Is it possible to activate "Continuous Fan" mode? #143
Comments
Hi. Glad it's working well for you. Does the OEM app have the ability to control this feature? If you enable debug logging, and then toggle this function on and off while waiting about 30 secs between we might be able to determine which bit controls it. |
Hi @mill1000 I have 2 Toshiba AC units with the same continuous fan mode option by holding the fan button on the AC unit. The OEM app does not appear to expose this option. I turned on debugging, toggled the setting on the unit, waited 30 sec, then toggled again waiting another 30 sec before turning off debugging per your info request above. Is there anything specific to look at in the log to tell if the option change/toggle was sent to HA? The properties response payload does not change, but the state response payload changes (not sure if those are even related to what you are looking for). I can attach the log if you would like to give it a look. Thanks! |
Hi Jason. Please attach the logs. The state response will hopefully contain the information we want. |
Here ya go. The IP of the AC unit I was testing with is: 10.8.5.127 Edit: I forgot to say that the AC unit already had the option turned on, so hopefully the data in the logs would show turning the option off, then back on ~30sec later. home-assistant_midea_ac_2024-06-26T18-46-56.719Z.log If you need anything else just holler! |
Cool. The only bit (beside temperature) I see changing in the state responses is the ECO mode bit. Have you noticed if ECO mode turns on/off when in continuous fan mode? |
There is no ECO indication light or label on the AC unit its self, and I can not find any mention or indication for an ECO mode in the Toshiba/OEM app. What I have observed with the option turned off is the inside fan, outside fan, and compressor will all cycle up and down regardless of the specified fan speed (almost as if the specified fan speed is the max speed the inside fan could run at). When the option is turned on the inside fan stays at whatever speed is specified, then the outside fan and compressor will cycle up and down as needed. And just to specify, the inside fan is the fan that circulates the conditioned air. |
Hello! My apologies, I missed your reply in my inbox. The same with SomeJ0192, there's no ability to enable the option through the app, although I've just captured the logs, I enabled logging, waited 2-4 seconds and pressed and held the fan button to toggle continuous fan mode, waited 30 seconds, pressed and held it to toggle continuous fan off, waited another 30 seconds and then stopped logging. Furthermore I cleaned up the log file a bit to remove anything that wasn't msmart or midea related as there was a lot of unrelated entries from my tplink devices, mqtt and other items. I hope this helps to give a bit of information from one of my Mideas too. |
@SomeJ0192 Does Home Assistant show the ECO preset being turned on?
@quentinwolf No worries. Thanks for the logs. There are multiple devices in this log, do you know which device you tested on? |
192.168.100.115 looks to be the one I did the tests on. Comparing the MAC address on the unit to the one assigned to that IP address in UniFi shows IP 192.168.100.115. I had a bit of confusion as I had swapped the 2 AC's around (one being an AC only, the other a Heat Pump model with the ability to heat. Moved the heat one upstairs and AC only downstairs) but forgot to rename them in UniFi. |
Judging by the features, I'm confident the Toshiba model that SomeJ0192 has is likely a rebranded/identical model to my Whynter and Danby models. Would be awesome if it could be toggled based off of some little flag, but if not the manufacturer likely just never exposed that to the module in the unit (which would be silly because the ability to turn continuous fan on or off is definitely a nice feature to have to use it to keep circulating the air in the room around.) |
Did some digging with msmart-ng and it appears the different speed settings are coming from the AC unit. Also it is reporting ECO mode as not supported, yet based on the debug output the units are changing the ECO mode bits when enabling/disabling the continuous fan mode (more data further below showing this via general querys).
Query while continuous fan mode is turned ON. note how eco is set to false
Query while continuous fan mode is turned OFF. Note how eco is now set to true.
It appears the unit is reporting as not supporting an eco mode, so my guess is the HA module does not present the option. However it does have an eco flag/variable that is being used by the "continuous fan" mode. Maybe the module could check to see if the eco variable exists even if eco mode reports as false, and if the variable exists then give us an eco (or in our case a "continuous fan") toggle button. |
Yes this is expected. There seems to be some inconsistency between models on what "high" speed should be. Here's some history on that mill1000/midea-msmart#95 and #67 What I should really do is probably expose an option to allow users to customize their fan speed values (when custom speeds are supported) The value of 102% for Auto is also an artifact of how it's encoded. I provided some details here: #96 (comment) It's occurred to me that the fan entity may be a better approach than the number entity for custom fan speeds. I could use the preset feature to better show Auto functionality but I'm still limited by the fact I can't query the actual fan speed to display it properly.
