Today I’ve finally gathered myself and installed the long awaited kitchen worktop sockets. #Zigbee of course, #BSeed ones, I guess #Tuya compatible, but I obviously run them via #HomeAssistant without any issues.

It was a bit complicated, because it’s 2 triples with a bit tight cables, but in the end it was a success. I can now reuse #Insplening outlets somewhere else, where they won’t stand out that much.

**Flood detection in Home Assistant**

(link to blog)

TL;DR

Initial test of cheap Tuya water leak sensors (zigbee) – all connected successfully, all detected water under a second.

Their longevity, battery duration and stability in zigbee mesh remains to be seen.

Why

Dishwasher’s aquastop valve died and we had a small flood in the kitchen. Then I ordered not one, but five water leak detection sensors. For other critical rooms, of course.

Sensors

The two types of sensors I ordered (Tuya brand) were recognised in Home Assistant / Z2M as:

  • Red ones: OUI: Telink Semiconductor (Taipei) Co. Ltd., Zigbee Model TS0207 _TZ3000_bfopm9ga
  • White ones: OUI: Telink Semiconductor (Taipei) Co. Ltd., Zigbee Model ZG-222Z HOBEIAN

Both are powered by CR2032 battery. The batteries were included, but one was dead and I had to replace it. Red ones had plastic strip around the battery to prevent emptying. Batteries did not have it, and batteries had an initial state of charge between 5% – 80%.

Other differences?

  • Red ones have sound alarm built-in (although very quiet), white ones don’t have it
  • white ones have sensor also on top, red ones don’t have it

Pairing in Z2M

There were no issues with pairing to the zigbee network. I held the upper button for 5 seconds, enabled ‘Permit join’ in Home Assistant / Zigbee2MQTT add-on and devices were recognised and added to the mesh in a few seconds. I only rename them using my system: Brand function number (room), e. g. Tuya water 01 (kitchen).

After pairing, the following entities were exposed (for both types of sensors):

  • Sensors:
    • moisture
    • tamper (not sure what it means – does it turn on if i dissasemble it? open the battery cover?)
  • Diagnostics:
    • battery state
    • battery %
    • last seen (disabled by default), I enabled it
    • link quality (disabled by default)

After pairing, I had to press the top button once, to enable communication with z2m mesh. Before that, only last seen and link quality entities were shown, others not.

Physical placement

I’ve put sensors:

  • under the dishwasher / kitchen sink
  • under the washing machine
  • under the aquarium cabinet
  • under the roof window – attic (it already leaked twice)
  • boiler room – in the middle of the water boiler and hot water buffer, right under all central heating valves and pumps

    • Organization in HA

    I’ve created a separate dashboard to show all water leakage sensors (using plain ‘entities’ card for each room):

    At the moment I don’t have a better idea how to organise them. I’ve also added them to ‘areas’ which represent rooms.

    When I was at it, I also classified ‘areas’ in appropriate ‘floors’.

    Automations – notifications

    I’ve set up automations that send a notification to family phones, tablet and TV if the flood is detected.

    TODO

    Replace the main water valve with motorized one and create automation that shuts it off in case of water leakage.

    86-type Smart Home control panel features a 3.5-inch display, physical buttons, Bluetooth SIG Mesh gateway

    The Tuya WiFi 3.5-inch Smart Center Control Panel (CCP-S05) is designed to replace traditional 86-type switches while adding a Bluetooth SIG Mesh gateway, a touchscreen interface, and three buttons for smart homes, apartments, and small commercial spaces. Compared to other 86-type control panels such as the Luckfox-Pico-86-Panel, Dusun DSGW-130, and Waveshare’s ESP32-P4 Smart 86 Box, the Tuya device follows a hybrid approach, combining a capacitive touchscreen with three physical buttons for instant local control. Tuya WiFi 3.5-inch Smart Center Control Panel (CCP-S05) specifications: SoC – Unknown (potentially based on Allwinner F1C100s ARM9 application processor, slightly more powerful Rockchip or Allwinner SoC) Display – 3.5-inch capacitive touchscreen Audio – Built-in microphone and speaker Networking Wi-Fi (2.4 GHz) Bluetooth Mesh USB – USB Type-C port for debugging only Relays – 3x independent relay channels (200 W per channel max 600W) Misc 3x programmable physical buttons Reset button (on the bottom side) RTC

    Ich habe gestern einfach mal auf Gut Glück HomeAssistant installiert um zu sehen, wie weit ich da komme ohne meine bestehende Smart Life Umgebung auseinander zu rupfen.
    Positiv: Ich konnte die bestehenden Geräte per Tuya-Integration direkt einbetten.
    Negativ: Es klappt kaum etwas wie es soll.
