Hlep with Rain Sensor calibration?

[deanfourie (Dean)]

Can anyone help me please, i’m trying to calibrate my rain sensor but just seems to always read out.

I came up with a multiplier of 10. But it still seems to be incorrect. On the gauge is written M0.2 so i’m assuming this mean 0.2mm per tip.

I’m not sure how to work out what the multiplier should be.

Thanks

The multiplier is going to be 0.2

Every tip is 0.2mm therefore number_of_tips * 0.2 = total rain.

Here’s’ an example triggered template sensor:

Count history_stats starts at 1, not 0

I assume you are adding up the on and off state flips to get a total and then multiplying that by the tip volume to get the amount of rain? If so here’s an alternative to using history stats: (configuration.yaml) template: - trigger: - id: count platform: state entity_id: binary_sensor.aqara_dw_2_open_closed to: - 'on' - 'off' from: - 'on' - 'off' - id: reset platform: time at: '0:00' sen…

Ah awesome that makes sense. Thank you!

Any idea how I can add a Hourly Rain calculation? I want to measure hourly rain fall?

Thanks Tom!

DIY Zigbee rain gauge

Rain has never been more exiting Last updated: November 2023 Sensor has been running on the same battery since December 2020 Today I want to share with you how I made a wireless battery powered Zigbee rain gauge for $20. It measures the rainfall amount in mm or inches. Furthermore, the battery life is +2 years!

Is there a way to actually test the rain sensor against a known good source? Like a cup…catch rain or something simple like that?

I’m trying to base it off online reports of rain in my area but they seem wrong and they only seem to update every 1 or possibly even more which makes it really hard. It can pour down solid for 1 hour and they will read 0.2 online while my weather station is reading like 6 - 7mm of rainfall.

Thanks
