Hi All,
I’ve been running HA for many years and have recently come across an issue with MQTT/sensor updates.
I have a number of home brew sensors that send temp/humidity every minute, which all works as intended,or so I thought!
The issue is, that I am trying to create an automation to control a dehumidifier via a bathroom sensor and a trend sensor.
I can see from the logs that the sensors are updating every minute as expected…
2020-02-11 11:55:47 DEBUG (MainThread) [homeassistant.components.mqtt] Received message on Climate/Bathroom/sensor1: b'{"temperature":"18.60","humidity":"46","battery":"90"}\r'

However, if there is no change in temp, or humidity, the sensor is not updated.
This has not been an issue before, but when using the binary sensor (Trend) the gradient either doesn’t exist, or is erroneous.
I can understand if duplicate MQTT values are not stored to save storage space, but is this intended behaviour, or am I missing something in the config?
Thanks in advance,
Mark
