I have an emonHP install with an existing RF emonTH in my living room. I’ve purchased 2x additional emonTH sensors (and the FTDI programmer to re-configure them for 433MHz). I have configured the emonHP with these nodes and their readings are showing up in the log as well as the emonHP Inputs page.
I would really like these to show up as room feeds on HeatPumpMonitor HeatpumpMonitor.org. I can’t see or find how to configure it to show them. My emonHP install does not show up in my user account. Do these come pre-configured with a service account to simplify install?
My ultimate goal for all this work is to optimise the heat pump cooling mode on my fan coil circuit. The existing sensor will continue to live in the Living Room, the two new sensors will go into two of the rooms with fan coil units. With a flow temperature of 10º I see the compressor run once then shutdown indefinitely (I believe due to not achieving the dT 3K needed to trigger a restart). With a flow temperature of 5º I see the compressor cycle very aggressively resulting in an EER of ~1.4 when I would hope for something in the region of 3 to 4.5.
I can’t help you very much here, but I want to point out that you have two entirely separate instances of emonCMS and two accounts, one running on the Raspberry Pi in your HeatPump Monitor, and an account on the shared emoncms.org. HeatPumpMonitor.org gets its data from the latter.
Thank you! That was helpful, I finally had the time to look at this again and based on your post I was able to created 3x feeds on my local emonpi for the devices so that I can graph them. I should be able to compose the dashboards I need to figure out this optimisation.
OK, this sounds a good start. I don’t have a heat pump so this is the reason I can’t be a lot of help, however Heat Pump Monitor is very closely based on a standard emonPi (both the old and the corresponding ‘new’ version of both) but at the the same time there are detail differences. So you should have little difficulty in following the documentation for emonCMS to add graphs, dials etc for the new temperatures, and it might even be possible in the future, using something like the integration with Home Assistant which colleagues here are working on, to control the heat pump using those new sensors. For example, you might be able to take a straight average, or a weighted average, or just take a maximum or minimum of the three temperatures as an input signal.
