This will allow to not remove discovery topics during each ems-esp restart (MQTT init), so it can solve issue #910. After applying this fix (and removing from the code commands that delete discovery topics) HA no longer reports errors/warnings in the log. I'm testing if for over a week. Now it is enough to delete discovery topics only when it is really needed (e.g. the entity has been removed by customization, discovery prefix has been changed or the HA option has been disabled in the configuration).
EMS-ESP is an open-source firmware for the Espressif ESP32 microcontroller that communicates with EMS (Energy Management System) based equipment from manufacturers like Bosch, Buderus, Nefit, Junkers, Worcester and Sieger. It requires a small gateway circuit to interface with the EMS bus which can be purchased from https://bbqkees-electronics.nl or custom built.
Features
- A multi-user, multi-language secure web interface to change settings and monitor incoming data
- A console, accessible via Serial and Telnet for more advanced monitoring
- Native support for Home Assistant, Domoticz and openHAB via MQTT Discovery
- Can run standalone as an independent WiFi Access Point or join an existing WiFi network
- Easy first-time configuration via a web Captive Portal
- Support for more than 110 EMS devices (boilers, thermostats, solar modules, mixer modules, heat pumps, gateways, switches, heat sources)
