Home Automation System

I'm using Home Assistant running in a Proxmox Virtual Machine. Whenever possible, I use WiFi to communicate with remote devices.

Integrations include:

The following hardware has been flashed with Tasmota & connected to Home Assistant using MQTT:

Sensors

Network Infrastructure:

Sample Tasmota device

GPIO1    Switch1   Fire alarm contact closure input
GPIO2    Relay1    Contact closure output
GPIO7    AM2301    HVAC Supply Temperature/Humidity
GPIO43   Buzzer    Buzzer
GPIO44   AM2301    Free Air Temperature/Humidity

The XIAO-ESP32S3 devices use firmware: tasmota32s3.bin with the template configuration: 

{"NAME":"GED-ESP32S3","ARCH":"ESP32S3","GPIO":[32,1,1,1,1,1,1,1,1,1,0,0,0,0,0,0,0,0,0,0,0,544,0,0,0,0,0,0,0,0,0,0,1,1,0,0,0,0],"FLAG":0,"BASE":1}

Devices can be configured by browsing to their IP address & going to Tools/Console. 

Tasmota settings:
Setoption8 On (Output temperature in °F)
Teleperiod 60 (Report to MQTT server every 60 seconds)
SwitchMode1 2 (when the GPIO pin is pulled low during a contact closure it reports "ON")
Rule1    Relay state follows the contact closure state
ON Switch1#State DO Power1 %value% ENDON
Rule2    Sound the buzzer then a contact closure is detected 
ON Switch1#State=1 DO Buzzer 1,5,1 ENDON
Rule3    Control a spot cooler based upon two temperature sensors
ON Switch1#State=1 DO WebSend [192.168.10.170] Power1 0 BREAK
ON Tele-AM2301-07#Temperature>80 do WebSend [192.168.10.170] Power1 1 BREAK 
ON Tele-AM2301-44#Temperature<80 do WebSend [192.168.10.170] Power1 0 ENDON
