Posible NTP problems with internet restricted Wemos ESP8266
pvossel opened this issue · comments
In my network I have alot of ESP8266 and ESP32 devices (Tasmota, WLED, Zehnder, etc).
I want to restrict internet access for these devices.
Only downside is, if they try and communicate with an external NTP server but cant reach it they become "unavailable" for a vew seconds. Something is happing to the WIFI. Not sure if its a reboot of the ESP8266 or reconnect with WIFI.
I can mitigate this with most of my ESP8266 devices by using a local NTP server.
Now I am also experiancing alot of "unavailable" Milight lights in Home Assistant.
My assumption is that this is the same problem.
Im running Milight Hub on a Wemos D1 mini (1.10.8 d1_mini).
Posible solution, configurable ntp server?

I've updated to the latest firmware 1.11.1 (d1_mini).
Same issue here.
Serial connection not showing any usefull logging for troubleshooting.
Hey guys, sorry for the late reply here.
I don't use NTP in this project. It's possible something else is using it behind the scenes, but I kind of doubt it.
I changed the default WiFi mode from N to G in 1.11 -- I suspect this might be the cause. Can you try swapping wifi mode to N?
It was already on N.
Changed it to G. Problem solved!
