How to install new version

From Arska Settings

From Arska installation page who can directly install or download software.

Version codes

There can be pre-release versions of the software available for installation. Following markings are used
indicate to the degree of stability of the software:

• alpha First test releases of the version, not for production
• beta Test releases, not recommeded for production
• rc Release candidate
• stable Tested release for production

[Olli69]

If you are using Elering as Nordpool price source there will be communication errors because Elering web site has changed security certificate provider and old Arska versions cannot connect to the site any more. Latest version includes a new CA certificate for Elering web site.

Please update to the latest version 1.1.0-rc2 if Arska cannot get price data from Elering.

[Olli69]

New version beta 1.1.0-beta13 adds possibility to disable server identity check.

You can disable it from Settings /Advanced settings

[Olli69]

Now also available alfa version of Arska which primarily gets prices from Entso-E and uses Elering as backup (EE,FI,LV,LT only) data source - used if cannot get prices from Entso-E. You can test backup feature by giving wrong API key.

If you like to test this 1.1.0-alfa15 , take config backup (like always) before update and check all settings after update. I did some basic testing and it did what I expected, but testing period was short.

[Olli69]

New alfa test version 1.1.0-alfa16 fixes randomly occurred connection (certificate error) issues.

[Olli69]

1.1.0-beta17
Added functionality to the load manager. In addition to current limit (A per phase, momentary) you can set power limit (period average).

Fixes:
HAN P1 Serial energy meters: Error detection functionality and fixes to wrong measurements (randomly occurred in some setups, specially at boot time).

[Olli69]

Newest Arska version 1.3 you can source find in dev-1.3 branch and also on the install page .

Main new features

Supports 15-minute Market Time Unit (MTU), prices and reporting

• Hour based price variables changed to hour average, new 15 minutes variables: 51,52,53, 54, 61 . Before 15-minute MTU go-live date (earliest 11 June 2025) all 4 periods of an hour get the same price
• Dashboard graph in 15 minutes time scale
  Before European 15-minute MTU go-live date (11 June 2025 or later) the price of is given to all 15 minutes periods.

Supports Fronius Gen24 plus inverters, a new channel type

• Communicates with Modbus TCP (port 502) with the inverter
• Charging/discharging profiles can be controlled from the rules and the dashboard
• SoC (State of Charge) visible on the dashboard graph

Price modifier

Price modifier (Settings/Price data) allows to modify prices on selected hours. You can for example add negative price modifier to night hours to indicate cheaper transfer cost. Price modifier takes effect after updating price data from Entso-E/Elering.

Please note that this is preliminary first test version and not recommended to production device - or you should be ready to restore older version if there are problems. Backup configuration before version updates!

[Olli69]

Arska 1.3.0-beta1 published on the installation page and available on automatic installation. Fixes problems with price related variables and some other smaller fixes.

EDIT:
Replaced with 1.3.0-beta2 which have fixed/tuned recovery from wifi problems.

[Olli69]

1.3.0-beta3

• Has more robust HAN P1 message handling
• You can select power (W) or energy (Wh) for dashboard graph.
• With HAN P1 Serial energy meter HAN P1 message (telegram) is published at /api/v1/telegram endpoint (equal to HomeWizard P1 meter). You can read this telegram from another Arska installation (in the same wifi) using "HAN P1 Proxy" energy metering setting.

Edit 16.5.25: new build of beta3 fixes randomly occurring HAN P1 locking error.

[Olli69]

1.3.0-beta4 published

• More robust behavior if price query fails
• Dashboard energy graphs (import/export, production, solar forecast) can be show with 1 hour or 15 minutes resolution

Edit: A glitch in 1 hour resolutions energy graph (effective when minutes are between 45-59) breaking production & import charts. Will be fixed in the next version.

