    Do I connect the xiaomi aqua door sensor to the esp wrom with easy or other software? Or are there any other sensors on wifi that can be paired with the esp wrom.

    .
    No, because Xiaomi's ZigBee module is different from Wifi and requires a special gateway.

    This is what I don't understand anymore, please specify what "pair" means to you.
    You can connect most sensors to GPIO ports and the list is long:

    Since they are wireless they already work after some "radio"?

    Or were you more concerned with "how to connect regular detectors and reed switches wirelessly over wifi" ?
    Write more about what you want to achieve, then it will be easier to advise something.

    Exactly as you write "how to connect ordinary detectors and reed switches wirelessly over wifi"? And program it via esp wroom

    So you can esp program with Tasmota, ESP Easy or Espurna. These are very similar solutions to each other.
    Connect the sensors of your choice to the esp pins and send their status to some IoT system.... Homeassistant, Domoticz or an MQTT broker. These also have their own web pages through which you can control or read the states and create internal simple automations.
    What you want is totally doable.

    I don't want to connect the sensors to the esp via cable, but I want to control the status of the reed switches, high or low, and the PIR detectors all via wifi.

    Devices with Wifi as the transmission medium, are power intensive and powering them from batteries is problematic. I don't think you can buy off-the-shelf solutions and build anything sensible. You are left with one with a 'normal' 433MHz radio. It is possible with a bit of persistence to combine this with esp, Read about the Sonoff RF Bridge 433MHz RF and its mods, but I see it poorly due to the use of different coding protocols by sensor manufacturers.
    There is RFLink which operates over the radio. You still haven't written what you want to do with the received data....

    If you don't care so much about doing it yourself, buy ready-made Sonoff 433Mhz sensors and the aforementioned gateway.
    Integrate this using a dedicated app.
    Clean, fast, cheap and wireless.

    If you continue in the DIY direction, the ESP alone will not be the end of it, there will be the problem of sending emails.

    I still have an arduino mega. Actually it is better to do it wired. Only I have yet to figure out how to connect 10 sensors to the esp

    The sensors are nothing more than a button - they have a contact on their output.
    So the same as a button;
    https://microcontrollerslab.com/push-button-esp32-gpio-digital-input/
    You have the module, so upload the tasmota and start for now with the usual buttons "on the table". in small steps, first add one, then another.

    Read up on the rules to see if you can continue. Unfortunately, if you don't want a master system, you will have to go through this.
    https://tasmota.github.io/docs/Rules/
    https://tasmota.github.io/docs/Scripting-Language/

    It costs you nothing, apart from a bit of effort.

    This one would also be suitable, it would just be enough to rename the names on the terminal blocks.
    There is nothing else there but a pin-screw connection;
    I have not seen anything else like it

    Can you advise me on the best solution, as I am thinking of either building a display under the RPI to control e.g. domoticz and communicating with esp via wifi, or building on an arduino and plugging it under the RPI. Unless you have other ideas

    There is no best solution, it all depends on your skills and preferences
    Stay with esp wifi gives more flexibility.
    Domotycz seems easy at first, as most can be cobbled together and the implementation process is quick. However, as your needs grow, the limitations come out. As a first - is a good choice.

    The second (of many) is Home Assistant. It is a little more difficult, as it requires configuration via .yaml files and more learning. After that, it is fairly even.
    The advantage is a better mobile app and you can use a tablet instead of a display.

    If you don't want to decide now, put an MQTT broker on the RPI, which is also supported in Tasmote and EasyEsp (just like domoticz and HA).
    Then the transition of Domoticz<>HA will be painless (both support Mqtt).

FAQ

TL;DR: 433MHz RF is battery-friendly; Devices with Wifi as the transmission medium are power intensive. For ESP32 alarms, wire PIR/reed sensors to GPIO or use an RF bridge, then publish events to your hub. [Elektroda, starob, post #19756158]

Why it matters: It helps DIYers choose a reliable way to link door/motion sensors to ESP32 Wroom without dead batteries or protocol mismatches.

Quick Facts

Can I connect a Xiaomi Aqara door sensor directly to an ESP32 Wroom?

No. Aqara uses Zigbee, while ESP32 speaks Wi‑Fi/BLE. You need a Zigbee gateway or hub to bridge it. [Elektroda, starob, post #19755907]

What does pairing sensors with ESP32 over Wi‑Fi actually mean here?

In this context, you wire sensors to ESP32 GPIO pins like buttons, then the ESP32 reports their state over Wi‑Fi to your home platform. [Elektroda, starob, post #19756054]

Are Wi‑Fi PIR and reed sensors practical on batteries?

Usually no. Devices with Wifi as the transmission medium are power intensive. Prefer mains power or 433MHz RF sensors with a bridge if you need wireless. [Elektroda, starob, post #19756158]

Whats the simplest ready-made wireless route if I dont want DIY?

Use Sonoff 433MHz sensors plus the Sonoff RF Bridge. Integrate them in the vendor app, then into your system if supported. [Elektroda, starob, post #19756912]

How do I wire a reed switch or PIR to ESP32 and publish events?

Use Tasmota and treat each sensor like a button. 1) Wire sensor between a safe GPIO and GND, enable internal pull-up. 2) Flash Tasmota, assign the GPIO as Switch in Module settings. 3) Set MQTT, then use Rules to publish or trigger alerts. [Elektroda, starob, post #19757015]

How many sensors can an ESP32 handle for this project?

An ESP32 has multiple usable GPIO pins, so several inputs are feasible. Start with one sensor, validate logic, then add more step by step. Use Rules for behavior. [Elektroda, starob, post #19757015]

I have 10 sensors to monitor. What topology makes sense?

For 3 PIR and 7 reed switches, group nearby sensors to an ESP32 node. Publish states over MQTT to your hub for alarms and dashboards. [Elektroda, Michal8883, post #19756524]

How do I trigger a siren and send email or push notifications?

Drive the siren via your hubs automation. Let Domoticz or Home Assistant send email/push, since email from ESP alone is cumbersome. [Elektroda, starob, post #19756912]

Domoticz vs Home Assistant  which should I choose?

Domoticz is quick to start but shows limits as needs grow. Home Assistant takes more setup, but offers stronger apps and flexibility. [Elektroda, starob, post #19759541]

Can I control everything from a Raspberry Pi display or a tablet?

Yes. Run Domoticz or Home Assistant on the Raspberry Pi. Use their web UI or a tablet app as your wall display. [Elektroda, starob, post #19759541]

Is 433MHz with an RF bridge a good idea for wireless sensors?

It works, but note a risk: different manufacturers use different RF protocols, limiting compatibility and decoding. [Elektroda, starob, post #19756158]

Do I need a screw-terminal breakout for ESP32 Wroom boards?

A generic screw-terminal breakout is fine; its just pin-to-terminal wiring. Relabel terminals to match your Wroom pinout. [Elektroda, starob, post #19757101]

Whats the best way to start without getting overwhelmed?

Flash Tasmota, connect a single button sensor on the bench, and test Rules. Then add sensors incrementally. [Elektroda, starob, post #19757015]

How do I integrate ESP32 sensors with MQTT, Domoticz, or Home Assistant?

Configure ESP32 firmware (Tasmota/ESP Easy) to publish sensor states via MQTT. Your hub subscribes and runs automations or alerts. [Elektroda, starob, post #19756054]

Can I switch later from Domoticz to Home Assistant without redoing everything?

Yes. Put an MQTT broker on the Raspberry Pi now. Both platforms support MQTT, so migration is straightforward. [Elektroda, starob, post #19759541]
