saving mode (modalità risparmio) stufa unica 10

[merlino1975]

HI. I have another question (by now you must be tired of me).
in the UNICA 10 stove which runs on both pellets and wood the fire powers are respectively
ris (risparmio in Italian)-1-2-3 for wood
and ris (saving)-1-2-3-4-5-6-7 for pellets
I didn't find these values ​​in the states, are they there but I haven't seen them? they are not here? can they be inserted?
ps. In the manual it says (for wood) that the saving (risparmio) mode is a power lower than 1
It is not specified in the pellet operation manual, so I don't know if the same thing applies to both pellets and wood, i.e. that the saving (risparmio) mode consumes less wood and less pellets.
thank you so much

The RIS state will be 0 for the Real Pellet Power and Real Wood Power sensors. (You cannot set the stove to this state yourself with the power controls.)

[merlino1975]

and isn't there a way to simulate this?
this state (savings) is set when the thermostat is off....I imagine that not even the thermostat can be turned off with a command... so you're saying that there isn't even a way to do it? a real disappointment

[merlino1975]

alternative but very imaginative solution would be to disconnect the external thermostat that goes to my thermostat and connect it to an intelligent switch controlled by the home assistant... when I want it closes the contact and triggers the thermostat on or opens the contact and triggers the thermostat off...so with a routine I can take control

Hi, also owner of an unica 10 (and participate to wood mode handling in the integratiln). Even in the wood working mode the stove will go in RIS state when the temperature measured by the navel reach the target temperature. You could not set it manually.

In wood mode, the power mode will mainly act on the fan (and consecutive noise...). It's not clear for me if it also act of on wood combustion (maybe by increasing air in-out to increase or decrease burning).
When switching to RIS mode, it clearly limit air in-out so the wood will burn slowly and you'll save many wood!
Sometime in RIS mide it can detect "out of wood" even if there is many wood, due to fact the remaining combustion is to low and the temp in the fireplace/fume temp is to low as when there is not enough wood...

The integration provides 2 different power entity : one wood power, one for pellet power. At least it should, as i'm not up to date maybe a recent update broke something.

Ciao, anch'io possiedo un'unica 10 (e partecipo alla gestione della modalità legna nell'integraln). Anche nella modalità di lavoro legna la stufa andrà in stato RIS quando la temperatura misurata dall'ombelico raggiunge la temperatura target. Non è possibile impostarla manualmente.

-----iit would have to be, or absolutely find a way to do it, or request it because it is not possible not to be able to do it at wil

In modalità legna, la modalità potenza agirà principalmente sulla ventola (e sul rumore conseguente...). Non mi è chiaro se agisca anche sulla combustione della legna (forse aumentando l'aria in entrata-uscita per aumentare o diminuire la combustione). Quando si passa alla modalità RIS, limita chiaramente l'aria in entrata-uscita in modo che la legna bruci lentamente e si risparmi molta legna! A volte in modalità RIS può rilevare "mancanza di legna" anche se c'è molta legna, perché la combustione rimanente è troppo bassa e la temperatura nel camino/temperatura dei fumi è troppo bassa come quando non c'è abbastanza legna...

**-..Yes, in the manual it says that it further reduces the air intake.

• it almost always does the same thing to me too, in saving mode it tells me that there is no wood even if there is some, have you solved it? For me it is very annoying, furthermore if I try to open for a few seconds and close again without inserting any other piece or even inserting another piece of wood the wood reserve message disappears, it continues to burn but most of the time it no longer signals the reserve to me of wood, and tries to re-ignite it with pellets, it seems, if you think about it carefully, correct me if I'm wrong, that if the stove is in saving mode it doesn't sense when the wood is really running out and doesn't give the message (reserve wood) so much so that I was thinking of creating an alarm on Alexa using the wood temperature and smoke temperature sensor and when they drop below a certain temperature "simulate" the wood reserve message**

L'integrazione fornisce 2 diverse entità di potenza: una potenza a legna, una potenza a pellet. Almeno dovrebbe, dato che non sono aggiornato, forse un aggiornamento recente ha rotto qualcosa.

I don't see that

[vincentwolsink]

and isn't there a way to simulate this? this state (savings) is set when the thermostat is off....

You can put the stove in RIS mode with the external thermostat? I guess that would be the same as my stove going in ECO mode. I cannot manually put it in ECO mode, but once it reached the desired temperature it will do so automatically.

This integration is not a replacement for the internal (or external) thermostat of the stove. It allows you control just as with the remote or app. I bet you cannot put it in RIS mode with those either. (I would love to implement it for you, but the API doesn’t support it)

If you have a hybrid stove you should see pellet and wood power. Can you maybe send a screenshot?

For out of wood detection in RIS mode, we could hope that a firmware update from nobis could improve things in the future. My stove received a firmware update during last anual maintenance by my stove supplier, and i see correction and improvements on problem that i have indicated to them. I have one of the first unica A10 installed in France... (maybe the first one).

