nspanel-sauna

References and sources

This project is based on several sources working with the Sonoff NSPanel:

• https://github.com/blakadder/nspanel
• https://github.com/peepshow-21/ns-flash
• https://github.com/joBr99/nspanel-lovelace-ui

Goal

Replace an traditional sauna control panel with the Sonoff NSPanel.

• read two temperature sensors for safety reasons
• manage set-point temperature on display
• overheating protection
• maximum heating time
• timer based preheating

Additional ideas

• flash the light inside the sauna to indicate a preset session finished

Hardware modifications

• use relay 3 pin to connect DS18B20 temperature sensors
• relay 1 controls a four terminal contactor to switch the sauna oven
