Esmart3 doesn't show sensors

[btmerz]

Hello, I tried to implement my Esmart3 in Esphome an dtried to use your code. I was succsessfully compiling and uploading the yaml file. Unfortunately I don't get any sensos shown.

Here is my code:

Perhaps you can help me out here...

[randybb]

Looks ok to me as you have only id: under your sensors, which means you don't want to expose them to HA. Otherwise you would use name:.

[ssieb]

As with any esphome sensor, you have to give it a name: or it's internal only.

[btmerz]

Thanks for your help. Now I can see the sensors Perhaps it would be helpful, if you include that in the readme file, as I copied the code from there...

Unfortunately I don't get any sensor-values. Maybe my RS485 module is faulty. I will check later... Thanks again.

[ssieb]

That's standard esphome config behaviour. However, in newer examples I have been putting names instead of ids, so I might update that at some time.

[btmerz]

Hello Samuel, I now have ordered a new uart - RS485 module and the ESPhome firmware running. Unfortunately I don't receive any sensor data from the Esmart. The RX / TX LEDs doesn't flash also. Pin 1 is on A and Pin 2 is on B. Do you have any advice?

[ssieb]

Come find me on the esphome discord server. It will be easier to help there.
