Wrong behavior of preset

[alexmc1510]

Do you know what could be happening here? As you can see the HVAC is not correctly regulating the temperature according to the preset.

Simple config:

• No features
• Self regulation light
• Auto fan mode Low
• Use internal temp of underlying ON

Basically the system consists on a Haier air conditioning and a son off temp sensor installed in a strategic pleace of the room.

What I am doing wrong? Why the AC is activating far below to the target?

Hello! Can you send your logs?

Your logs are empty....

In order to give you more samples. Same behavior in Living room AC. In this case a Mitsubishi...the other one was a Haier.

Logs export from 18 to 22nd. Where you can see that the regulation is not accurate.

It's the header. The data is after the line '==================='

I see...in that case why? I am executing the service following exactly your instructions...
