hungry than GSM during active time
- WiFi is faster (shorter active window = better battery)
- Assumes good WiFi signal (~1 meter away)
- Poor WiFi signal could significantly increase power usage
- ESP-01 well-documented with many Arduino examples
- WiFi communication well-established
- SHTC3 sensor readily available with libraries
- HX711 unchanged (no issues)
- No fundamental technical barriers
- All components readily available (AliExpress, eBay, etc.)

- No specialized or rare components needed
- 50-80% lower hardware cost than GSM
- No monthly SIM plan costs
- Total 2-year savings: €150-500+
- WiFi power consumption higher during active time
- Battery life may be 2-4 months (vs 3 months with GSM)
- Acceptable trade-off for cost savings
- Power budget needs careful testing
- Must completely rewrite communication layer
- Different protocol (HTTP vs AT commands)
- New sensor library (SHTC3 vs DHT22)
- WiFi connection management needed
- Estimated rewrite: 3-5 hours

- Bidirectional shifter (TXB0104) recommended
- Don't skip this - ESP-01 damaged otherwise!
Problem: Arduino pins D10-D11 might be used elsewhere Impact: I2C communication fails Mitigation:
- Use dedicated I2C pins (D10-D11 or SDA/SCL)
- Or use A4/A5 (standard I2C pins)
