Hey there @dgomes, mind taking a look at this feedback as it has been labeled with an integration (integration) you are listed as a code owner for? Thanks!

The integration sensor is a math calculator... if you have a negative value 100% of the times it's the source sensor that turned negative

[d3zit]

Would it be possible to add an availability template to the integration one? in order to prevent it from working if the source sensor is negative?

[dgomes]

The integration inherits it's availability from the source sensor
