How is this possible?

[seydx]

I recently see a video of a valve(?) service with following ui

Is this currently possible? Or is this a special version of HomeKit?

Here in action: https://m.youtube.com/watch?feature=youtu.be&v=D6FzNLDbw5Q

I tried to create a valve service or faucet service with additional current/target temperature characteristics etc.. no chance

Any idea @KhaosT ?

Best regards

Linked services I assume

Ah... wow! I was wondering what the usecase of Characteristic.ValveType.SHOWER_HEAD would be. But not sure, how you can get this to work. Maybe it’s similar to the irrigation system. You may need a Service.Faucet and a Service.Valve for each shower head (with ValveType set to SHOWER_HEAD) linked to the Faucet service. But it‘s still a guess. I‘m not able to test this out for the next week.

For the temperature it might be a Service.Thermostat or just a Characteristic.TargetTemperature. Since TargetTemlerature is not defined as an optional characteristic for Faucet or similar, I suspect it‘s a service.

Unfortunately there is no HAP documentation out there, that states which combinations of linked services are supported.

So, i tried many combinations with different services als linked service and characteristics... I cant get the temp slider... other things like the shower heads is no problem, but how can i get the slider....????

[seydx]

As "Main Service" we need the Service.Faucet and we need to add Service.Valve as linked services with different subtypes to the Service.Faucet

It is possible to add multiple Service.Valve to Service.Faucet

Because of slider i tried adding Service.Thermostat as linked Service and Service.TemperatureSensor

I tried also different characteristics on Service.Valve and Service.Faucet like Characteristic.TargetTemperatureand Characteristic.CurrentTemperature, but the temperature slider will not appear...

I finally made it!

Have to test something, will immediately post an instruction

Ok guys, i think im ready..

• First of all, you need to add a "main" Service. In this case it is Service.Faucet
• If you want to adjust the temperature, you need to add at some characteristics to Service.Faucet
• These are: Characteristic.HeatingThresholdTemperature, Characteristic.CoolingThresholdTemperature (you dont need to add both, one is enough) AND Characteristic.TargetHeaterCoolerState(this one is important, otherwise the slider will not appear)
• The "icons" are Service.Valve. It is possible to add multiple valves with different types (shower head, generic valve, faucet) but you need to give them unique subtypes! All of these can be disabled under settings and are summarized as "Shower Heads" in the settings.
• It is also important to set Characteristic.ServiceLabelIndex for the valves ! (1 for Valve 1, 2 for Valve 2 etc.)
• To add names, you need also add Characteristic.ConfiguredNameto these services, otherwise all Service.Valvewill appear as Faucet 1, Faucet 2, Faucet 3 etc...
• After adding these extra services, you need to link them to the main service Service.Faucet

It is possible to trigger all added valves at the same time, but at least one of them must be "InUse" (InUse = 1 / Active = 1) to activate the main Faucet, otherwise it will loop at "Starting..." - Also for disabling the main Faucet, all extra valves need to disabled (InUse = 0 / Active = 0)

A short summary for Active / InUse - Logic:

Active=0, InUse=0 -> Off Active=1, InUse=0 -> Waiting [Starting, Activated but no water flowing (yet)] Active=1, InUse=1 -> Running Active=0, InUse=1 -> Stopping

(thx to @tobekas for the short summary)

Nice! I wonder if there are even more combined control elements available in Home. Would be also useful for multiple lightbulbs or switches...

@SeydX. Can you post a file with the code? @tobekas - I was wondering the same thing about multiple dimmers. For example, in my kitchen, I have 4 dimmers to control lighting. Could they be linked so they show up as one device but with 4 sliders on its main page? If you find out anything more, let us know.

@jvmahon

yes, im implementing it to my tado-platform plugin but with only one valve

• To add names, you need also add Characteristic.ConfiguredNameto these services, otherwise all Service.Valvewill appear as Faucet 1, Faucet 2, Faucet 3 etc...

Interestingly, using this idea, I added that characteristic to my "sprinklers" in my irrigation system. Seems you can have an on.('set' event bound to that to get notified of the name changing in the Home App. awesome

[tobekas]

I found this header file with some very interesting comments in it for the usage and combination (linked services...) of the HAP Services: https://github.com/MrAB-AbhijeetMahashabde/Quectel_BG96/blob/c97440947309d13c41c5cc55919413fa2c1847e9/Apple_Homekit/HomeKit%20ADK%202.0/HomeKit%20ADK%202.0/ADK/HAP/include/HAPServiceTypes.h

Especially the use of IrrigationSytem and Faucet (with linked HeaterCooler) is well documented there.

[tobekas]

@SeydX: So it seems to be better to put the temperature characteristics into a linked HeaterCooler Service for this Shower system.

@tobekas Thx for the link!

Im reading the hap r13 pdf and there are all informations we need to build these accessories... there are also informations about tv accessories and some (new?) characteristics like siri etc

https://github.com/MrAB-AbhijeetMahashabde/Quectel_BG96/blob/c97440947309d13c41c5cc55919413fa2c1847e9/Apple_Homekit/HomeKit%20Accessory%20Protocol%20Specification%20R13.pdf

@KhaosT maybe something for homebridge here?

[KhaosT]

As of right now there is no plan to implement support for remote control profile, since that's a really useless profile... Just use Siri Remote for that 😅

Doesn't work atm like this in IOS 13 (beta2 and public beta 1). Just shows the on/off switch without the temp control.. See how it goes in future betas

I tried to download that R13 HAP specification, but no luck. Is there a new link to it?

Apple was pretty quick in removing it. As it should only be accessible to people with an Mfi license agreement. Only the non-commercial version from few years ago is publicly available.

You can find the file here

I wrote a plugin for a custom outdoor shower which I made using two sprinkler solenoids and a Raspberry Pi. This thread was really helpful in writing the plugin. I'm curious though, has anyone been able to use Siri to set the temperature? I can use Siri to turn the shower on and off but when I set the temp, Siri responds saying she did it but the slider doesn't actually move.
