If you have a bypass it should be set to auto not economy. The fan speed shouldn’t be set to medium, the fan speed should be set based on the amount of zones that are on really which is why intelligent auto exists. Medium can be too high at times and not fast enough for others.
If you want to DM I can send you my number and we can go over all with a quick phone call so you understand how all works and to setup the intel auto fan settings.
Thanks for all your help today, much appreciated. Can’t wait for it to get hot now so I can test the new AC.
Your very welcome!!
Hi Guys,
Is it possible for the AirTouch 5, or this software, to activate the ‘night mode’ feature on newer external compressors? We need this to help manage an external noise issue with our HVAC.
Background:
I’ve got AirTouch 5 installed in a new home we moved into about 12 months ago. We have a Toshiba VRF system downstairs running 5 zones, plus a seperate Toshiba unit running one zone upstairs.
The noise of our outdoor units has caused the neighbour to complain. So we had an acoustic consultant review and recommend a solution which includes a new thick fence, plus running the units on ‘night mode’ over night - designed to lower the power/capacity and noise.
Unfortunately the AirTouch 5 system doesn’t seem to allow the end user (me) to activate night mode (only the original standard controllers can). So the AC company installed a special module in the ground Toshiba VRF which forces the unit into night mode 24/7 (not ideal as it drops capacity during the day but best he could do).
However, he claims there is no module available for the upstairs unit.
Model Numbers:
Ground: Toshiba MCY-MHP0806HS8-E
Upstairs: Toshiba RAV-GM801ATP-A
I’m not sure about AirTouch support for night mode, but from what I can read of the wiring diagrams the night mode control is supposed to be via a switch/timer wired into the AC circuit. It shouldn’t have been hard-wired to be always on. It should be pretty easy to automate using a typical smart relay such as Shelly instead of a manual switch.
See page 42 of this doc for your downstairs unit: https://www.toshiba-aircon.co.uk/wp-content/uploads/2021/12/20210526_DB_E19-3B2-3_MCY-MHP_6HS8-E_8-10HP_EN.pdf
And page 4 of this doc for your upstairs unit: https://www.toshiba-aircon.co.uk/assets/uploads/pdf/eoi/TCB-PCOS1E2.pdf
(TCB-PCOS1E2 is referenced on page 86 of the service manual https://www.toshiba-aircon.co.uk/wp-content/uploads/2021/06/20210524_SM_SVM-18043-8_R32_RAV-GM_1ATP-E_56-140_EN.pdf)
The links are from Toshiba UK, but the model numbers are the same.
Hope that helps in conversations with your installer.
Hi all,
I’m new to this. Just had my ducted heatpump installed with AT5. Our living room ( spill zone) is always being overheat. I have read all your comments about this. Could you show me how to change it to economy on AT5? Is that better to have bypass installed rather then spill zone? Does the bypass cause any defects to the system at all? Cheers in advance.
In general, it does sound like a bypass is the best solution. However, like you, my installer set our kitchen/living room as the spill zone and it was being over-cooled in our case (as it was summer). I was lucky in that I was able to find another room in the house that I could make the spill zone. The room is just used for ironing, and clothes drying, is about the closest room to the return air, and the door is never closed and the air always has a path to the return air grille. As we are very infrequently in the room, it doesn’t matter if it over heats or cools on occasions. If you too are lucky, you might be able to identify a suitable room and the problem can be fixed by selecting and de-selecting a few options in the Airtouch.
Have messaged you
A bypass damper is the best solution by far.
I have a couple of automations that can reduce the overheating until you get a bypass damper, which I can put onto GitHub if anyone is interested. Airtouch tends to close the dampers much earlier than I think it should, so that most rooms don’t go over the target temperature. When the room is really close to temperature it can sit with a room damper 5 - 15% open for 10 minutes or more, which means the other 85 - 95% of your heat pump output goes to the spill zone.
My automations keep the room room dampers open wider for longer, then shuts the damper down when it’s near the target temperature. Previously in heating mode our spill zone would overheat by 2-4 degrees, these days it rarely overheats at all, occasionally it might go over by 1 degree.
