OTWG + NodeMCU problem

Post by simonh29 »

I have a problem with OTGH (nodo-shop) + NodeMCU. When connected it seems to be resetting or dropping out?

On the hardware the green light is flashing... then every few seconds all 4 lights flash and the NodeMCU blue light flashes too. Is this normal?

I tried the OTmonitor but that seems to stop receiving data after a short while.

Looking on Domoticz I have the following logs:

Code: Select all

Re: OTWG + NodeMCU problem

I've tested the NodeMCU unplugged from the OTGW and powered by a micro USB. The NodeMCU is connected to the WiFi and stable. The status page updates with the uptime.

I also tested the OTGW without the NodeMCU and the green light only flashes away as signals are been received. Obviously, I can't see what's going on without the NodeMCU.

I then reconnected the NodeMCU and every few seconds you get a blink of all lights on the OTGW and the blue light on the NodeMCU.

I'm presuming this a problem and the gateway is resetting or something similar ?

It is from nodo-shop and I got them to solder it for me hoping to save some valuable time.

Nodo-shop got in touch and it looks like I missed the following on the setup of the NodeMCU: WD I2C: 38
