    Hello.

    I’m trying to integrate my A3 (HW105, radiation sensor but no ozone sensor) to my local Home-Assistant (again).

    However, when I ask the A3 for the data in JSON format, there’s not radiation value:

    {"data":{"id":"820000E8","type":"8","detector":"SI29BG","cpm":4,"voltage":381,"temperature":19.34,"humidity":57.64,"pressure":94008,"voc":929109,"co2":416,"noise":39.25,"ch2o":0.00,"pm25":5,"uptime": 1839423}}

    How do I get the radiation value?

    I have a different result (with a “rad” variable) when using the embedded website.

    I tried just now: 

    uRADMonitor 820000E8
type:8 hw:105 sw:135 SI29BG RAD:9CPM
VOL:380V 20%
T:18.73C
P:93920Pa
H:59.94RH
VOC:556745
N:33.53dB
CH2O:0.00ppm
PM2.5:6ug/m^3
CO2:451ppm
UP:1891393s WDT:12s/400s

    vs

    {"data":{ "id":"820000E8","type":"8","detector":"SI29BG","cpm":9,"voltage":380,"temperature":18.74,"humidity":60.36,"pressure":93925,"voc":696381,"co2":444,"noise":33.53,"ch2o":0.00,"pm25":5,"uptime": 1891483}}

    So I think I got it.
    The “radiation” value is “cpm” in JSON.

    hi! Would you share your recent HA script? Would you do a short article on it? Here are a few others: https://www.uradmonitor.com/blog/?s=home%20assistant
