S21 does not seem to expose powerful setting (CTXS07LVJU)

[pfak]

Powerful set via remote on CTXS07LVJU:

{"G1":"13NA","G2":"=;\u0000�","G3":"0��\u0000","G4":"05�\u0000","G5":"000�","G8":"0\u0000\u0000\u0000","SH":"502+","SI":"551+","Sa":"022+","SL":"811","Sd":"710","SN":"060+","SX":"081+","SD":"000"}

No powerful:

{"G1":"13NA","G2":"=;\u0000�","G3":"0��\u0000","G4":"05�\u0000","G5":"000�","G8":"0\u0000\u0000\u0000","SH":"591+","SI":"551+","Sa":"022+","SL":"580","Sd":"330","SN":"060+","SX":"062+","SD":"000"}

Thoughts?

SX seems to indicate some kind of status w/ regards to cooling.

[JeanOlivier]

It looks like the temperature target to me. Considering it's reversed like @revk said below.
Powerful setting it to +18.0 for a few minutes sounds reasonable.

[pfak]

[revk]

Remember the S values are read backwards, eg "012+" is +21.0C, if that helps.

Here are results on my CTXS09HVJU unit:

It looks like G3 is '0002' when powerful is active in my case and '0000' otherwise.
It could also be a 20 min timer before it's back to normal, I didn't leave it on long enough to check.

In powerful mode, SX is '081+', which I presume is the 18°C target. But in non-powerful mode it's '022+' whereas I'd expect '021+'.
Sd (compressor?) also changes with the mode but it's unclear to me what it means. SN is weird as well.

I hope that helps!

PS: MQTT is the weirdest way to talk to devices I ever used.

[revk]

D3 would populate info/Den-DaikinAC/tx I expect. The fact it does not give a nak is good. If it works there is no direct reply. But you could set debug and see if the G3 response changes.

A nak means it did not like it. It is basically trial and error at this point.

Do any other values for D3 do anything, like set powerful or any other settings you can work out?

I see what you mean. Not sure where home came from, and I do indeed see boost now (confusingly not Boost which is what I looked for). I see your point. Would normal be better?

[pfak]

Not as far as I can tell, I sent D30001, D30000, D31000, D32000 ..

[revk]

OK it is guesswork, sorry. The D3 was because it lines up with the F3 request and G3 reply. It could be something different, if possible at all. If you find anything that does work, let me know. Sadly there is no public specification for S21 protocol.

[pfak]

I assume you have seen https://drive.google.com/file/d/1LyEWbTcdNucfsnBGTTqissDmnzVDP04R/view?pli=1 ?

[revk]

Not that one specifically - the problem is that it depends on the model as well, as you see. Several people have managed to reverse engineer their model, as I have.

[pfak]

Wonder what the difference is between LVJU and HJVU?

[JeanOlivier]

It's just L -> H. But it's unclear to me as well.

Only thing I can think of is that I'm in a cold part of Canada, so I think my unit is designed to be able to heat the house for a lower outside temp. I think it become inefficient at -20°C, whereas typical heart pumps are inefficient below -10°C. That'd just be useless here.

[pfak]

Weird. I'm in Vancouver and my Heatpump didn't even go into resistive heating mode when we hit -17C in December 2021.

[JeanOlivier]

You may have a similarly cold-targeted unit. Idk what H is for then.

Here, we reach -30 without windchill regularly. I don't use the heat pump under -20, but I have to switch manually. The unit doesn't stop, but the air coming out is not warm.

[JeanOlivier]

According to documentation I found, it's "Major Design Category", but I didn't find a table explaining L vs H.