I also thought about using an external thermostat, but considering that i'll lose optimised logic (eco and ris mode) i gave up.
Eco could easily be simulated with an automation (switch off when reaching target temp for more than xx minutes, and switch on when temperature is bellow target temp minus xx degree for more than xx minutes)

For RIS mode is more complex as we could not set power to RIS.
What we could imagine is to use the stove logic only to go to ris mode : set target value as low as possible, set ris delay time as low as possible, and deactivate external thermostat.
To go out of RIS mode, just reactivate the external thermostat.
If i remember well, usage of external thermostat is exposed in a register. But don’t know if we could write it or is read-only.
If we could write it it will be possible to add it as a switch entity to activate/deactivate usage of external thermostat. All the rest could then be handled by automation.

I tried. I suspected it was exactly as you said.
however, it should be. I can set eco on the remote control. I can set a temperature to tell it when you reach that temperature then turn on the economy mode. But when you select manual mode it should be possible to put the economy mode manually.
I could ask, and I will, the nobis technicians if it is possible to implement the function. I have their email, and every now and then I write to them to ask for information, but above all an integration that I had asked for ever since I purchased the stove, namely integration with Alexa (the skill is missing), a lack which, ironically, led me to discover you, your project and home assistant (translated: without this gap on the part of nobis I would never have discovered the fantastic and magical world of home assistant and your project) to try to connect the stove to Alexa (and I succeeded thanks also to you).
But I was writing. I will ask, but given how much they listen to customers' needs I doubt they will. Here we have a saying that asking is permissible, answering is courtesy. and that asking is half the getting

I am in Italy, the supplier has also updated me, but the problem continues to exist, I have already tried, and it is the same. I will try to send an email to the Nobis technicians and see what they respond.

I also thought about using an external thermostat, but considering that i'll lose optimised logic (eco and ris mode) i gave up. Eco could easily be simulated with an automation (switch off when reaching target temp for more than xx minutes, and switch on when temperature is bellow target temp minus xx degree for more than xx minutes)

I use an external thermostat, I prefer it. I had already used it with the old stove and therefore I already had the system ready, cables and thermostat positioned in the center of the room. If I am not mistaken, the RIS function certainly also works with the external thermostat. I do not use the Eco (or comfort) because it does not seem to me to be a correct logic. the stove never goes into saving mode. or if it does, it does so for an insufficient time and with a correct logic. the right logic should be (and it is the one I will simulate with nodered: I am already doing the flow, it is very complex but I think I am right in the conclusion) the stove turns on if the temperature (I have a temperature sensor in the living room - in addition to the thermostat -) is less than 20 degrees, with power 3/4, when it reaches the temperature of 21 degrees it must go into SAVING (but since it is not possible, power 1) then if with the saving mode (or power 1) the temperature decreases or remains the same it remains on with those settings. otherwise if the temperature were to increase further up to 22 degrees, then the stove turns off and turns on again if it drops below 20 degrees, and so on. But the programming of the stove does not allow it and I have to do it with nodered.

For RIS mode is more complex as we could not set power to RIS. What we could imagine is to use the stove logic only to go to ris mode : set target value as low as possible, set ris delay time as low as possible, and deactivate external thermostat.

Forgive me but I did not understand you. perhaps Vincent is able to understand you and help us. The only switch I see is the auto mode.. but I do not think it can help us.. also because I have double ducting and it still works differently. Even if it is in saving mode, but the second duct fan is active, the power remains at 3 even if the remote control says saving, the only thing the stove does is turn off the front fan but the power remains at 3 because obviously the second duct requires enough power to let out hot air. I would like to force the stove programming instead in order to save on the pellet power and manage the fans as I like.

For the integration be able to expose an entity foe a functionality/sensor, the stove API must provides this data ("the register"). You can see examples by looking in "fixture" folder in the code of this github.
The integration does not use all of these data, only the usefull ones. And infirmation about external thermostat was not considered usefull till now.

I've checked the data exposed by nobis API for Unica A10 (could check fixture/nobis_hybrid) and there is a register concerning activation or not of exthernal thermostat. But it seems to be read only. I'll try to do some test tomorrow to see if i can write the register and how my stove react.

[merlino1975]

this way it seems to be clearer, even if, honestly, not being an expert programmer (I'm old and a beginner) I don't understand everything.
I think I understand briefly, without going into technical details, what you are trying to explain to me. And I would love to help you with this but I don't have the technical skills.
Having said that, what do you mean by activation or deactivation of the external thermostat? do you mean being able to manually choose whether the external thermostat should be in the on or off state... or just to choose whether to set the stove in manual or in "thermostat control"?
They are 2 different things.
And I can't understand what use it could be to be able as a home assistant to decide whether to use the stove manually rather than with the thermostat, unless when we want to heat the stove as we like we set it to manual and when instead we want savings (risparmio) we set it to "thermostat control" ...and we set the temperature of the external thermostat to a very low temperature so that it detects the temperature reached as always and sets the stove to saving (Risparmio). Bingo!!!!??

[merlino1975]

p.s. I sent an email to nobis assitance. I'm waiting for a response.even though I don't think they will. I have little confidence.

[jipem01]

By setting target temperature low, and deactivating the external thermostat (deactivating, not switch off), you fall back using the stove internal logic. As the temperature is low, the stove will directly go to RIS mode.
As long as we don’t have a command to force RIS it could be a solution to activate RIS.

[merlino1975]

bien sur mon ami

but... how can we do it? it is difficult to find an entity that allows the exclusion of the external thermostat
