Sensor isn't sending data

FAQ
1

Hello,

I’ve tried to reinstall my sensor (after quite some time). I can see it is connected to my wifi but I see no data on grafana website (PM sensors - Dashboards - Grafana). What could I’ve done wrong ?

Thanks for your help.

The sensor seems to be not connected to the internet.

Can you check the DHCP client list on your router ?

Thanks for your reply. I’m not good in IT: not sure what you mean by DHCP client list. What I can see on my router is the PM sensor and its IP (Adresse IPv4: 192.168.178.154). But you are right: it doesn’t connect for long. It gets disconnected shortly after I can see it on my router client list :frowning: Anything I can do ?

I had 2 sensors failing with strange behaving.

The solution was

  • Make a backup.(settings)
  • Erase sensor (best is write a 4 Mb file to the sensor)
  • Re flash sensor

4 Mb file and FlashESP8266

Please change the usb charger for o better one. At least 2A.
