Validating lambda behaviour before it's uploaded into the device

[agf102]

Describe the problem you have/What new integration you would like

Every time I need to update some lambda on an esphome device I have to upload into a device to see if will compile and see if I’ve written it correctly.

Is it possible to create an equivalent of the template section in HA developer tools so I can test my esphome templates without deploying first.

Even better if there’s a way of easily exporting sensors on esphome into the developer tool so I can test with real device sourced data

Please describe your use case for this integration and alternatives you've tried:

If you go Install->Manual Download it will build without trying to load. Might not be too hard to add a compile option might be accepted.
