* reduce last_success MQTT messages (#1124)
* add re-request if inverter is known to be online and first try fails
* add alarm reporting to MI (might need review!)
* rebuild MI limiting code closer to DTUSimMI example
* improved RSSI for NRF24, now it's read per package (and inverter) #1129
* arranged `heap` related info together in `/system`
* fix display navi during save
* clean up binary output, separated to folders
* fixed docu #1085
* changed active power limit MqTT messages to QOS2 #1072
* improved alarm messages, added alarm-id to log #1089
* trigger power limit read on next day (if inverter was offline meanwhile)
* disabled improv implementation to check if it is related to 'Schwuppdizitaet'
* changed live view to gray once inverter isn't available
* added inverter status to API
* changed sum of totals on WebGui depending on inverter status #1084
* merge maximum power (AC and DC) from PR #1080
* MqTT alarm data was never sent, fixed
* REST API: added alarm data
* REST API: made get record obsolete
* REST API: added power limit acknowledge `/api/inverter/id/[0-x]` #1072
* merge PR #1056, visualization html
* update MqTT library to 1.4.4
* update RF24 library to 1.4.7
* update ArduinoJson library to 6.21.3
* set minimum invervall for `/live` to 5 seconds
* restructure serial debug output (partly)
+ MI - more code review
* fix debug output for power control cmds
* MI - limitation commands answered
* Debug - add more macros and texts
Might as well help for https://github.com/lumapu/ahoy/pull/478
Unfortunately, this atm doesn't really lower used flash memory
* MI - limit command
- now seems to work for MI-600 (to be verified)
- debug - more use of macros (wrt. to real effect see last remark)
reduced maximum allowed JSON size for API to 6000Bytes #660
small fix: output command at `prepareDevInformCmd` #692
improved inverter handling for MQTT #671
added part of mac address to MQTT client ID to seperate multiple ESPs in same network
added dictionary for MQTT to reduce heap-fragmentation
removed `last Alarm` from Live view, because it showed always the same alarm - will change in future
fix blue LED lights up all the time #672
fix installing schedulers if NTP server isn't available
improved zero values on triggers #671
hardcoded MQTT subtopics, because wildcard `#` leads to errors
rephrased some messages on webif, thx to @Argafal#638
improved `isAvailable`, checkes all record structs, inverter becomes available more early because version is check first
fix tickers were not set if NTP is not available
disabled annoying `FlashStringHelper` it gives randomly Expeptions during development, feels more stable since then
moved erase button to the bottom in settings, not nice but more functional
split `tx_count` to `tx_cnt` and `retransmits` in `system.html`
fix mqtt retransmit IP address #602
added debug infos for `scheduler` (web -> `/debug` as trigger prints list of tickers to serial console)
