NRF24 Weather Station Issues



  • I started with MySensors several years ago and then had to put it down because of life. I finally picked it back up in the last year. I have everything up and running using ESP8266 gateway and a Home Assistant controller (RPi 4). I have several sensors up and running, half sensebender micro and half arduino nanos with AHT20's on them. I have tried to build a rain gauge, light sensor, temp/hum sensor by modifying the rain gauge code on the build section to accommodate the AHT20. For the life of me, I can't get this thing to be recognized by the controller. It will assign an ID and then goes into this FPAR loop. The gateway is seeing the various requests, but it will not pair. I've tried several known working radios, I have tried PA LNA radios with kapton tape/foil/kapton tape and a ground wire drain on the foil. I've tried various combos of capacitors. I currently have a 10 uf electrolytic & a 2.5 nf ceramic capacitor on a PA LNA that I can get to work fine on another arduino, but not this one. I have basically built the circuit shown on the rain gauge build page on a electrocookie board, including the debouncing on the hall sensor for the rain bucket tip sensor. Any ideas? I'm at a loss.

    Here's my modified rain gauge code:

    /*
     Arduino Tipping Bucket Rain Gauge
    
     October 6, 2017
    
     Version 2.1
    
     Arduino Tipping Bucket Rain Gauge
    
     Utilizing a tipping bucket sensor, your Vera home automation controller and the MySensors.org
     gateway you can measure and sense local rain.  This sketch will create two devices on your
     Vera controller.  One will display your total precipitation for the last 5 days.  The other, 
     a sensor that changes state if there is recent rain (up to last 120 hours)  above a threshold.  
     Both these settings are user definable.
    
     There is a build overview video here: https://youtu.be/1eMfKQaLROo
    
     This sketch features the following:
    
     * Allows you to set the rain threshold in mm
     * Allows you to determine the tripped indicator window up to 120 hours.
     * Displays the last 5 days of rain in Variable1 through Variable5
       of the Rain Sensor device
     * Configuration changes to Sensor device updated every hour
     * Should run on any Arduino
     * Will retain Tripped/Not Tripped status and data in a power interruption, saving small amount
       of data to EEPROM (Circular Buffer to maximize life of EEPROM)
     * LED status indicator
     * Optional Temp/Humidity (DHT-22 or DHT-11) and Light LUX (BH1750) sensors. To use, uncomment
       #define AHT_ON  and/or #define LUX_ON
     * Optionally send total accumulation of each day's rainfall or send only individual days rainfall totals.
       Uncomment #define USE_DAILY to display individual daily rainfall.  If it is commented out it will display
       a cumulative total rainfall (day4 = day1+day2+day3+day4 etc)
