Hi all,
I need to re-flash my sensor, is unable to connect to wi-fi (wi-fi 5) and harvesting on FAQ the only solution possible is to re-flash the sensor.
My sensor has worked for (at least) one year since 7/1/24 00:30 after this moment the sensor is became offline.
Now I can connect to it when is in router mode but is unable to re join my wi-fi network.
Is possible to flash using web connection? (the sensor is on my roof!)
Thank you.

I would be surprised if the software is causing this kind of issue. To which faq are you referring?
Regarding your question, likely you need a physical connection to flash the node-mcu again.
Hi @v6tunnler
thank you for your answer.
I’m also surprised about this problem.
The sensor has worked for a lot of time, but suddenly has stopped working. I’ve cut off the power and the sensor has re started in access point mode.
After it I had tried, finding in the list my SSID, to insert the wi-fi password. This was unsuccessfully, I’ve made a lot of try.
Searching for “wi-fi problem” or “unable to connect” I’ve found only that the way to solve was to flash again the firmware.
Let me know if you have any idea before that I need to go on my roof!
Best regards.

If possible, try to get the router and the sensor in a closer range.
Hi,
It would be important to read the USB log to know exactly what happens.
Like @air-ais says I think it has to do with the range of the router.
Thank you,
BTW the sensor has worked for more than one year.
Has suddenly stopped working, now is online without any explication.
Boh!

I am a bit curious now, do you have a photo? 
Thanks^^, Well done 
No problem. The same thing is happening to me from time to time.
I get the following stats from that sensor:
| WiFi | signal strength | -80 dBm |
|---|---|---|
| WiFi | signal quality | 40 % |
As you can see it’s a bit weak, but it’s not very convenient to rearrange things, and it’s not something that happens regularly.
Hi @air-ais I know that sometimes the sensor appear offline, btw is the first time that the sensor is offline for more days!
Thank you for your help!
Leo
You are welcome! Good to know it’s working alright again.
40 % is still quite OK.
