"ReSpeaker Lite" - new Seeed Studio Voice Assistant Development Kit hardware combine ESP32 with XMOS XU316 DSP chip for advanced audio processing as a ESPHome-based Home Assistant Assist Satellite voice devkit

I also added in LLM initial promt something like this “If you are expecting a follow up response, always put a question at the end of the last sentence.” This unexpectedly caused the voice assistant to ask if I needed anything else after answering my question or performing an action. This way continuous conversation works quite well

I’m having serious doubts that I installed the dfu_firmware_48k_v1.0.9 version and NOT the v1.1.0 but now I can’t check if it’s going to happen in 10 days… does it change much?

formatBCE · May 29, 2025, 9:43pm

I don’t get you. Why 10 days?
1.1.0 has much better mics.

Skyman1 · May 29, 2025, 9:48pm

because I travel for work…

formatBCE · May 29, 2025, 11:03pm

Ah… sorry, i was a bit confused
Well newest ESPHome firmware should install 1.1.0 automatically on boot, if it’s not there.
Lately though there were some reports from users, that they can’t flash the board - faulty batch…
You may check the installed DFU version on device page, it has DFU firmware sensor.

I have three of these Respeaker Lite voice assistants and I was trying to group them as media players however when using the group media player only one of the them will actually play instead of all three. Is it possible to put these into a media player group and get them all to play in sync? Has anyone been able to do this or used another method?

Not yet unless you add some other third-party custom component client as player provider that support that, but ESPHome and Music Assistent developers working the Open Home Foundation have said that they are have started worl on a new protocol that will add such capabilities, see replies to this feature request here (which IMHO should not have been closed yet) → [REQUEST] Add ”audio synchronizer” feature to Audio Media Player for synchronization between multiple ESPHome media players for synchronized multi-room music playback · Issue #3157 · esphome/feature-requests · GitHub

**Describe the problem you have/What new integration you would like** Feature …request look into adding some kind of ”audio synchronizer” feature to support Audio Media Player synchronization with microsecond timestamp accuracy between multiple ESPHome media players for synchronized multi-room music playback. The goal is to achieve synchronous multiroom audio playback for music using client-server audio player, where all clients (media players) are time synchronized with the server to play perfectly synced audio. Multiroom audio (a.k.a. distributed audio) with a such ”audio synchronizer” feature for synchronizing music playback on multiple speakers is a key feature of competing voice assistant / smart speaker echosystems. Suggest maybe look into [rwrozelle’s Audio Media Player code for ESPHome](https://github.com/rwrozelle/audio-media-player) which has an implementation that allow other audio media player members to join a group and then the group members will turn off, turn on, set volume, and play the same media as leader. Synchronization is attempted by telling leader and group members to start media at the same time. Uses the Time component in the sntp platform to assume that chips have the same time. See: - https://github.com/rwrozelle/audio-media-player **Please describe your use case for this integration and alternatives you've tried:** As far I know there is no good open standard(s) available that can achieve this with existing fully open-source audio protocols for music streaming in ESPHome [kahrendt](https://github.com/kahrendt) did however recently write that ESPHome developers are in the early stages of adding some kind of synced audio support to ESPHome as a general feature (for the "Resonate Audio Protocol " / RAP or "Chicago Audio Protocol" / CAP?), but that it is in the early stages. One task related to it as available in the backlog of the ESPHome project board -> https://github.com/esphome/backlog/issues/20 * https://github.com/esphome/backlog/issues/20 **Additional context** Spotted that ([kahrendt](https://github.com/kahrendt)) already implemented a lot of related new media player features which was recently merged into upstream ESPHome, like: - https://github.com/esphome/esphome/pull/8164 * *Adds a playback duration callback to the parent speaker component (and implements it in the i2s_audio speaker component). This precisely tracks the audio duration written to the DMA buffers to potentially enable synced playback in a future update.* * *Adds pausing to the parent speaker component (and implements it in the i2s_audio speaker component). This will reduce latency when pausing the media player when several virtual speakers are stacked.* and - https://github.com/esphome/esphome/pull/8171 * *PR9 adds a new speaker media player component that sends audio to another ESPHome speaker component. It supports two pipelines, one for announcements and one for regular media. Each pipeline requires a unique output speaker. Use a mixer speaker from https://github.com/esphome/esphome/pull/8170 to create two source speakers that are mixed and sent to another speaker component.* * *To increase the number of audio formats available and to minimize the load on the ESP32, you can use HA to transcode audio automatically before it is sent to the device. By default, it transcodes to FLAC, which uses the CPU the least. You can set it to transcode to MP3, WAV, or disabled. You can specify the sample rate and number of channels for the transcoding, but by default it will match the output speaker's setting. If you disable HA transcoding, then the media player only supports FLAC, MP3, and WAV files.*

