Not discovered?

[Ramdough]

Ok, so I am a bit of a newby….but please help.

I have copied your code directly but updated the MAC address, IP number, and unique ID (so it stood out more). My code compiles and writes to the arduino successfully.

I can see my arduino and pig it on the network.

Under MQTT on HA, I am able to publish to myself using the manual publish and listen feature. I have listen set to #, so I am listening to all traffic. So mosquito appears to be working. Discovery is on.

For some reason, I do not get a new sensor created using this code.

What should I try next?

[Ramdough]

Any thoughts anyone?

Got any code to share?

Got any code to share?

I used this exact binary-sensor example code but changed the MAC address, the unique ID, and the broker IP address.

I am using an arduino mega and plan to modify this code to read all dio pins.

Same on esp32 binary sensor is not discovered but is published on MQTT... (checking with MQTT explorer)

Hi @Ramdough, which version of Home Assistant do you use?

[romoloman]

With version 2.1.0 everything is fine on HA 2024.5.4, but still persist the issue of multiple devices of the same type in the network, so I had to use the develop branch that implements enableExtendedUniqueIds() using the mac address of the esp 32 as device id.

Hi @Ramdough, which version of Home Assistant do you use?

I have auto updates so I am always on the latest version.
