[Home Assistant] Zigbee2MQTT – ‘MAC channel access failure’ (225)

Suddenly, some weeks ago, devices in my Zigbee network started to become sometimes unavailable and did not respond. This occurred at random times and on random devices. When checking the Zigbee2MQTT logs, it was flooded with MAC channel access failure error messages.

When searching for this error message, this GitHub issue pointed me to the potential issue: Network Interferences (probably Wi-Fi). See also the official docs here.

I have two ZigBee networks in parallel. One using ZHA and the Conbee II stick running on channel 20. And one using Zigbee2MQTT using a Sonoff ZBDongle-P (CC2652P) running on channel 11, which had the network issues. Without further investigation, I thought, let’s check what channel my own Wi-Fi is using and if it is on channel 11, simply change it to something else (which turned out to be a completely wrong approach). In my FritzBox router, the channel selection was configured as “auto”. So no specific channel set. That made sense to me, as the ZigBee issues randomly appeared, so perhaps only when the Wi-Fi switched to a channel, ZigBee was already using.

Without further investigation, I simply set the Wi-Fi channel to 1, so that it does not interact with Zigbee channel 11 (just to mention it here again: this is completely incorrect!). But things got worse, instead of better.

After reading this great blog post about building a stable Zigbee network and seeing the graph from Metageek about Wi-Fi and Zigbee channels, I noticed my issue…

Wi-Fi Channel 11 <> Zigbee Channel 11

By simply looking at the Metageethek graph, I understood why I made things even worse. My newly selected Wi-Fi channel 1 interfered directly with Zigbee2MQTT channel 11.
SmartHomeScene is recommending the following channel settings in their blog post:

  • Zigbee channel 11, Wi-Fi channel 6 or 11
  • Zigbee channel 15, Wi-Fi channel 11
  • Zigbee channel 20, Wi-Fi channel 1
  • Zigbee channel 25, Wi-Fi channel 1 or 6

So I tried switching my WI-FI to channel to 11, which should not interference with ZigBee channel 11. And yes, Zigbee2MQTT was now running fine, but suddenly the MAC channel access failure error messages appeared on ZHA. Seems like the ZHA ZigBee channel 20 was sill too close to WI-FI channel 11. So I thought, why not using a WI-FI channel, which is completely out of the ZigBee range. I switched my Wi-Fi from channel 11 to channel 13, and everything runs smooth since then. Finally, my ZigBee network is “rock solid”! 🙂

[Home Assistant] Update firmware on Sonoff Zigbee USB Dongle-P

First, confirm that you have a Sonoff Zigbee 3.0 USB Dongle Plus. Go to Settings → Hardware → All Hardware → Search for Zigbee

Check your current firmware version:

Important: Stop Zigbee2Mqtt before flashing, as described in the docs!

Now let’s add the ZigStar repository: Settings → Add-ons → Add-on Store → Three dots → Repositories → Add https://github.com/mercenaruss/zigstar_addons

After that, install the Add-on for Texas Instruments CC2652P7 based radios.

Copy the firmware link from here: https://www.zigbee2mqtt.io/guide/adapters/

Got to the Configuration of the installed ZigStar Add-on and paste the firmware link and select the two radio buttons like bellow.

If you receive an error when saving the configuration, simply add 127.0.0.1 as Network Device and save again.

If the Configuration is successfully saved, start the Add-on and flashing will start immediately.

Switch to the Log tab and hit refresh until you see the “successfully stopped” message.

Now you can stop the ZigStar Add-on and start Zigbee2Mqtt again and check your new installed version.

Done.

[Home Assistant] Mushroom Template card – Badge Icon

Somehow, I’ve only just realized that a badge icon can be used to display another entity status on a template card, even though it’s written in the documentation. I now use it to display the status of presence or motion sensors in the respective rooms.

badge_icon: >-
  {{ "mdi:motion-sensor" if states("binary_sensor.0xb4e3f9fffeb689d4_occupancy")  == "on" }}
badge_color: >- 
  {{ "green" if states("binary_sensor.0xb4e3f9fffeb689d4_occupancy") == "on" }}

[Home Assistant] Confirmation dialog

Just noticed that you can add a confirmation dialog on a tab action.

Very helpful to prevent things from being activated by mistake.

[Home Assistant] Display Reolink Recordings from a NAS using the Gallery Card

A few months ago, I installed a Reolink Doorbell at our front door. Since then, I’ve used it for simple automations like sending a photo when someone is at the door. To capture a photo, I was using the camera.snapshot service. I never used the photos and videos that the doorbell itself recorded and that were stored on my TrueNAS system via FTP. Mainly because I haven’t found a good way to display the captured photos and videos on my Dashboard. But finally I was able to fill the gap with the Gallery Card, which turned out to be exactly what I needed the whole time. By using it, you can simply display the latest images and videos, even when they are stored in some kind of nested folder structure, and it also helps to parse filenames to display them in a more convenient way.

