I have a bunch of Acurite 609TXCA temperature sensors. They send their temperature over 433MHz and I use rtl_433 to capture that and the data is sent via MQTT to Home Assistant.
Unfortunately they have a pretty high offset and I calibrated and have an offset value calculated for each.
Unfortunately I am not aware of manipulating data in rtl433 directly, or via MQTT.
In Home Assistant, I could create a template sensor for each temperature sensor and add the offset. But this is really cumbersome, especially considering the large amount of these devices I have.
Is there a better/easier way to solve this?
