What board for reading a reed switch pulses (even better two) + Zigbee connection?

Hello,

I need to read the pulses from a reed switch (connected to a water meter) and make them available to a software (an homeautomation one, like Home Assistant) via a network protocol such a Zigbee but I don't know what board should I get (I'm new in ESPHome).

As I have two water meters, if I could use a single board to read both meters (with distinct values) instead of using 2 boards it would be better.

My need:

  • Read reed switch pulses
  • Single board to read 2 meters
  • Zigbee connectivity

My questions:

  • Board model/size adapted for the use.
  • Push or pull method: Should the board push values to Zigbee controller or should the board keep last value for Zigbee controller to read it.

I think I can code the logic but if one already exists I'll use it.

Thank you

Looking for: wired camera doorbell without IP at the door (aka front door module is remote)

Hello,

I'm looking for a:

  • connected camera doorbell
  • local-first/only networking
  • without any subscription
  • compatible with Frigate and Home Assistant

I'm against Wi-Fi for this usage as wires are more reliable, but I'm reluctant to have an Ethernet cable run all the way out to the street (public zone): someone could destroy/unscrew the camera and connect on the network.

(I know VLAN can provide a way to isolate the camera and thus theoretically prevent this attacker to gain access to the network: It's a tech-solution I'm trying to avoid if possible)

So I'm looking for a 2-parts doorbell:

  • the button+camera module for the street
  • and the "intelligent/network" module (for configuration) to install in the house

Both would be connected together using simple non-LAN cable, preventing someone breaking the "street module" to gain LAN access.

For example, Hikvision has 2-wire (and also 4-wire) video intercom for retrofitting, reusing building's existing wires, with 2 modules.

Do you have some product to recommend?