Following a brief overview of what I had to do:

  • TrueNAS
    • Create Dateset, in my case it’s: data/camera
    • Share the dataset via NFS
      • Sharing → Unix Shares (NFS) → Add → Choose your new dataset
    • Create some folder(s) on your new dataset, for example: /Reolink/Wifi-Doorbell/Recordings (to do that, simply mount the NFS share to your local machine or use the terminal)
    • Activate the FTP Service
      • Services → FTP
  • Reolink
    • Go to Settings → Surveillance → FTP
      • Insert your TrueNAS FTP credentials
      • Remote Directory: /Reolink/Wifi-Doorbell/Recordings
      • Generate subfolder by: YYYY-MM-DD
      • Select what and when you want to record something
  • Home Assistant
    • Add your Doorbell via Reolink Integration
    • Mount NFS Share
      • Settings → System → Storage → Add Network Storage
      • Name: Reolink (whatever you like)
      • Usage: Media
      • Path: /mnt/data/camera
    • Check if you can access your recordings
      • Media → My media → media → Reolink (NFS name)→ Reolink (my folder name)→ Wifi-Doorbell → Recordings
    • If you cannot open your files, you probably have to adjust your permission on the TrueNAS Dataset. Provide at least read permissions (e.g. 655)
      • Storage → Pools → camera → Edit Permissions
    • Install Gallery Card
      • HACS → Frontend → Explore & Download Repositories → Search for Gallery Card
      • Go to your Dashboard and add the card
type: custom:gallery-card
entities:
  - media-source://media_source/media/Reolink/Reolink/Wifi-Doorbell/Recordings/
maximum_files: 25
menu_alignment: top
folder_format: YYYY/MM/DD
video_loop: true
video_autoplay: true
video_muted: true
file_name_date_begins: 12
file_name_format: YYYYMMDDHHmmss
caption_format: HH:mm:ss DD/MM

Most variables are self-explanatory and also well explained by the galery-card docs, but below a few words about the settings I used, beginning with the path to the media which is provided on the entities attribute.

entities:
  - media-source://media_source/media/Reolink/Reolink/Wifi-Doorbell/Recordings/

The first part is a default value: media-source://media_source/
Followed by the usage type and name we have chosen when mounting the NSF share: media/Reolink/
Then we need the directory path: Reolink/Wifi-Doorbell/Recordings

Because we chose in the Reolink settings “Generate subfolder by: YYYY-MM-DD“, the files are stored in a hierarchy like this:

  • 2023
    • 10
    • 11
    • 12
      • 01
      • 02
      • 03
      • 04
      • 05

The gallery-card can automatically parse this, if you provide the following setting: folder_format: YYYY/MM/DD.
And because the filenames look like this: Haustuer_00_20231230143626.jpg, you have to add file_name_date_begins: 12 to skip the firs letters, and file_name_format: YYYYMMDDHHmmss to parse the date. With caption_format: HH:mm:ss DD/MM you can define the output, how you want to display the parsed timestamp.

[Home Assistant] Person card

I recently saw this cool dashboard and the person cards caught my eye. As the dashboard creator also provided all the yaml code and a really helpful guide, I tried to rebuild it. I was already using the mushroom-person-card, so I “just” had to add the little icons (mushroom-chips-card) below it (using the vertical-stack-in-card). To display the network type and the charging status, you first have to enable these sensors in the Home Assistant Companion App on your mobile phone. This is my result:

[Home Assistant] Template sensor which combines door lock and contact sensor

Cool template sensor idea I found here, which combines the states of two sensors and display the different combined states. Useful if, for example, you want to combine a door lock and a contact sensor on the same door.

Settings -> Devices & services -> Helpers -> Create Helper -> Template

{% if is_state('lock.kellertur', 'locked') and is_state('binary_sensor.kellertur_contact', 'off') %}
  Locked
{% elif is_state('lock.kellertur', 'unlocked') and is_state('binary_sensor.kellertur_contact', 'on') %}
  Open
{% elif is_state('lock.kellertur', 'unlocked') and is_state('binary_sensor.kellertur_contact', 'off') %}
  Closed, Unlocked
{% elif is_state('lock.kellertur', 'locked') and is_state('binary_sensor.kellertur_contact', 'on') %}
  Open, Locked 
{% else %}
  Unknown
{% endif %}

Helpful to check whether a door is really closed when locking it via a smart lock. Because else it could happen, that you would see status “Locked“, although the door is still open. But with this helper, you will get in this situation “Open, Locked“.

To emphasize such a situation even more clearly, you can of course also add some icon colors.

[Home Assistant] Motion sensor in combination with Adaptive Lightning

I have some lights in my garden which are turned on in the night and are controlled by the Adaptive Lighting component, to automatically adjust brightness and color during the night. But if someone comes home late and this is detected by a motion sensor, I wanted to increase the brightness of all the lights in the garden for a short time.

Increasing the brightness was easy, as it can be done by using the light.turn_on service. However, it took me a few minutes to figure out how to reactivate adaptive lighting on these lights when motion is no longer detected. But it’s actually super simple (and it’s directly written on the GitHub start page here and here). You just have to deactivate the “manually controlled” flag that got activated by “manually” increasing the brightness. Following an example with a single motion sensor (binary_sensor.haustuer_motion), a lamp (light.haustur_light) and the adaptive lightning switch entity (switch.adaptive_lighting_haustuer).
