	RE: Heat Pump Performance Analysis Web App using Modbus Data By cathodeRay, 2 hours ago Forum Air Source Heat Pumps (ASHPs)
	@redzer_irl — I fear we are talking somewhat different languages here. Putting the question another way, is the data in the HA database a reliable indicator of whether a pump is on or off? What is 'in...
	RE: Heat Pump Performance Analysis Web App using Modbus Data By redzer_irl, 2 hours ago Forum Air Source Heat Pumps (ASHPs)
	@cathoderay I added this as I was not able to see the pump operation from the modbus data as it is controlled by the Joule board. The indoor power sensor is a Shelly CT clamp, as is the outdoo...

	@redzer_irl — I am not sure what a 'zone pump sensor' is? Is it a HA sensor sensing on/off state, and if so how does it do the sensing? Ditto the 'indoor power', what is it the power of? The secondary...

	@cathoderay All the analysis is done in Python and AI is not used for this. The logic for the 'Heating during DHW' flag is simple. When a DHW run is happening, the app checks if any heating zones wer...

	@cyrusir I don't want to make generalisations about other systems (maybe people who understand the technical details of Samsung/Joule systems better than me could provide more information) but once I ...
	RE: Heat Pump Performance Analysis Web App using Modbus Data By cathodeRay, 3 hours ago Forum Air Source Heat Pumps (ASHPs)
	As it does for many others, and I even still have my original installation, I never got round to uninstalling it, and my scripts run on the underlying Linux OS HA uses. What I was really saying was th...
	RE: Heat Pump Performance Analysis Web App using Modbus Data By cyrusir, 3 hours ago Forum Air Source Heat Pumps (ASHPs)
	so given i have the same system as you and i have DHW set to run at night (we have an EV as well so are D/N on electricity) should i set my UFH not to call for heat for that first hour where the hot w...

	@cathoderay I understand you don't like Home Assistant but it works well for me. This is my understanding at the present moment from looking at the data and observing the system when operating various...
	RE: Heat Pump Performance Analysis Web App using Modbus Data By cathodeRay, 4 hours ago Forum Air Source Heat Pumps (ASHPs)
	@redzer_irl — very impressive, and I agree with many of your observations (apart from one, which I shall come to). I started out with HA and found, as you did, that it messes with the data. The one th...

	PS by visually merging the two tables as above, I ended hiding your kWh/K column, which does show the values per hour: Attachment : image.png If you multiply the hourly delta t by...
	RE: Setback savings - fact or fiction? By cathodeRay, 5 hours ago Forum Air Source Heat Pumps (ASHPs)
	@adrian — thanks. I'll see what I can come up with. I don't think this is quite correct. The heat loss (and so, when the IAT is stable, the heat delivered to the building, ie the energy out) is direc...

	thank you!
