I'm wondering if anyone can help.
I have used this with an ESP8266 board in an outside hedgehog box. It weighs the hogs as they are feeding. Everything works, however the zero reading drifts massively being outside. I have tried a previous auto tare which keeps the reading at 0g throughout the day, but the weight is quite a distance out once the temperatures drop on the night.
Can anyone include some code so that I can use a spare GPIO pin on the board so as the hog enters the box, the scales zero themselves before it reaches the main compartment ?
Current code is:
globals:
- id: constant_weight
type: float
`captive_portal:
sensor:
-
platform: hx711
id: weight
name: "HX711 Value2"
dout_pin: GPIO14
clk_pin: GPIO12
gain: 128
update_interval: 5s
unit_of_measurement: g
filters:
calibrate_linear:
- 68604 -> 0
- 626959 -> 2030
on_value:
- if:
condition:
- lambda: |-
static float last = 0.0;
float diff = x - last;
last = x;
return x < 50.0 && diff < 1.0 && diff > - 1.0;
then:
- lambda: 'id(constant_weight) = x;' -
platform: template
name: Hog Weight2
icon: mdi:scalee
unit_of_measurement: g
accuracy_decimals: 0
lambda: 'return id(weight).state;'
filters:
- lambda: 'return x - id(constant_weight);'
- lambda: 'return x >= 10.0 ? x : 0;'
- delta: 0.5`
