I built a mug warmer using an ESP32 D1 Mini and a spare Prusa XL Heatbed tile with ESPHome. The problem is, that after setting the initial PID temperature in ESPHome, the maximum temperature that I can set defaults to 30°C. I’m using PID Climate (which seems to be the only sort of PID tuning available in ESPHome), and there doesn’t seem to be an option to set the maximum temperature higher than 30°C. Of course, this makes sense in any other normal setting (who wants teir rooms warmer than 30°C?), but I’d love to be able to set the temperature at around 60-70°C, so my drinks stay warm. Wiring up the tile without some sort of PID control results in much higher temps (around 90-100°C) which is too hot for the other parts (printed PETG parts get soft), so that is not an option either, unfortunately.
If anyone has an idea how I can change this, I would appreciate it very much. This is the last thing that keeps me from finishing my project.
