Clarification regarding commercial use of home assistant compatible devices

Thank you very much for a quick response. And forgive the confusion between the two.

If I want to make a device compatible with google home / alexa, I must have a smart hub which runs home assistant. A home assistant will be able to control smart devices through google home or/and alexa speakers. Is my understanding correct here?

Also, if I have a hub, I can set it up with my smartphone so I dont even need to have a alexa speaker and can just tell my phone to turn on/off the appliances?

Thanks in advance.

If you are asking if HomeAssistant can act as an intermediary between devices that are not google/alexa compatible, and a smart speaker from google/alexa, I believe the answer is yes, if it is configured properly.

The phone companion app talks to HomeAssistant and gives you an interface, I do not know if there is voice control built in.

On your first post, you mentioned:

No.

Could you elaborate on that a little please? How can I automate without a hub?

Also, allow me to clarify “If you are asking if HomeAssistant can act as an intermediary between devices that are not google/alexa compatible, and a smart speaker from google/alexa, I believe the answer is yes, if it is configured properly.”

I will give an example. I have purchased a google home hub and I have microcontroller ESP32 which is running MQTT to toggle on/off the lights. I will need to “add” this device to my home assistant service and configure it before I can toggle the lights, also will need to program the microcontroller properly to send the required mqtt packets. Is that correct?

There are many ways. The ESPHome or other integration specific API that works via wired or wireless network. Restful sensors, MQTT, and too many more to list.

Okay thanks. I am mainly concerned about google home and alexa since I want my product to be compatible with those. In that case, a user will need to have its hub to use my product.

Hoping to get some clarification regarding developing product for commercial use which is compatible with smart home hubs such as google/alexa

No they won’t. Why would a hub be required to talk with Google Home?

All you need is Home Assistant. It connects directly to Google Home via the Ethernet Network.

Same for Alexa.

Then you are in the wrong place. This is a Home Assistant forum.

Now I am slightly confused. I thought the hub is necessary to direct the remote commands from the google home to my smart device, isnt that right?

All you need is home assistant - thats what I assume is hub for. hub = home assistant. Is that not right?

To be honest I’m having a hard time understanding what you are saying.

Home assistant can be considered a ‘hub for hubs’. i.e. it allows control of devices connected to one hub by devices connected to another hub. But Home assistant itself can talk to many devices directly without a hub using many different protocols and APIs.

Home assistant is nothing to do with Google assistant

Well I assumed that the most average customer is not going to have a “custom” raspberry pi home assistant built in his home. I assumed that most people will be using a smart home hub such as echo hub or google nest hub. This hub is already running a home assistant service and they would need to “configure” it slightly to connect to any smart device that supports required protocols.

Then as I said, you are in the wrong place. This is a Home Assistant forum. Everyone here has Home Assistant.

This is not the place for advice on developing for Google Home or Alexa. It’s the place for advice on configuring and using Home Assistant the product:

Not home assistant the generic term for all hubs and such.

Okay I think its getting clear… I was under impression that most smart home hubs use home assistant service to automate devices.

Those devices are not running, and cannot run, Home Assistant. They are running a service that you can describe as a home assistant, but not this Home Assistant which is unrelated to the Google and Amazon services (although it can be configured to take advantage of them).

Okay thanks for clarifying… And I appreciate your patience.
So if a person have google nest hub setup at his home, he will be using google assistant?

If a person is using amazon echo, he will be using alexa.

but what is common between these two, that in order to automate their home, they both need Home assistant service which routers all the commands to the required smart devices? Am I getting close to understanding how it works?

Getting closer but not close enough to be developing any products I’m afraid.

As long as im getting there

Nothing (edit: well maybe HomeKit is common between the two).

The Home Assistant developers have implemented two different API’s to communicate with each of them.

Most people that have a Google home hub have a few devices they use it to control. Usually this control all works via the cloud, each device maker has to provide and maintain cloud access for their devices.

Im trying to understand what he meant by saying home assistant connecting to google home or alexa. Could you guys clarify please?

I am trying to learn and understand what is the exact purpose of home assistant when a person is using google or alexa automation in his home. Does he even need to use home assistant and for what purpose. I am reading more and hopefully can come up with better and more clear questions… sorry

No. Not at all. If you buy all devices compatible with Google Home.

Then you can do some simple things with just Google home like telling it to turn off your lights or to order 13 metric tonnes of creamed corn using your voice . It’s a fancy remote control.

However if you want your TV (that is not compatible with Google Home) to come on only when you are home and it’s the day before your soccer practice and rain is forecast and it’s time for the local weather report - then yeah Home Assistant is good at doing things like that. Google? Not so much.
