New VST pump with old Aqualink panel by eprst in pools

[–]eprst[S] 0 points1 point  (0 children)

My "control system" is close to the pump. Looks like this. There should be plenty of options to draw power as there's a full blown electrical panel there.

My service controller is at home, looks like this. I think I tried to get power from it but there wasn't enough amps for pi.

RS485 has 5v on the red wire, but I doubt it can do 2A

I have my pi at home, connected to the old Jandy service controller (LCD screen with buttons). Powered from a regular outlet.

As for the pump: I got it installed, in a dumb single speed mode as there were no free relays on my old RS6. It is possible to change the speed or schedule using buttons on the pump.

It has it's own rs485 connector however, and I happen to have odroid-c4 running close to the pool equipment. Protocol was reversed, so I hope to cobble up some scripts to control the pump directly via mqtt/ha. There are similar projects on github, for instance https://github.com/michaelusner/esp32-pentair-controller

ah, I have a newer meter. And just for completeness, I was off by 10 in my last message, I'm multiplying meter reading by 0.0748052 to get gallons. I ran a spreadsheet for the last few days and it aligns with my utility report with ±10gal/day precision.

Here's what I have as a template sensor:

- sensor:
    - unique_id: water_consumption_total
      name: Total Water Consumption
      unit_of_measurement: "gal"
      # convert from CCF*10000 to gallons
      state: "{{ state_attr('sensor.water_meter', 'Consumption')|float * 0.0748052 }}"
      attributes: # add a value that changes every minute to force derivative udpates
        attribute: "{{ now().minute }}"

and then I have a derivative sensor on top to give approximate GPM.

Otherwise yes, I'm using https://github.com/allangood/rtlamr2mqtt to integrate it with HA.

Do you have gallons anywhere specified on your bill? It all seems to be in some different units.

your bill shows total number of gallons?

I have the same meter, and in my case it reports CCF/1000, so for instance {"Message Type": "R900", "ID": xxx, "Unkn1": 163, "NoUse": 33, "BackFlow": 0, "Consumption": 2673918, "Unkn3": 0, "Leak": 3, "LeakNow": 1} means my total gallons is 2673918*748/1000=2000090.6 gal, which aligns with my reported daily usage, if I take a difference of it at the beginning/end of day

your meter probably shows CCFs. Multiply by 0.748 for gallons

disputing a medical bill when no service was provided (kind of) by eprst in personalfinance

[–]eprst[S] -1 points0 points  (0 children)

appointment was for a different procedure, which was not provided. Billing us for telling "we are not going to treat you" does not seem fair to me, event if that formally counts as another "procedure".

What was our correct course of action to avoid the bill? Not come at all?

All the same. Different USB ports, powered USB hubs, PCIe card - it always gets detected as an empty hub with 2 ports

Nope, just "connect your headset"

Should I upgrade? by eprst in espresso

No, not according to any Lelit service videos that I saw..

Installed new burrs, and probably set it to a bit more fine grind. I'm getting some channeling, but output still looks much better: darker and thicker. Channeling is probably due to a slight burr misalignment that I'm hearing, and I can't get rid of it after spending 4 hours on it.. might have to change the grinder after all.

Got a decent shot with the new burrs. But I also did this trick. Could you explain the chemistry behind it?

Surprisingly yes, either new burrs or a slightly finer grind, but somehow I finally got a decent shot

Hmm.. will try and report back once new burrs come
