I’m going to be integrating Amazon Alexa with Home assistant.
Firstly, I’d like to ask is alexa integrating with home assistant or home assistant integrating with alexa?
Secondly, I have a few echo devices, so my question is should I connect zigbee devices to echos and then integrated alexa with HA. Alternatively, I also have mqtt running so should I connect zigbee devices to mqtt? Which method is easier, better?
Third question kinda links in with the second. The zigbee devices which are connected to alexa, will they show up in HA? If so should I leave them be, or connect them to mqtt? Is there a benefit either way?
You really need to integrate it in both directions for full control using two different approaches. To integrate Alexa into Home Assistant, the best way is the Alexa Media Player custom component:
This will bring your Alexa devices into Home Assistant, so you can control their volume, do not disturb settings, routines, and make announcements using text to speech through them.
To integrate Home Assistant devices into Alexa in that direction - ie you tell Alexa to turn a Home Assistant connected switch on, the best way would be Home Assistant Cloud aka Nabu Casa and the Home Assistant Alexa Skill
No, they will be difficult to control that way and cloud dependent. You ideally want to get a zigbee USB stick, and then bring your zigbee devices into Home Assistant using ZHA.
Or if you need advanced options and want mqtt, zigbee2mqtt.
If you have Home Assistant cloud, your zigbee devices integrated to Home Assistant would then be connected to Amazon. There is a small monthly fee for the cloud, and initial one time fee to buy the zigbee stick (recommended ones here Supported Adapters | Zigbee2MQTT ) - but to get local control of the zigbee devices it is worth it.
If you use the Amazon device as your zigbee hub, you could control the zigbee devices by setting up Amazon routines and using the Amazon Media Player skill to trigger those routines to turn those zigbee devices on and off, but you will not get status of those devices in Home Assistant. For example, if you turn it on through Home Assistant, but you turn it off through Alexa, Home Assistant would have no idea if the switch/device was on or off. Therefore, I wouldn’t recommend trying to integrate zigbee devices directly connected to Alexa to Home Assistant.
is there a way to bring the Alexa sub-devices to HA, not only the Echo speakers?
I have a radio frequency “blackout internal curtain” (Mottura brand), controlled via Alexa with a Broadlink RM4 Pro + that I would have into HA.
I have an Amazon branded Smart Plug I can control this way. However, as I mentioned above, you can’t get the status of any device this way - you can just trigger the routine to turn it on or off, and it is cloud dependent. No internet, or an Amazon cloud outage, and it won’t work
I think i have a similar situation and i’m not exactly sure how to succeed in controlling HA zigbee devices through Alexa voice commands.
I already have Alexa Media Player running and also have my HA accessible through the cloud (not Nabu Casa, the other painful way).
Real situation: I have 20 devices connected to HA zigbee network using the skyconnect dongle. I want to be able to control them through alexa voice command, like “Alexa, check if all windows are closed” or “Alexa, turn on the coffe machine Plug”. Is this possible to do using only what i already have installed? Do i need to create a service/entity to be accecible by Alexa to all these devices?
Thanks in advance
If not using Nabu Casa these are your options for setting up Alexa control of your devices under the “manual setup” entries. You basically need to create an Amazon web developer account and your own skill, which is difficult.
As an alternative to that, and what I use, is an integration through Node Red. There are several, and I use node-red-contrib-alexa-smart-home
