5 years ago Hello, the python interface always loads all data of a device, because FHEM offers no other possibility. The data is then filtered by python-fhem. Therefore, from a performance perspective, it is better to filter the readings yourself if you need several readings from one device, like this:
data = fh.get_device_reading("myWeather", ["fc1_day_of_week", "fc1_code"], value_only=True)
temp_1_code = data["temp_1_code"]
temp_1_wday = data["temp_1_wday"]Your problem is, that the json data coming from FHEM are not well-formed and can not be parsed by python. I assume that this error is in jsonlist2 of FHEM or in telnet transmission. Did you test if the error also occurs with http?
Maybe this could be catched by requesting the data again when a decode error occours @domschl ? Maybe with a parameter that sets how often?
To catch this problem for the moment you could also do something like this:
# Try 5 times to get correct data
for x in range(5):
data = fh.get_device_reading("myWeather", ["fc1_day_of_week", "fc1_code"], value_only=True)
if data:
break

Hi, If use f.ex. temp_1_wday = fh.get_device_reading("myWeather", "fc1_day_of_week") temp_1_wday = temp_1_wday['day_of_week'] temp_1_wday = temp_1_wday['Value']
or temp_1_code = fh.get_device_reading("myWeather", "fc1_code") temp_1_code = temp_1_code['fc1_code'] temp_1_code = temp_1_code['Value']
to get a specific reading. Unfortunately sometimes (not always, and also not everytime the same device) i get all readings. Not sure if it's FHEM related or python-fhem:
or
