Re: [weewx-user] Replacement humidity sensor

[tadej.j...@gmail.com]

It works! In the end the solution was so simple. I also changed dewpoint 
from hardware to software calculation and it also works OK. Now I must only 
get one proper sensor instead dht22. 
Thank you all!

 Michael, when trying this I get value N/A for outHumidity so we are 
 getting somewhere, but it is still not replaced with extraHumid1 value. 
 What do you mean with removin it from locals? :)

Re: [weewx-user] Replacement humidity sensor

[tadej.j...@gmail.com]

For testing purpose I used esp32 with dht22 configured as web server. Every 
10 minutes i use cron to wget value from esp32 to a .txt file. Then I use 
weewx user service to read this value into database.

Service:
# -*- coding: utf-8 -*-
import syslog
import weewx
from weewx.wxengine import StdService

class vlagaservice(StdService):
def __init__(self, engine, config_dict):
super(vlagaservice, self).__init__(engine, config_dict)
d = config_dict.get('vlagaservice', {})
self.filename = d.get('filename', '/usb/www/tla/vlaga.txt')
syslog.syslog(syslog.LOG_INFO, "vlaga: using %s" % self.filename)
self.bind(weewx.NEW_ARCHIVE_RECORD, self.read_file)

def read_file(self, event):
try:
with open(self.filename) as f:
value = f.read()
syslog.syslog(syslog.LOG_DEBUG, "vlaga: found value of %s" % 
value)
event.record['extraHumid1'] = float(value)
except Exception, e:
syslog.syslog(syslog.LOG_ERR, "vlaga: cannot read value: %s" % 
e)

Re: [weewx-user] Replacement humidity sensor

Did run run weewxd directly, and check, how the loop packet drop in and

Also: what kind of sensor did you apply to augment your data and how does 
the data go into into you weewx? MQTT?

What I did:
With my ws23xx, I have a outHumidity Sensor that works well below 85%, but

Re: [weewx-user] Replacement humidity sensor

[michael.k...@gmx.at]

As I said: "something like"  "not tested"

Then I'd give 

outHumidity = extraHumid1 if 'extraHumid1' in locals() else None

a try. Still: not tested, an I am just assuming that setting it to None 
when present it will be ignored when accumulating the value over an 
archive_interval. It might be as well necessary to remove it from locals, 
if possible.

Re: [weewx-user] Replacement humidity sensor

When merging sources it is often useful to run WeeWX directly 
, that way you 
can see exactly what is/is not in your loop packets. Frequently it is not 
what you may expect.

With this config you get both, outHumidity and extraHumid1 mixed.

Try, as mentioned above:

outHumidity = extraHumid1 if extraHumid1 is not None else None

 Could you use something like BME280WX from here?

Re: [weewx-user] Replacement humidity sensor

[michael.k...@gmx.at]

With this config you get both, outHumidity and extraHumid1 mixed try:

outHumidity = extraHumid1 if extraHumid1 is not None else None

outHumidity = extraHumid1 

I am getting correct values in extraHumid1 from replacement sensor. I

Not necessary, if the Ecowitt gateway driver can be used it can be run as a

With the ecowitt gateway you need a second weewxd running, as a downside. 
But you can build a whole new station, step by step, around that gateway 
(which is probably way to go, sooner or later).

Do not use a BME280 as an outdoor Sensor, it is not suited for this 
purpose. The operating range is only valid in non-condensing environments. 
In condensing environments, especially below freezing point, these sensors 
are proven unusable. Go for a SHT3x or SHT4x.

Hello i have ws2300 station and my humidity sensor probably died. It

I was thinking of getting external humidity sensor and hook it to 
arduino board and then read humidity values remotely  via crontabs in a 
txt file. Is is somehow possible to "trick" weewx to read this value 
instead of getting it from station because I am using weewx to calculate 
heat index and dew point.

Could you use something like BME280WX from here?
