Viron Astral Pool ChlorinatorGo integration

Interestingly mine has been fine. I’ll keep you posted.

nagyOUT · February 21, 2024, 2:22am

hows yours going the last few days?

Rhomax · February 21, 2024, 9:06am

After saying mine only fails every few days… it’s now failed for the second time today

zappoo · February 22, 2024, 6:00am

Yep. Failing a couple of times a day too.

zappoo · February 25, 2024, 6:04am

I assume no progress with any sort of fix? No way we can force the chlorinator to reboot every 24 hours?

nagyOUT · February 28, 2024, 4:01am

nah, unfortunately no fix as of yet. I’ve tried a few different things, nothing has improved the random hangup of the halo’s ble.
If only we could roll back to firmware v1.3.

I tried building an automation alert message, triggered by the Halo sensor becoming “Unavailable”, but it has never triggered for some reason.

alias: "Alert: Halo BT Failed"

      - sensor.hchlor_info_message

Small update: Power cycle the Halo will reset the Bluetooth connection.

I put a Wifi switch plug on the Halo power inlet.

Now to work out the automation script…

pbutterworth · February 28, 2024, 10:22pm

Try changing
Unavailable
to
'unavailable'

Doesn’t make much sense, but other have reported success with this.

TimU · February 28, 2024, 10:44pm

Thanks, I’ll try that and report back

Mark.sydney · February 29, 2024, 9:45am

Did you ever work out a way to connect it to HA? I have the Halo Chlor 35 and im stuck

Thanks Paul, that works!

Trigger when the Halo is unavailable for 5 minutes.
Send a mobile notification.
Turn the Wifi switch off
Wait 30 seconds.
Turn the switch on.

Not sure what’s going on but today my ChlorGo can’t be connected to via WIFI. BT works, and the BT ESP proxy works. But in the ChlorGo app, the green dot doesn’t appear (sometimes does, but then fails to connect).

The ChlorGo itself is connected via ethernet. Got an IP address (which i can ping from my laptop)… the “test” works except the last time “Remote Server Connection”… Sounds like a ChlorGo issue maybe??

I’ve also tried via WIFI, also tried rebooting etc.

TimU · March 3, 2024, 1:50am

It’s not just you. Mine is doing the same thing today.
Was working fine last night.
Must be an outage at Fluidra end.

zappoo · March 3, 2024, 7:45am

Seems to be back to normal now.

zappoo · March 3, 2024, 10:00pm

Maybe too early to say, but since the ‘outage’ yesterday, my ChlorGO hasn’t gone “Unavailable” at all…

TimU · March 4, 2024, 1:06am

Now that we have Home Assistant integration (thanks Paul & Daniel!) I wanted to start tracking and alerting some of the the manual items needed to maintain my pool.

I have created a GitHub repo where I will track any updates or bug-fixes as I go.
GitHub source < here

Cumulative Acid Dosing Over Time

Problem Statement

I wanted to know when the acid drum for the peristaltic pump is nearing empty.

My pool acid is automatically fed by the Halo’s peristaltic pump from a 5L drum next to my pump-house, but there are no warnings or notifications about the drum being empty or nearing empty.

The Halo tracks acid dosing via the sensor.hchlor_dosing_pump_today_ml sensor, which measures the amount of acid dosed in a calendar day.
However, this sensor resets at midnight so it does not track cumulative acid dosage over time.

Requirements:

Track and show cumulative volume of acid dosed over any period of time.
Show how much acid is still available in the drum.
Allow me to define the total volume of the acid drum. Default to 5L but allow any volume.
Create an alert (push/mobile/email) when the acid drum remaining volume drops below a certain level. e.g. 1L remaining.
Allow me to reset the cumulative volume counter when I refill the acid feed drum.

Bonus features:

Show the average daily acid usage over the last 1, 3, 7 and 30 days.

Method

Sensors and Entities:

Create input_number entity to store cumulative acid dosage each day from the HCHLOR default sensor.
Create input_number entity to store total drum volume.
Create a Statistics sensor to calculate average daily acid usage by the HCHLOR default sensor.
Create a Template sensor to show how much acid is still available in the drum.
Create a Template sensor to show Average Daily Usages: 3, 7, 30 days.
Create a virtual button that will reset the cumulative volume counter when you refill the acid feed drum.

Automations:

Update cumulative acid dosage each day.
Reset the cumulative volume counter when the virtual button is pressed.
Alert when the acid drum remaining volume drops below 1L.

Dashboard:

Create a Lovelace Card that tracks everything with a button to reset the acid volume when refilled.

v1.1, 4 March 2024, Updated pool_acid_remaining sensor to include the running dosage of today in the calculation. Thanks @zappoo.
v1.2, 5 March 2024, Fixed Cumulative counter reset to zero on HA restart. Removed initial: 0 from Cumulative sensor. Thanks @zappoo.

zappoo · March 4, 2024, 5:25am

Love this!! Only thing i’d say is your pool_acid_remaining should also deduct today’s acid dose, ie i’ve added the 3rd operand to the subtraction:


      pool_acid_remaining:
        friendly_name: "Pool Acid Drum Volume Remaining"
        unit_of_measurement: 'mL'
        value_template: "{{ states('input_number.pool_acid_drum_volume') | float - states('input_number.pool_acid_cumulative_dosed') | float - states('sensor.hchlor_dosing_pump_today_ml') | float }}"

zappoo · March 4, 2024, 5:27am

Also how do i set it so the cumulative is set to 3000ml for now, given i’m guessing that’s how much has been used? I can set this via dev tools, but it gets wiped out on restart?
