It looks like Delta killed an access to the : https://device.legacy.deltafaucet.com/
Starting from today my Delta Integration abruptly stoped working.
What use to be a web based faucet control web page is not accessable anymore.
This was only one left cloud-based integration and it is gone.
I think it is still possible to use Alexa but now it will be two cascaded clouds.
Cloud-based based integrations may stop working at any time. This happens left and right. And this is a MAJOR reason why I am no using any cloud-based services. Only brainless people thinking that puting in the entire Internet infrastructure between light bolb and wall switch is a very bright idea. But it is what it is.

Are you sure the access is down? Your link works, but I assume you mean the API access no longer works despite the webpage being up.
I can't find anything that says they discontinued their APIs. Is this just one of those issues like needing to go on their app and accept the new terms of service or something?
My module died last week… They sent me a new one which I haven’t setup yet, but I expect that our Hubitat integration won’t work anymore…

Webpage was inaccessible for the entire day. I have no idea when it became inaccessible because I did not use it for about a year. Surprisingly now it is up but I cannot login. It says the account does not exist.
Searching the web for the link to this page did not yeild anything. This led me to think this service/api is discontinued.
However and to my big surprise the integration woke up and became functional. I am sceptical. My good guess plus taking in account info what I collected this integration may die very soon.

Unfortunately this could be a case.
So you just reached out to them and they sent a new version of the module? I have version 1, so I wonder if I could just request a new module. Did you have version 1, or version 2 previously?
What version module did they send you for replacement, and does it still work with the integration you created?
I have the version 1 module, and while it's still working, every so often it just doesn't dispense to correct amount anymore. Doesn't matter if I'm using the Hubitat integration or the Alexa integration. When it isn't functioning properly, it will just keep filling beyond the requested amount. Odd thing is, the next day it will work fine. 
It smells like impeller experiences some exra friction.
Maybe a good wash (i.e. running at max flow for 10-15min) could fix the problem.

I had a version 1, and I called them to see if they could help me find a way to make it work again… Their solution was to send me a new one. I just installed it, and it is a version 2. Not sure if there’s much of a difference though the install steps are different in the app.

Thanks. I am having occasional trouble as I mentioned, so I will give them a shout and see if they’ll help me in the same way.

Just got this in my inbox. Assuming you guys got the same message?
YOUR VOICEIQ FAUCET
IS GETTING AN UPGRADE
To continue enjoying full functionality of your VoiceIQ faucet, be sure to download the DFC@Home mobile app. Starting December 29, 2025, the current VoiceIQ website will be shut down, and the DFC@Home mobile app will be the only way to set up or configure your VoiceIQ faucet. Using the DFC@Home mobile app ensures you get the most out of your smart faucet experience.
DOWNLOAD THE DFC@HOME APP NOW
Yup, an « upgrade »… not sure they know the difference between an upgrade and a downgrade…

Yes, I just got the same email notification.
It means the HE Intergation will be dead very soon. My setup already experienced periodic failures few times a day. Attemp to login to : https://device.legacy.deltafaucet.com/
failes with messages: "No account located with these login credentials". So, the original website is already locked for the user login.

Yes, this is correct. And they are let say this way "not smart" not to provide an open API. Ideally they should/must provide an API for the local control and keep these cloud-based integration as a secondary choice or for those who likes the use the entire Internet infrastructure for very simple things. My strong opinin is - clouds are not welcome for the REAL Home Automations.
This inspired me to reverse engineer (hack) a connection between VoiceIQ and Touch2O modules. Wiring is a standard RJ45 Ethernet connector but I am 1000+% sure the signaling is something else (hopefully it could be a staright On/Off control or RS232/SPI somple mesaging). I was thinking to do this long time ago but was too lazy to actually do this. Now it is a righ time to get everything under local control.

Interesting… I suspect that module also does the flow control, so ideally, we would be able to decode its wifi traffic to reverse engineer its API…
Flow Mesurement and WiFi connection is handled by VoiceIQ Module (that is why it has a water connection). Flow Control (i.e. Solenoid On/Off) and Capacitive Touch Sensor is handled by Touch2O Module. VoiceIQ measures a water valume and simply sends On/Off commands to the Touch2O. Physical Interface between these 2 modules is RJ45 Connectors and short standard Ethernet Cable. However the Logical Interface is something Delta proprietary and has ABSOLUTELY nothing to do with Ethernet. First step will be to decode (hack, reverse engeener) a communication between these two modules. I hope, this will not be a difficult (but will not be easy) task. Let me see, how this will go and what I will find out ...

Many years ago when it was nessecary, there was a method to use Charles to obtain tokens. I wonder if it might also be possible to do this with the DFC@Home app.
Mybe. But I "love" clouds so much so I will try hard to get rid of this one as well.
I'm all for a hardware solution if you guys can come up with a viable one, but I like a quick fix if it'll give me back what I have today (which has been working very well until this change).

UPDATE.
I have a Good News and a Bad News.
The Good News is:
Interface between Touch2O and VoiceIQ modules is successfully reverse engineered.
The communication is RS232 , Speed is 9600b/s and levels are 3.3V. In addition to the serial link there is a by-directional line for handshaking between these two devices.
The DIY Hubduino (again big thanks to @ogiewon) already designed, debugged and veified. Of course, the ingration with HE is 100% local. The supported commands are "Open Valve" and "Close Valve". Status is correctly reported to the HE when Valve is controlled either manually or via commands. Water Temperature could be monitored but not implemented. Frankly I don't need temp monitoring so I am not sure I will add this option.
Next step will be to put everything together and find a nice small case (maybe 3D printed).
The required hardware is any ESP32 Development Board, small 9V to 5V DC Downconvertor, RJ45 Connector and a sutable Case. Very minor soldering skills are also required.
If anybody interested in reproducing this comtroller I can share a Hubduino Code. The HE Drivers already exist.
The Bad News is:
VoiceIQ Module cannot be reverse engineere and reprogrammed. Everything is encrypted and hardware is locked for reprogramming. But frankly I don't care. My use case for the VoiceIQ module was only to Open/Close Valve via commands. Now I how ESP32 doing this things.
Bottom Line:
Bye, bye Delata Cloud-based integration.

This sounds extremely interesting! Do you add the ESP32 between the VoiceIQ and the Touch2O?
Why I’m asking… my wife and I love the ability to request a certain quantity of water from Alexa. Is this still possible with this solution?
