so i seen the videos of blue tooth thermostat connects to esp32 device that then talks to home assistant
i dont have a bluetooth device… but i have am2302 and also want to add a PIR sensor
i have 2 esp32 wroom32 devices
i cant seem to figure it out…
so
1 esp32 wroom will have am2303 and a pir sensor and 200 feet away will be the other esp32 wroom32 being the sever bluetooth that the sensor will talk to and then i can read it in home assistant through the wifi
so how do you connect it… there isnt much google videos and the esphome is vag on ble tractor and server so i lost what to do
so it be like
esp wroom (with pir/am2302) client sensor --------> esp wroom (server) ------> home assistant
using the bluetooth ble client server what not stuff
Yeah good luck with that maximum range specification. You are not going to get more than 5-10m from an ESP32. I’ve tried a few boards, they are all the same.
Also there is no ESPHome BLE server component that I am aware of that links to other ESP modules. All the components have been written to link to specific devices and while there is a generic client device there is no generic server.
ah ok
and i figured since these 4 dollar xami thermometers can connect to esp32 bluetooth then the esp32 wifis to home assistant… then i should be able to use a esp32 instead of a xami thermometer
and ok i figured that be great can go go a few hundred feet… go figure eh 30 feet
Instead of bluetooth (which not covers the distance you want to achieve and were no component is available for esphome anyways) you might wanna give esp-now I try. This allows you the p2p communication you want to achieve and should have no problems with the you wanna cover.
By now their is no stable/official esphome integration but only a pr you can try:
well if there is no esphome ble server component then why does esphome website state there is one?/ BLE Server — ESPHome
well i from what i understand xiaomi devices transmits the data to the esp32 device and then it re transmit it to home assistant… why cant it transmit the same data like from a dht22 to the esp32 ble server and then to home assistant… all your transmitting is the number arent ya? no idea
aso for the espnow… i did try that i having issues with that… thats esp to esp and i read it can cover 700meters doing blu tooth with the wroom32 but i didnt find at the momment a espnow to home assistant plugin
so 2 esp32 wouldt connect with espnow and then transmitt to home assitant… plus with the esp32 ble server then youd have like 6 bluetooth devices connected to the esp32room and then it transmitts to home assistant…
least thats what the guy does in his video
and ill check out those 2 links
i appreciate the help so far. nothing is perfect lol always learning (
That is not the same Bluetooth.
You need some high powered Bluetooth chips for that range. They are common in MC intercoms but mobile devices and smaller electronics usually have a range limit of 10 m at best.
And one more hint: don’t trust any marketing bullshit like “up to xxx meters”. Those are typical totally unrealistic numbers you never are able to achieve in real life scenarios.
oh ok … ya i new to this stuff so there is some good info some info that confuses me greatly and some stuff i kinda understand etc…
figuress the bs ranges… i live out in the country and i know i have a steel shop so i bet that even would bugger up BLE or bluetooth
i have no idea anymore lol all that blue stuff lol
