[TS0601 (TOQCB2-80-2P) / _TZE284_mrffaamu] Exposures

What happened?

I have a TS0601 - TOQCB2-80-1P and the power, voltage and current always read N/A while the Power A, Voltage A and Current A read OK. Temperature and Energy are OK as well. This becomes a problem because when interfaced to Homey only the common power, voltage and current are displayed which always show "Last value unknown".

What did you expect to happen?

I would expect that all exposures are sent to Homey rather than the common power, voltage and current which appear to do nothing.

How to reproduce it (minimal and precise)

Start at the TOQCB2-80-2P device definition and inspect how the common power, voltage, and current exposures relate to the working A variants. Reproduce with the reported device data if available; done means the Homey-facing exposures provide the device's available readings. No debug log or database entry is provided, so the exact code path still needs locating.
