Does it exist multisensor/relay by POE?

I need a device to install in each room of my house with the following features.
Does it exist has an already made product? is there any similar project?

Connection wired by POE not WIFI
sensor Temperature/humidity
sensor Light
sensor PIR
sensor 2CH magnet door
6CH relay (solid state)
3CH manual switch input

Lol, love the diagram!

In case it didn’t make sense to the op… you can buy poe hats for arduino boards (like uno), and of course those boards can do stuff like read sensors and toggle relays. You can’t just buy a device like that OTC pnp, afaik anyways. It will take some arduini programming at the very least.

If you are looking to flesh this out, there will be some fundamental limitation… poe max power will limit how many relay coils can be powered from the device itself. No problem if you can use interlocks to limit the number of energized coils at one time, but if you need all 16 relays on at once, you may need more than a poe hat can provide.

Even better an esp32 with ethernet and POE, then you can use esphome :slight_smile:

Solid state relays take about 30mA each and POE starts at 350mA 802.3af and can go up to 960mA, so for de deisred 6CH relays it should be OK.
If POE did not has the power I do not have problem on seperate power wires, but I want a wire LAN solution and not WIFI.

BRUH Multisensor | devices.esphome.io is near what I want, but I need LAN or POE connection, plus relays, and light switch input

Maby this?

nickrout’s suggestion still applies… no reason you couldn’t add an ethernet breakout to the esp32, as well as control a relay breakout or read switches (via GPIO binary_sensors). ESPhome can do all of the above.

[edit: Toni hit the reply button before I finished… that looks like an even better way to go. Just have to figure out the esphome config is all… and of course wire up your sensors, relays, etc.]

There at least two esp32 boards with inbuilt POE. The Olimex and another one which I cannot remember the name, but both are dealt with at length in another thread on here.

From memory both use the LAN8720 chipset so are compatible with esphome https://esphome.io/components/ethernet.html

I’m surprised that there aren’t fully developed projects with wired LAN devices.

I will have to add separated sensors + relays + code.

For me is a huge task, because I’m very rusty in code… many sleepless nights to come

esphome makes the code easy, or perhaps easier :slight_smile:

I think many people do not have poe through the house and wireless is just easier.

Olimex and wesp… each one around 30USD + sensors + relays
1 per room in house

I will try to make a prototype…

Thanks. Esphome seems to be the way to go and this 2 boards (olimex and wesp) seems to be the only ready made options

In response to the post you just deleted, Euro 17.95 for this one, just don’t plug in the usb while it is powered from POE. https://www.olimex.com/Products/IoT/ESP32/ESP32-POE/open-source-hardware

Here is the other thread by the way, ESPHome Ethernet connectivity feature request

I finnaly found that price, that’s why I deleted :slight_smile:Thanks

Be interested to know how you go. What are you controlling with the relays?

6CH relays for:

  • 2CH Window external blinds (open/close)
  • 2CH Light switch
  • 1CH radiant floor valve
  • 1CH future use

I noted a newish featherwing product recently https://hackaday.io/project/168356-poe-featherwing

This is getting close ESP32-EVB - Open Source Hardware Board
Missing yaml files to fully support it in HA

The full schematics are there to help with that.
