The honest half
Where it falls short
Concrete and checkable, so you can decide whether any of them matter to you. This is the half of a review a vendor will not write about ESPHome.
- ESPHome runs only on supported microcontrollers; the project recommends ESP32, ESP32-S3, ESP32-C3 and ESP32-C6 and advises against ESP8266 for new projects
- Support for ESP32-H2, RP2040 and other newer chips is documented as less mature
- Large displays and some sensors do not work well on ESP8266 because of its limited RAM, which is roughly a fifth of an ESP32

Softwr does not host reviews and shows no star rating for ESPHome, because a rating we did not collect is not ours to publish. What is here is the pricing and platform detail from the vendor’s own pages, limitations we could state concretely, and alternatives a reviewer confirmed people weigh against it.
