v3.7.0

[3.7.0] October 27 2024

IMPORTANT! BREAKING CHANGES with 3.6.5

  • "ww" and "wwc" has been renamed to "dhw". It is nested JSON object in both the MQTT and API outputs. The old prefix has also been removed from MQTT topics (#1634). This will impact historical data in home automation systems like Home Assistant and IOBroker. To preserve the current value of dhw energy (was previously nrgww) refer to this issue #1938.
  • dhw entities from the MM100/SM100 have been moved under a new Device called 'water'.
  • The automatically generated temperature sensor ID has replaced dashes (-) with underscores (_) to be compatible with Home Assistant.
  • api/system/info has it's JSON key names changed to camelCase syntax.

For more details go to www.emsesp.org

Added

v3.6.4

[3.6.4] November 24 2023

IMPORTANT! BREAKING CHANGES

Writeable Text entities have moved from type sensor to text in Home Assistant to make them also editable within an HA dashboard. Examples are datetime, holidays, switchtime, vacations, maintenancedate... You will need to manually remove any old discovery topics from your MQTT broker using an application like MQTT Explorer.

Added

  • humidity for ventilation devices
  • telegrams for RC100H, hc2, etc. (seen on discord, not tested)
  • names for BC400, GB192i.2, read temperatures for low loss header and heatblock #1317
  • option for forceheatingoff #1262
  • remote thermostat emulation RC100H for RC3xx #1278
  • shower_data MQTT payload contains the timestamp #1329
  • HA discovery for writeable text entities #1337

  • heat pump high res energy counters #1348, #1349. #1350
  • optional bssid in network settings
  • extension module EM100 #1315
  • digital_out with new options for polarity and startup state
  • added 'system allvalues' command that dumps all the EMS device values, plus sensors and any custom entities

Fixed

  • remove command remoteseltemp, thermostat accept it only from remote thermostat
  • shower_data MQTT payload contains the timestamp #1329
  • fixed helper text in Web Device Entity dialog box for numerical ranges
  • MQTT base with paths not working in HA #1393
  • set/read thermostat mode for RC100-RC300, #1440 #1442

Changed

  • update to platform 6.4.0, arduino 2.0.14 / idf 4.4.6
  • small changes for arduino 3.0.0 / idf 5.1 compatibility (not backward compatible to platform 6.3.2 and before)
  • AP start after 10 sec, stay until station/eth connected
  • tested wifi-all-channel-scan (3.6.3-dev4 a-e), removed again because of connect issues