[Olli69]

1.3.0-beta5 published with new features

Open Meteo based solar energy forecast

In addition to the current FMI solar energy forecast (available in Finland), we have added Open Meteo based solar forecast, which is available in whole Europe. See settings

HAN P1 has an optional Telegram CRC check

With the new additional validity checks HAN P1 input is more robust and less sensitive to for example communication errors. Enable CRC on Settings/ Grid Energy Metering.

[Olli69]

1.3.0-beta6 published with bug fixes

• fixed problem with variable 157
• fixed bug (in 1.3.0-beta5) saving solar forecast location (FMI)
• fixed potential stability issue with HAN P1 processing

Terve!

Latasin juuri tuon viimeisimmän 1.3.0 beta 5 version. Itselläni kyseinen versio ei päivitä enää aurinkotuotto ennustetta paikkakunnan mukaan. Valitsen esimerkiksi paikkakunnaksi Akaan niin kyseisen paikan ennuste ei päivity?

[Olli69]

Moro,
Kiitos kun ilmoitit! Tallennukseen oli näköjään tullut pieni, mutta toiminnon estävä bugi OpenMeteo-laajennuksen yhteydessä. Tein nyt saman tein uuden käännöksen 1.3.0-beta6, jossa tuo bugi ja joitain aikaisempi korjauksia mukana. Eli löytyy asennussivulta tai settingsin päivityksistä (voisi olla että siellä näkyy vähän myöhemmin, koska versiot välimuistissa, joka tyhjenee kyllä ESP32:n uudelleenkäynnistyksessä).

[Olli69]

Just a friendly note that if you still have an old version (< 1.3) now it is time to update to the latest version (1.3.0-beta6) to get prices (15 minutes MTU) correctly.

Olen yrittänyt päivittää jo useita kertoja kännykällä ja monella eri selaimella tietokoneella mutta päivitys ei onnistu eikä tule mitään virhe ilmoitusta. Mikähän neuvoksi kun varttihinnoittelu on jo meillä käytössä

[Olli69]

Selaimella ei tässä päivitystavassa pitäisi olla vaikutusta. Jos yhteys on päivityssivulle hidas, niin voisi aiheuttaa tämän. Kestää joka tapauksessa muutaman minuutin. Yleisesti mulla ei havantoa että päivitys ei näin toimisi.
Vaihtoehtoisesti voit mennä Arskan päivityssivulle https://iot.netgalleria.fi/arska-install/:

1. ladata sieltä firmware.bin ja littlefs.bin ja ajaa ne yksitellen Arskaan osoitteesta http://arskan-ip-osoite/update
   tai
2. tehdä päivitys kaapeliyhteydella
   Ja asetukset tietysti kannattaa ottaa ennen talteen.

[anttivaan]

Ok. Eli tuota kautta päivityksen pitäisi onnistua vaikka kännykällä olisi arskan ip osoitteessa?
Minulla on kyllä hidas netti ja vähän pitkät matkat wifi verkossaki. Yritän vielä eri tavoilla mutta piuhan laitto on hankala kun piirikortti on keskuksen sisällä.

[Olli69]

Joo, vain kaapelipäivitys on tarkka selaimesta (Chrome a Edge). Mutta jos yhteydet kovin hitaita, niin tiedosdoen erillislataus koneen kautta voi olla varmempi tapa.

1.3.0-alfa8
This alfa version contains some bug fixes: e.g. price ratio variables 14, 15 data overflow fix and some HAN P1 tuning.

There are a couple interesting new features.

Channel state variables 901, 902... tell current state of a channel. For normal load channels 0 - down, 1 - up. For Fronius inverters, there are more possible profiles/states. You can use channel states in rules (in other channels). For example follow other channels state without copying the rules or defining state switch channels (e.g. home/away) which effects rules in several channels.

Forcing/scheduling a channel down at the dashboard, in addition to forcing up (existing feature).

But please note that this version is not well tested, so use specially new features with caution.

[Olli69]

1.3.0-alfa9 has bug fixes:

• "random" price error from Entso-E, problems with chunked data
• stability error caused reboots in HAN P1 environment
