Activity for alphaess-esp32
-
Danny Backx committed [r143] on Code
Better error handling in some places.
-
New algorithm, very simplistic, to determine when to charge from the grid.
-
More cleanup after OpenMeteo integration
-
Clean up logging
-
update
-
Remove dead code.
-
In the process of replacing the geolocation module (sunrise/sunset) with OpenMeteo, which
-
Add https://open-meteo.com as a server, this can replace and improve several others we use.
-
Also query weather before the configured hour; and don't charge if already at/above target
-
Show more info about sun prediction on ext webserver too
-
Tweak one of the defaults.
-
Simple change to get our dates in line.
-
Fix issues with formats for floats.
-
Test for no sunshine data, and log if that happens
-
A bit more error detection after seeing a nearly endless list of Sunlight tomorrow (2026-02-23) : -1
-
Fix the test to stop charging at soc_target, I think
-
Especially soc_target should be persistent (not inside the loop as it was).
-
Tweak algorithm a bit.
-
Fix mdns name issues
-
Implement code to support buttons at the bottom of the view?status page.
-
Fix condition on honouring cutoff
-
Remove a rather senseless piece from the report, add another.
-
Allow bad weather forecast to break the cutoff hour setting
-
Tweak logging
-
Cope with tm_mon being off by one
-
Updates
-
Updates
-
Changes to support dual build, as described in https://github.com/espressif/esp-idf/blob/master/examples/build_system/cmake/multi_config/README.md
-
Indenting only
-
Implement experimental stuff to cope with the weather prediction influencing loading from the grid.
-
Remove throttling stuff, we already determined not to query more than once a day.
-
error handling
-
Extend WeatherAPI to something that appears to work, call it from the app.
-
Experimental support for calling the WeatherAPI to get a prediction on amount of sunlight
-
Now the simplistic algorithm to find the cheapest period doesn't look beyond the cutoff hour.
-
First cut at making this season-independent.
-
Add a couple of buttons on the HTML page, so the user can start and stop charging.
-
add screenshot
-
add screenshot
-
Forgot copyright update for this year
-
Changes to make the app run in read-only mode, so allowing a test device next to the production one.
-
Logging changes (mostly re-enable).
-
Update
-
Add method for externally visible Web page, start a second Web server
-
A bit more comment.
-
Better float format
-
Less logging.
-
Limit the algorithm to operate on hours before a cutoff
-
Reduce logging.
-
comments
-
Overrule the otaOngoing method as described.
-
Small improvement: avoid fixed size memory allocation.
-
Basically integrate my Ota class, while updating it a bit.
-
Avoid code duplication, use doCall() in connect() also.
-
Don't have those variables in a build with the components locally
-
Add icon for web server.
-
update
-
Update
-
Add to Readme.md
-
Add summary in the Readme.md
-
Add license statement
-
Fix
-
Fix for component in the registry
-
Create file for component registry, fix CMakeLists.txt
-
Add license file
-
Add file for component registry
-
Add original CA Cert file, not just the symlink
-
Implement HomeWizard /api/system
-
Implement /api/measurement call to the P1 energy meter
-
Add component to talk to HomeWizard P1 energy meter
-
Add (work in progress) component to query a HomeWizard P1 Energy Meter via its v2 API.
-
Add an alternative algorithm, not sufficiently tweaked yet
-
Implement a second algorithm. Not tested thoroughly yet. Also best accompanied with variable charge rate, which I
-
Summarize algorithm parameters when running it
-
Clarify values mentioned
-
Fix some of the time variables.
-
Fix URL
-
Fix URL
-
Add remark
-
Update
-
Add Readme.md file for AlphaESS.
-
Bugfix : local variables were masking class members.
-
Remove stale variables
-
Entsoe : protect against using old data.
-
Several bugfixes
-
Implement a missing case in the business code.
-
Move AlphaESS and modbus classes into the component tree
-
Move old (cloud platform based) code out of the way.
-
Add background task (which we always said we should).
-
Add syslog class, and small App fixes.
-
Revert some of the logic to avoid returning from the function in the middle.
-
Bring entsoe and AlphaESS stuff together, don't actively steer yet (only send log messages).
-
Add API to query SOC %
-
Implement more APIs, build a status web page
-
Tweak logging
-
Mostly use mDNS to allow user to find the device
-
Implement experimental code to set charging period.
-
Don't free the reply buffer twice.
-
Cleanup after moving writeMultiple to the modbus class.
-
Implement writeMany in the modbus class where it belongs.
