Nuaire Drimaster PIV feature enhancement wishlist

[jrb80]

The Nuaire Drimaster PIV is supported by ramses_cc but provides limited functionality and in my setup, the sensor entities don't provide any data/change values. That said, Faking the wireless remote works brilliantly. The following commands are supported through faking;

Nuaire 4-way switch:

• Fan normal
• Fan boost (purge)
• Heater auto
• Heater off

I am suggesting some feature enhancement ideas for consideration, not all may be technically possible due to Nuaire's implementation. Unfortunately I am unable to help with coding but could help with the packet data collection and software testing!

Sensors:

• Fan mode (Fan normal, Fan boost (purge), Heater auto, Heater off)
• Fan speed status - speed 0 (low) through to 6 (high)
• Heater status (on/off)
• Filter status (clean/dirty)
• Runtime hours

Commands:

• Filter change reset
• Fan speed change (0 through to 6)
• Standby mode (speed 0 turns fan "off")

The Nuaire Remote Monitoring Device confirms that runtime hours and filter status is reported by the Drimaster.

AFAIK (knew) - the Nuaire PIV should expose some sensors in HA via ramses_cc - I will look at this (after I have finished refactoring evohome.

I had a Drimaster Eco Heat HC, but it is crrently sitting in a box, due to last year's attic conversion.

In any case, I would love to see a packet log of the remote device interrogating the PIV - that information could expose new insights.

It appears the 31D9 & 31DA packets do not contain this data (they could - there's space allocated in the payload, but these values never change).

Looks like we'll have to see what packets the DRI-ECO-RM send to the PIV!

That's consistent with my experience, shame. It seems like only a partial (poor) protocol implementation by Nuaire.
