uHoo Indoor Air Quality monitor

frankvandenhurkfrankvandenhurk Member

I just received my uHoo Indoor Air Quality monitor (https://uhooair.com/). Is it possible to integrate this with Athom Homey? I would like to take action when there is a problem with the air quality (e.g. activate some extra ventilation).

Did some digging:

Nmap scan report for 192.168.160.54
Host is up (0.20s latency).
Not shown: 909 closed ports, 90 filtered ports
PORT   STATE SERVICE
80/tcp open  http
MAC Address: F0:C7:7F:XX:XX:XX (Unknown)
Nmap done: 1 IP address (1 host up) scanned in 1591.01 seconds

On port 80, there is only a mysimplelink interface, and it looks like it is only available at boottime. Works with its own app on your smartphone, can't find anything about an API.

Any idea's if there are posibilities to integrate?

    Sniff the network-traffic and see if there's detectable data-traffic?

    Took some time to change my network layout, but now I have a device that can to tcpdump in the path of the traffic. First output:

    I'll try to get full packet captures, to see if there is readable data in it.

    Unfortunately, I am afraid that won't help. A 256 bytes payload othat doesn't make sense..... :(

    I can you send the content of the payload if you want to analyse, but I wont't be posting it on a public forum because I don't know what the content means.

    Hey guys,

    Thought you may find this useful. It is really a exhaustive list of things you can do to improve the quality of air in your home, and you just may find some useful information on it.

    Improve home air quality

    In using the xiaomi pm2.5 (around 50 € in China). And it works good with the athom xiaomi app:
    https://apps.athom.com/app/com.xiaomi-miio

    First setup is a bit of a hassle, since it only works if you set your xiaomi account to Chinese. (And im sure they keep track of my homes airquality from china?)
