ESPHome VS. Tasmota : When to Use Which and Why

+

20210404· The ESP8266 is cheaper but doesn’t have as many functionalities, and has some limitations when it comes to GPIO mapping. The ESP32 is much more powerful, latest, futureproof, comes with more GPIOs with multiple functions, has a faster WiFi, supports BLE. ESPHome VS. Tasmota . Tasmota is a readytouse solution as an alternative for Sonoff ...

Knowing how the motor operated I decided to create my own controller using an esp8266 with two relays controlling the 12 volt supply to the motor. Although there are mains powered motors available, choosing the 12 volt DC motor allows the whole controller and motor assemble to run off a 12 volt power pack which was easier to run cables to and will keep the Australian authorities happier, as ...

CO2 sensors need to be calibrated now and then, the default for MHZ19B being Automatic Baseline Calibration (ABC) to lowest measured values every now and then (day?), which would be assigned the ballpark outside CO2 figure of 400 ppm. This is far from accurate and cannot be used to monitor rise of CO2 in the atmosphere, but is tolerable for inside air quality measurement, where most rooms ...

For tVOCs and inaccurate, inferred CO2 readings, absolutely. Sensors like the BME680 or SGP30 are ~4mm square. For real CO2 sensors, not yet. The smallest accurate sensor I''ve worked with is the SCD30 and it''s much too large to fit into a watch body asis.