I want bluetooth proxy, so I added this code:


esp32_ble_tracker:
  scan_parameters:
    interval: 1100ms
    window: 1100ms
    active: true

bluetooth_proxy:
  active: true

End result: bt proxy is working, microphones are working, but no audio playback.
Any ideas?

formatBCE · June 16, 2025, 2:17pm

I would strongly advise not doing it.
Bluetooth functionality is heavy lifting on itself (it’s using a lot of processor and radio time).
When you combine it with voice assistant - which is super heavy, as it needs a lot of RAM, CPU power (for wake word), streams big chunks of data (especially when playing audio or transferring command) - you have very unstable device, and i can’t even predict all the problems that can happen.

Just built with ESPHome 2025.6.0. Confirmed working.

Skyman1 · June 18, 2025, 9:33pm

when you say: “just built with ESPHome 2025.6.0” what exactly is built in the code? (just curious)

formatBCE · June 18, 2025, 9:46pm

I built current Respeaker firmware with ESPHome builder 2025.6.0. It’s just to make sure there was no breaking changes introduced in new major release (cuz it was the case several times).

formatBCE · June 30, 2025, 5:20pm

Next release of Home Assistant will bring streaming TTS to Wyoming, Voice PE, and, of course, to our Respeaker Lite!

tieppm1 · July 3, 2025, 8:37am

thanks for your great sharing.
I have seen your git

but I have some problems below

I can’t connect the mic to my home wifi, I don’t see the mic broadcasting wifi. I tried to configure wifi using the web https://web.esphome.io/ but it didn’t work.
I have to add the following code, right?
wifi:
ssid: “xxx”
password: “yyy”
The led on the mic lite board is always on, that’s probably not right, I don’t know if it’s an error during the build process or if my board has a hardware error.
thank you very much!

formatBCE · July 3, 2025, 12:38pm

Hey!
Yes, you need to use example config, it shows what to add Respeaker-Lite-ESPHome-integration/config/respeaker-satellite-dashboard-example.yaml at 20a1a58a20d3692d4f0ca5046c6da7878e104696 · formatBCE/Respeaker-Lite-ESPHome-integration · GitHub

The LED is on, because you didn’t solder USR button, as per instructions. Check README closely. It’s required.

luong · July 4, 2025, 8:36am

Can you please support the code with chat mode (wake up once and ask multiple times)?

tieppm1 · July 4, 2025, 2:28pm

thank you so much i followed the instructions and it worked. awesome

formatBCE · July 4, 2025, 2:40pm

Hey @luong!
The code has same abilities that Voice PE does. So if you have continuous conversation working with your LLM, it will work with Koala/Respeaker.
New functionality of asking questions works as well.

Skyman1 · July 5, 2025, 8:48pm

which led you are talking about?
I have 2 leds always on… one is green and one is red… is that normal?

Unfortunately I am not at home to show the pin soldered… but should be corrrect User - D2 and Mute - D3.

formatBCE · July 5, 2025, 9:45pm

Green one, on the side, is for power. It’s always on.
The red one in the center is on, when mic is muted.
Close to it there’s RGB LED, used for various indications by satellite software. That one should be off, until something’s happening - and I was talking about that one.
