Wait, you have a delay of seconds on your doorbell notification? Wow, over here that would probably mean the UPS guy at the door has already run off the driveway and you can now go and pick-up your packet elsewhere ... (Joking of course - but not by much)

I was using espnow before. I was using it mostly for the reason it is really fast to send and receive a packet (i've measured under a millisecond) and also because this system works without using a wifi so in some cases making the hub reliable may be desirable. I have not yet made a hub myself, i was using it to control lights to the rythm of music with a ps2 controller. So i don't know if esp now hubs will fail sometimes, but it seems to me its possible to make a very reliable system.

This is a great project! Your title makes it sound like you have given up on ESP-NOW. It seems you are making the best of both worlds, ESP-NOW and WiFi.

I like the idea, but isn't a shelly door sensor the same with already a optimized fast response time?

Running espnow on esp32 with continuous data transfer heating esp board. Are there any specific requirements to throttle up data sending rate for optimum heating??

Hi thanks for this project. I'm trying to start one by one and ..to start first with attiny...i uploaded your code tested . but in deep sleep its consuming 300uA . not sure why is that? is that's how your code supported to work for attiny in deep sleep? i just power attiny and used a switch input that's all..all.othe pins are floating or untouched

Very educative video Can you make on iot 32/64 channel home automation with esp32 or esp8266

If you use ESP32 on your hub I think you will need only one module for both receiving ESP NOW messages and connect to AP and send data to MQTT broker. Why are you instead using 2 ESP8266?

set a static ip in the code, and the esp will connect much faster most of the time

could you not use esphome to code it

I was seriously surprised by the cost of your contact sensor. It's like 4 times as high as I expected it to be. What drives the cost so high? This just seems like a dev board with a microswitch, which is like a $1-2 component. Very discouraging, since my product would be basically the same thing with about 5 microswitches and would also require a 3d printed part.

Well I have designed my own made a Wemos d1 mini deep sleep wake shield if you define mac address in wifi settings in your code you can connect and send message to home assistant MQTT broker as low as 500ms not fast as ESPNow ofcourse but you dont have to deal with a ESPNow to mqtt hub anymore😉 cause even I mod my Wemos d1 mini's for less consumption in deep sleep mode which is 17uA but The hub does not sleep and it is always open. Acorrding to datasheet of esp 8266 modules ex: wemos d1 mini ESP12F can consume around 75 to 80mA when in Wifi Station mode so long term battery powered hub is not possible solution. I highly recommend you to try connectting with defining AP MAC address configuration you will see it will connect to your AP about 500ms or 600ms depends on your Router configuration also make sure to configure wifi Channel on your Router and on sensors wifi configuration code