I’ve noticed the same behaviour. Would be curious to see what your automations look like. I’m about to start tinkering with one of the PID components from HACS to get the room to set point or slightly overshoot the target as quickly as possible, before switching back to temp mode on the AT5.
I’ve updated my GitHub repo with with my latest HA automations. Please read all the readme files, there’s some important notes in there, such as how I detect the outdoor unit state which turns out to be important for some automations.
I’m pretty sure others will be able to improve these automations, but they work ok for me.
Hi all,
Im new to HA and keen to get my AirTouch 5 with Daikin ducted AC new about a year ago set up but i’m stuck at the first step… I keep getting failed to connect when trying to enter 'host; what exactly do i need to enter here as previous comments show this was called Host or IP Address? I have the IP from the tablet but no luck. I’m running HAOS on an old mini PC so don’t think there is any firewall to block it.
also thanks to those who have mentioned the wifi dropout issue in here, it’s been driving me nuts, i’ll get the installers back out.
It should just be the IP address of the main AirTouch tablet on the wall. Perhaps check to see if you can ping the tablet IP address from your Home Assistant PC.
If you’re using the built-in integration, you could also take a look at my HACS integration as an alternative. It will automatically discover the AirTouch console on the network without needing to enter the IP address (just like the official AirTouch mobile app). If the auto discovery doesn’t work, that usually means there’s a network connection issue.
The IP address should look like “192.168.1.55” or similar. Nothing else, no speech marks. You should check there’s no firewall on your network blocking the connection. You can find the IP address if you go into the tablet’s desktop, click on the WiFi, and poke around in there.
It can be helpful to set a static IP for your Airtouch tablet. This is router specific, but if you search for your router model plus “DHCP reservation” you should find instructions.
Thanks yes that’s how i previously got the IP address but it still couldn’t find it. I will try setting a static IP and see if i can ping it to check for Network issues, not sure what would be blocking it though.
@TheNoctambulist I updated Home Assistant Core to
2025.4.4 last night and now for some reason, the AirTouch service isn’t firing up (tried a full reboot too).
The logs show:
Logger: homeassistant.helpers.frame
Source: helpers/frame.py:335
First occurred: 07:40:19 (1 occurrences)
Last logged: 07:40:19
Detected that custom integration ‘airtouch’ sets option flow config_entry explicitly, which is deprecated at custom_components/airtouch/config_flow.py, line 256: self.config_entry = config_entry. This will stop working in Home Assistant 2025.12, please create a bug report at GitHub · Where software is built
Is this something you’ve seen and know how I might resolve?
Shall I raise as an issue in GitHub?
That deprecation warning shouldn’t cause any problems until the end of the year, but I will release a new version soon to address that.
I haven’t upgraded my main instance to 2025.4 yet, but I just tried the integration in a test instance of Home Assistant and it all seems to work ok. I’m happy to take a look at the debug logs to see if there’s something specific on your system. You can turn on debug logging from the main AirTouch integration settings page.
That’ll teach me to rely on software… AirTouch had dropped off my wifi and so HA couldn’t connect. Apologies for any confusion 
At least it’s sorted now.
If the wifi drop outs are happening regularly you should submit a support request with Polyaire for the console update. There’s a few related discussions earlier in the thread.
I’d like to get some more detail on this wifi issue if possible.
We get the issue every now and then where the app and HA can’t connect and when I look at the tablet it is offline.
If I go into the Android settings and try to turn wifi off or on it doesn’t work. I don’t mean it won’t reconnect to my wifi, but that I can’t actually turn wifi on or off - it seems like the whole wifi system on the tablet is frozen.
To fix this I need to reboot which fixes the problem (for a while).
I have just had a conversation with someone at Polyaire about it to see if this is the issue but they seemed more concerned about making sure my wifi was 2.4GHz and not a mesh network. I don’t think this is the issue though because if it was just wifi connectivity I would imagine I could still turn wifi on and off but it wouldn’t connect - as opposed to not even being able to toggle wifi on and off.
If someone could confirm that the behaviour I am seeing is caused by either the security patch or my network setup that would be great.
I looked back through this thread and found this post about the security update version so figured I would check that, but this post says the problem is with the October 2022 version and mine is 5 May 2022. Does anyone know if this version also needs the SD card patch?
Thanks all
