[3.9.0]

This release is based on the latest Espressif/Arduino core version 3. It brings in many memory and performance optimizations. Note it does require the user to manually migrate settings from 3.8.x to 3.9.0.

Added

• user-requested LED blink #3063
• Commands Service that can be called via MQTT or API or used in the Scheduler Service
• option to disable factory reset #3150
• TLS support with 4MB boards without PSRAM
• added eth_10mbit to Network Settings, which forces 10BASE-T half-duplex & autonegotiation off, halving the PHY’s power draw. It’s off by default as it will cause issues on managed switches with a port forced to 100Mb #3213
• cleaner MD5 and firmware uploading in WebUI #3222
• pc0Flow in l/min #3224
• remove HA config for excluded entities #3229
• show system reports the Ethernet status on boards with a PHY, so a failed initialisation or a link that never came up is visible instead of Ethernet being omitted completely. Also shows the loop task's lowest free stack, to help diagnose reboots
• new Application Setting "Automatically check for firmware updates", off by default. When enabled EMS-ESP asks emsesp.org for the latest version once a day on its own, otherwise it only asks when the WebUI wants to show it, so an unattended system never contacts emsesp.org

Fixed

• shunting yard show json
• system/sendmail called from a Command or the Scheduler computed its value twice, which stripped the quotes from literal text and then failed on characters like !. Also shunting yard treated a ? inside a quoted string as a ternary, so text like "too hot?" returned nothing
• memory leak when using different timezones for ems-esp and thermostat#3184
• LED stayed off on a healthy system when "Disable LED" was unchecked
• Ethernet MAC address changed with the new SDK, breaking DHCP reservations (currently disabled)
• "IPv4 nameserver" showed an IPv6 address when IPv6 was in use
• HA Discovery warning on Uptime after EMS-ESP boot due to NTP not ready
• hc/control setting for UI800 thermostats #3181
• solar module switches #3223
• possible crash when the WebUI asked for version information while the versions.json refresh was rewriting the cache from the main loop task
• HTTP client could write past a fixed 64 byte buffer when a URL had a hostname of 64 characters or more, could busy-spin for the whole read budget if the socket reported bytes it wouldn't return, and buffered responses without any size limit
• the "Ethernet clock mode (GPIO16/17) conflicts with PSRAM" error was never logged because Ethernet had already been skipped by the time the check ran
• heat limit entities (maxheatcomp, maxheatheat, dhw.maxheat) read as unknown on heat pumps with an auxiliary heater larger than 9 kW - enum_maxHeat was missing the 12 kW and 15 kW steps

Changed

• various memory optimizations #3083
• Scheduler name is now mandatory
• network fallback to AP only after start #3090
• replaced Web async-validator with custom validator and toast with native snackbar to reduce bundle size
• Gateway and Connect devices are shown in the Devices page, but disabled 3126
• show control setting only for master thermostats (0x10) #3173
• remove devices without entities not listed in 0x07 telegram
• changes to the Dialogs in Dashboard page, removed the run icon in the Commands page. Renamed Execute to Run.
• set None for undefined values in HA val_tpl
• changes in WebUI - remove multiple calls systemInfo endpoint, Vewrsion pages checks for internet connection #3195
• multiple optimization in network, power down WiFi when Ethernet and WiFi nosleep is instant when selected #3213
• TLS buffers (~17KB per HTTPS request) are taken from PSRAM on boards that have it, instead of fragmenting the internal heap
• failed versions.json fetches back off from 5 up to 160 minutes instead of retrying every 5 minutes, as each attempt blocks the main loop for as long as the DNS, connect and read timeouts allow
