Ac unit sometimes not responding to status request

[MotiGross]

Hi,
So, as mentioned here already, I used this great GitHub with it's info to build from scratch my PLC code,
my code does :
--> connecting to WIFI
--> get's the unique key
--> send operation commands,
--> ask for current status
and I'm polling status from the AC units every ~5 sec, i have in my home 4 AC units.

I've seen that sometimes, at the moment not sure exactly why , the AC unit not respond to status request, but it does do any command I'll ask ,so it's not general communication problem.

My units are having version V1.1.13, they are 5 years old. and I'm wonder if it worth trying upgrade their FW.

Any one has any experience with such behavior?

cheers!

during the time i'm using my code, i seen many times that i'm asking for "status" and the device not reply with answer. using the app "smart" i upgrade all my 4 devices from v2.2 to v2.5 ,i hope that will fix the "no response" I'm seeing.
FYI , i'm asking for status once every 5 sec. how often you're asking for status?

In GreeBlynkBridge I've set the polling interval to 10s, but I'm not aware of any limitation regarding the frequency of status requests. It should work. It's possible that there is a bug in the firmware or the WiFi network loses packets coming from the AC. You should check the WiFi signal strength in the router/AP. Since it's UDP, the unit doesn't re-send the packets when they are lost.
