This release uses STM8 eForth to turn a $1.50 off-the-shelf W1209 into a data logging thermostat.
Features are:
- heating thermostat, e.g. for building chicken egg incubators
- basic sensor failure detection
- parameters for set-point, hysteresis, and trip-delay
- easy to use parameters menu (no need to search for a manual!)
- temperature logger with 0.1h to 10h interval, and a 288 entry ring-buffer
- logger access through a serial console
- fully programmable in Forth, even while it's running!
Although it's feature-complete, this is work in progress:
- Beta-grade "bleeding edge"
- not even an "endurance run" yet
Planned features:
- Improved logger with min/max temperature, and heating duty cycle
- Field-bus feature for thermostats
- more fail-safe features (parameter integrity, maybe a buzzer)