Yes is appears that "continuous fan" is the opposite of ECO. Your units default to ECO, while other units default to "continuous fan".
@SomeJ0192 Can you clarify that part about HA can't enable any other preset? Do you mean it fails to switch out of ECO, or just that you can't select multiple presets (which is expected)? |
Another user had a similar model of Whynter ARC-1230WN, which also had some odd ECO behavior. I don't think we every really got to the bottom of it: #130 |
HA fails to switch out of ECO (set eco to false) so there for it is not enabling any other preset. HA is also unable to set ECO to true, but it will set any other enabled preset to false in the process. For instance, if the boost/turbo preset is true, trying to set the preset to ECO with HA will set boost/turbo to false, then fails to set ECO to true, so the preset mode then displays as "none". (I failed to specify that in my last reply) Is it possible to put in some kind of override option to not treat the eco preset variable as a preset if the unit does not report an eco preset option (IE: 'supports_eco_mode': False)? |
Could capture logs of this occurring? |
Sorry it took so long to get back to you with these logs. The wife got me busy on other things and I finally found time to sit down and work on this again. All of this testing is with the all presets flag enabled. I am using msmart-ng to verify settings changes. This log is with ECO set to false (cont. fan on) and boost/turbo to true at the start. I used HA to turn on ECO, in the process it set turbo to false, and then failed to set ECO to true. HA will show the preset as "none". It appears that I might have been mistaken about HA not being able to make changes while ECO==true. I've been testing this for a bit and its acting very strange. I need to step away and let my head clear so that I stop over thinking it and to work up a test procedure that I can reproduce. In a nut shell, what I am observing while ECO==true, some times when enabling turbo it will not set the flag to true, some times when enabling sleep it will not set the flag to true. But some times it will set the corresponding flag to true properly. There appears to be a some what specific order of preset selecting that determines if the flag gets set properly or not. Also HA may not always show the preset properly, IE i might have selected the sleep preset, msmart-ng says sleep==false but HA still shows sleep as being active and the unit sounds like it is in sleep mode. ---Keep in mind this really odd behavior only happens while the show all presets flag is enabled--- While the preset is showing boost or sleep, but the corresponding flag shows false, setting the preset to ECO does nothing, but then setting the preset back to the desired setting then properly sets the preset flag via msmart-ng. Im not sure we should focus too much on this oddness as it only presents when the show all presets option is enabled and ECO is set to true. (at no time was HA ever able to actually change the ECO flag from true). |
Somethings to keep in mind.
The combination of 2 & 3 may cause an apparently lag in the device state if/when settings are changed rapidly. |
Hello there!
I'm still loving your integration, it's been working well for me, although I do have an inquiry that I wasn't sure about. I have both a Whynter ARC-1230WNH (With Heatpump capability to provide heat), as well as a Danby DPA120B9IBDB-6 (an almost identical model as the Whynter, minus the heat mode), both appear to be based off of, or rebranded Midea Duo Smart Inverter models, so they both have been working great with your integration.
My question though, is both of them allow you to press and hold the Fan Speed button on the unit for 3 seconds to toggle "Continuous Fan" mode in any of the available modes (Fan/Cool/Heat). If you have the fan speed on "Auto" and activate the Continuous fan mode, it will continue to ramp up and down depending on cooling capacity required in the room, but once it reaches the desired temperature and goes idle, the fan stays going near silently but still moving the air around which is nice (along with the louvre fanning up and down), vs not having Continuous activated (once the machine cools the room it turns the fan off completely and sits idle for a period of time before turning on the fan briefly to check the temperature of the room and then either enable the compressor to further cool the room down, or turn the fan back off again if the rooms temperature is stable, which I find kind of annoying.)
I'm just curious if it's possible to toggle the continuous fan mode via your integration? It doesn't seem to be possible to do it from the IR remote control, as pressing and holding the fan speed button just moves it to the next fan speed up and otherwise doesn't do anything else.
Thanks for your time and for the improvements and continued support of the integration!
