When you run the wr_rrd_update.py, it should store the data in sensors.rrd and weather.rrd file in /usr/share/weatherradio.
wr_rrd_lastupdate.py creates a JSON document in /usr/share/weatherradio/data
The RTsensors_lastupdate should look like that:
{
"BME280_Hum":null,
"BME280_Pres":null,
"BME280_Temp":null,
"DHT_Hum":29.70000076,
"DHT_Temp":24.10000038,
"MLX90614_Tamb":23.90999794,
"MLX90614_Tobj":24.42998695,
"TSL2591_Lux":19.059606549999998,
"timestamp":1650283441000

Ok that looks good.
Do you perhaps not have write permissions in the folder?
Can you run it with sudo?

I think i had the same issue.
I had to modify the paths in wr_config.py
It was:
def __init__(self):
# setup configuration
self.config = ConfigParser(interpolation=None)
self.config.optionxform = str
# default values
self.config.add_section('WeatherRadio')
# web server configuration
self.config.set('WeatherRadio', 'INDISERVER', '0.0.0.0')
self.config.set('WeatherRadio', 'INDIPORT', '8624')
# RRD storage holding time series data
self.config.set('WeatherRadio', 'RRDFILE',
'/usr/local/share/weatherradio/weather.rrd')
# RRD storage holding time series for raw sensor data
self.config.set('WeatherRadio', 'RRDSENSORSFILE',
'/usr/local/share/weatherradio/sensors.rrd')
# path to the JSON files holding the data
self.config.set('WeatherRadio', 'DATAPATH',
'/usr/local/share/weatherradio/html/data')
# path to the directory holding web cam images and videos
self.config.set('WeatherRadio', 'MEDIADIR',
'/usr/local/share/weatherradio/html/media')Edit do:
def __init__(self):
# setup configuration
self.config = ConfigParser(interpolation=None)
self.config.optionxform = str
# default values
self.config.add_section('WeatherRadio')
# web server configuration
self.config.set('WeatherRadio', 'INDISERVER', 'localhost')
self.config.set('WeatherRadio', 'INDIPORT', '7624')
# RRD storage holding time series data
self.config.set('WeatherRadio', 'RRDFILE',
'/usr/share/weatherradio/weather.rrd')
# RRD storage holding time series for raw sensor data
self.config.set('WeatherRadio', 'RRDSENSORSFILE',
'/usr/share/weatherradio/sensors.rrd')
# path to the JSON files holding the data
self.config.set('WeatherRadio', 'DATAPATH',
'/usr/share/weatherradio/html/data')
# path to the directory holding web cam images and videos
self.config.set('WeatherRadio', 'MEDIADIR',
'/usr/share/weatherradio/html/media')Read More...
It looks like there is a letter "t" in "target" missing.
Failed to enable unit: "multi-user.targe" is not a valid unit name.
It should be: "multi-user.target"

I switched from a Raspi 4 to a RockPi 4B with 128 GB eMMC. Same form factor but much faster. Since then i haven't had a single chrash and i'm very happy with it.
