Pairing the Xiaomi/Aqara Vibration Sensor (zigbee)

Goal: To pair the sensor to the CC2531 zigbee router.

See also CC2531 Router Operations

Enable Permit (aka pairing) Mode

I am using ZHA included in Home Assistant.

In Home Assistant (HA, aka hass), enable pairing mode:

Developer Tools > Services

The service to call is “zha.permit”

“ieee_address” is the zigbee MAC address of the zigbee router (eg. CC2531 running router firmware) that is permitted to add end-devices (eg. sensors) during the “duration” period.

If “ieee_address” is not provided, then the coordinator and all routers are permitted to add end-devices during the permit period. For Xiaomi sensors, I found it’s best to “lock” the sensor to the desired router (ie. closest router), so I always use “ieee_address” to ensure the sensor pairs to the router I want.

How to find the router’s MAC address

In HA with ZHA:

Configuration > Zigbee Home Automation > LUMI router > IEEE

Or, I run zha_map and read the “neighbours” file:

donn@fox:/usr/share/hassio/homeassistant$ cat neighbours/neighbours_00124b0019010203.txt
...
    "device_type": "Router",
    "ieee": "00:12:4b:00:19:01:02:03",
    "lqi": 104,
    "manufacturer": "LUMI",
    "model": "lumi.router",

Push the button on the sensor (a lot)

Here’s what happened after I enabled permit-mode:

Saw in home-assistant.log:

2020-06-25 15:34:49 INFO (MainThread) [homeassistant.components.zha.api] Permitting joins for 60s on 00:12:4b:00:19:01:02:03 device

Press and hold sensor button for 5s. Saw blue led flash 3 times.

Press button every 1 to 2s. See blue led flash once, on most button presses.

10s go by. Nothing is happening in the HA log, so…

Press and hold button for 5s, again.

Press button every 1 to 2s, again.

This time I start seeing messages in HA log that sensor is discovered.

IMPORTANT: Keep pressing the button every 1 to 2s for another 1 minute until new zigbee log messages no longer appear.

Next time, I will increase the “duration” from 60s to 120s to allow for more trial-and-error.

Verify the pairing

HA “Services” page: Call the service “zha_map.scan_now” to rebuild the zigbee network map data.

The router’s “neighbours” file confirms the Xiaomi sensor is a “Child” of the router, so pairing was successful:

CC2531 Router Operations (zigbee)

If you are having trouble with the CC2531 as a zigbee router (aka repeater), follow these steps.

The CC2531 router works well with Xiaomi sensors, which are notoriously picky about what zigbee routers/repeaters/hubs they work with.

When using the CC2531 as a router, you do NOT need to connect it to a Raspberry Pi (or other computer). You can simply plug the CC2531 into a USB-A charger like a smartphone charger.

This assumes you are running the CC2531 router firmware (router-cc2531-std.hex) that is part of the zigbee2mqtt project.

You do not have to run zigbee2mqtt. The CC2531 with router firmware is a totally standalone zigbee router.

This assumes you have already paired the CC2531 router with your zigbee coordinator (aka hub, aka gateway).

After pairing, ensure Home Assistant (HA, aka hass) has entity IDs for the CC2531 router. Search for “lumi_router”:

Ensure the CC2531 is in “normal operation” mode. If you see the LED flash/blink RED once every 4 seconds, then it is in normal operation mode.

Ensure the CC2531 has an active link to the zigbee coordinator. The S1 button on the CC2531 is valuable for testing this. I call S1 the “test button”.

When you press S1, the CC2531 LED toggles between flashing-red and green, and emits that state (green = on) like a sensor. That’s all it does. It’s only for testing. Green doesn’t mean the router is doing anything different. It’s just a “sensor” for you to test the link between the CC2531 router and your coordinator.

In HA, check Developer Tools > States and the state of the entity-id for your CC2531 similar to:

light.lumi_lumi_router_abcdef_on_off

The state of this entity will be “on” when the CC2531 LED is GREEN, and state will be “off” when the CC2531 LED is slow-flashing RED (every 4s).

NOTE: It may take 1 or 2 minutes for the state change to appear in the HA “States” page, so be patient.

If the entity state is “unavailable” or the state doesn’t change after 2 minutes of pressing the S1 button, then the CC2531 doesn’t have an active link with the coordinator.

  • If the CC2531 is far away, try moving it closer to the coordinator (or a known-good router) and testing again.
  • Try re-pairing the CC2531 with your coordinator.

You can also control the green/red LED on the CC2531 with HA service calls (light.turn_on), which also tests the connectivity between the router and the coordinator:

Also check the last time HA was in-contact with the CC2531:

Configuration > Zigbee Home Automation > lumi.router

Wyze Sense bridge & sensors with Home Assistant (hass)

You do not have to connect the Wyze Sense “bridge” to a Wyze cam. You do not have to use the Wyze app. However, if you need to update the firmware of the bridge, you’ll need to connect it to a Wyze cam and use their app.

