The sensors come with the default calibration so this method is only needed if you want to make your own adjustments. + +  + +1. Take your PLT-1 out of the soil and clean off the probe. It is important to get the dirt off to have the best calibration. +2. Make sure the PLT-1 probe is sitting in the air or on a dry non conductive surface and plugged in. +3. Visit the device's entity drill down page in Home Assistant and scroll down to the diagnostics section. Enable the entity "Soil ADC" +4. Give the sensor a minute for this new entity to populate +5. Once the value is populated take the value and put it into the "Dry Voltage" entity +6. Now place the prob portion of the PLT-1 into a cup of water. Be careful to not dunk the entire sensor, only the exposed PCB below "Apollo" and the horizontal line can be exposed to water +7. Grab the "Soil ADC" value now and put the value into the "100% Water Voltage" entity +8.
