In this video I do humidistat replacement with a Tasmotized Sonoff SV using Home Assistant for command and control.
I video myself doing these things real time, so you see most of my mistakes as well as my successes. I feel that both are important as maybe I can prevent you from making the same mistakes. I suggest watching the whole thing to see what worked and what didn’t before you start.
Included is the wiring, mounting, assembly, and set-up of the Tasmota software and the Home Assistant software to make this work in my system to replace my broken Honeywell H6062A1000 HumidiPro humidifier control that failed after less than a year of use.
NOTE: Updated November, 2020……
If you want to skip ahead to programming, here are some time syncs:
03:24 –
Start of Tasmota configuration of the Sonoff SV using Tasmotizer on Ubuntu
16:35 –
Start of Home Assistant programming
NOTE: Updated February, 2023. New Blueprint added to greatly improve function and control: https://github.com/SirGoodenough/HA_Blueprints/blob/master/Automations/HumidifierWaterThrottleControl.md
