(fixed) False error when DHW finished

[Alan_Bennett]

Evening all.

I’ve started to add my cascade system onto this excellent platform. Great work all. I’ll add it to public viewing once it’s all running.

I’m using a 2nd pi5 just for emoncms, running on HA. Data is via MQTT from my first pi5 . I wanted to keep the systems separate because predbat runs on my first pi5.

I’m sending live power via esp32 and a pulse sensor. I’m sending that data via API and mqtt. My first pi5 is still being used to monitor my ashp on HA

After a few days playing I’ve got my first graph. Nice. Luckily DHW was running so I could monitor for any issues.

When the DHW finished i got a false positive for air in the system. Is this something I have to live with or can I change settings within emoncms to ignore the ASHP powering down?

The other minor issue is the max power spike. I’ll change the esp32 Yaml to clean up the data.

I’ll added the secondary ASHP in the next few days. For the cascade part of the system I’m not 100% sure what data to display to represent my system when both are running.

What’s the minimum I need to record meaningful data via a cascade system ?

It would be marvellous if there was cascade template that I could drop all my sensors into emoncms.

Thanks.

Evening. All fixed. I had to x1000 on the heat output feed.

I’ll add a 3rd set of data into emoncms combining both ASHP.

Thanks.

Morning.

Sorry I’ve been upload and deleting my systems on the league table. I’ve final found the reset button for all data. I’ll upload again when I’ve collected DHW data without errors.

I’ll have primary ashp 1 that does DHW plus heat when the logic decides.

The secondary ashp 2 will be for heat only.

The cascade has combined sensors but uses the rest of the feeds from the main DHW ashp. I’ll then be able to include DHW data plus both running when heat is required.