Home Assistant (HA) version: 0.110.7

Connect wyze sense bridge to HA server using a USB extension cable to keep bridge away from server hardware (better RF rx/tx).

lsusb:

Bus 001 Device 018: ID 1a86:e024 QinHeng Electronics

Device path for wyze bridge:

donn@fox:~$ ls -l /dev/hidraw0

crw------- 1 root root 238, 0 Jun 19 20:41 /dev/hidraw0

Map this into HA container with portainer like we did with Conbee II, except device path will be the same inside the container: /dev/hidraw0

Update: No need to add the github url as a Custom Repository in HACS.

Update to latest version of HACS. Restart HA.

Go to HACS tab in HA. Search integrations for “wyze” and install “Ha Wyzesense” integration. Restart HA.

bash-5.0# lsusb | grep -i 1a86
Bus 001 Device 018: ID 1a86:e024 QinHeng Electronics

Add to configuration.yaml:

binary_sensor:
  - platform: wyzesense
    device: auto

And restart HA again.

Log:

bash-5.0# cat home-assistant.log | grep -i wyze
2020-06-19 21:03:58 WARNING (MainThread) [homeassistant.loader] You are using a custom integration for wyzesense which has not been tested by Home Assistant. This component might cause stability problems, be sure to disable it if you experience issues with Home Assistant.

Wyze Sense bridge LED is steady blue (good).

Developer Tools > Services.  In the Service box, type “wyze” and see wyzesense.scan service.

Per docs, call the service and, within 30s, push the sensor’s reset button until LED flashes 3 times.

Bridge LED changed to flashing blue but pairing failed “with no sensor found”:

Enabled debug for the custom component. No interesting log messages.

2020-06-19 21:28:09 DEBUG (SyncWorker_4) [custom_components.wyzesense.binary_sensor] Scan completed with no sensor found.

Saw tip from BlindLemon comment on github issue, and found the following pairing procedure worked OK:

Press bridge’s button until its led goes solid yellow. Call wyzesense.scan using Developer Tools > Services (flashing led on bridge). Now hold-down reset button on door sensor for 3s. It pairs and bridge led goes solid blue.

Now there’s a new entity in Developer Tools > States:

It is nice to have rssi and battery level information for setting up alerts/notifications.

Note: When pairing my 2nd sensor, I did not have to press the bridge’s button. Just call wyzesense.scan and hold down the reset button on the sensor for ~5s, release, and it was paired and appeared in HA States page.

Door sensor states in HA:

off = The two pieces are touching (or close enough, about 1 inch)

on = The two pieces are far apart

Create a sensor for the battery level

Here’s the native sensor:

Make a custom sensor using the battery_level attribute (configuration.yaml):

sensor:
  - platform: template
    # Custom sensors created from other ents' attributes.
    sensors:
      wyzesense_70123456_battery_level:
        friendly_name: "Door sensor 70123456 battery level"
        unit_of_measurement: '%'
        entity_id: binary_sensor.wyzesense_70123456
        value_template: "{{ state_attr('binary_sensor.wyzesense_70123456', 'battery_level') }}"
        device_class: battery

Restart HA and check States page again for the newly created sensor:

Add wyze battery level to grafana:

Zigbee: Conbee II installation, Home Assistant, ZHA, SmartThings button

Goal is to get SmartThings zigbee button working with Home Assistant first. Then, Wyze Sense sensors. Conbee II will be the zigbee coordinator (aka gateway, aka hub).

Use Windows PC to update firmware and set 2.4GHz channel. Download GCFFlasher and deConz.

GCFFlasher.exe install error:

The code execution cannot proceed because FTD2XX.dll was not found. Reinstalling the program may fix this problem.

So skip for now and install deConz for Win. Connect Conbee II. deConz app says frequency band is 2400 – 2483.5MHz.

Ensure status is “Not in Network”, else click “Leave”. Click icon for “Network Preferences”, top-center. Device type = Coordinator with Channel Mask 15.

Metageek diagram:

Don’t untick current channel, but rather tick channel 20 checkbox then “Save”, “Done”. Close deConz. Restart deConz. Verify channel is 20.

Download firmware deCONZ_ConbeeII_0x26580700.bin.GCF

Download D2XX drivers 2.12.28 (x64). Copy ftd2xx.dll from “i386” folder of drivers to same folder as GCFFlasher.exe.

Open powershell shell, navigate to folder with  GCFFlasher.

Grafana

Grafana query, because SmartThings button has a temperature sensor inside:

According to grafana/influxdb, the SmartThings button is reporting its battery level (%) every 3 hours. But next day, changed to every 10 hours.

Reuse a Node Red flow for multiple devices

The key for me was the ability to extract strings from mqtt topics (msg.topic) with regex’s.

Eg. using node red’s Change node and jsonata expressions:

$match(topic, /binary_sensor.(cam_\w{5})_motion/).groups[0].$string()

That gives you ‘bacon’ in binary_sensor.cam_bacon_motion. Set msg.data.foo to that and the flow can be used for anything matching the regex. Moreover, you can use $.data.foo in the same change node to set other msg.*

It’s really powerful.
