• Fixed precision on Domoticz energy payload
• Fixed dips on realtime export power
• Fixed filter on SSID name to allow more characters
• Fixed changing from static IP to DHCP
• Fixed redirect to dashboard after initial setup on ESP8266
• Fixed checkbox styling, now showing tick mark
• Increased range for instant power. Fixes erratic power gauge on large systems
• Increased range for tariff thresholds
• Renamed "Configuration" in system info to "Backup & restore"

Fixed GPIO select for HAN on ESP8266

Fixed ADC issue introduced in 2.2.6 causing incorrect voltage read error

• Changed some debugging behaviour
• Changed some code relating to temperature sensor update and MQTT publishing

• Fixed issue where month cost from v2.1 series firmware was incorrectly loaded

• Fixed issue where special character in model number broke user interface
• Fixed display chipset for ESP32-solo

Changes:

• Completely rebuilt user interface
