I was hoping to see some plots of the PID temperature control in action, I'm curious what is the final fluctuation in room temperature with a setup like this.
Thank you for the suggestion! I will try to add some plots if data from winter months is still available in Home Assistant. Based on my observations during winter, room temperature fluctuation is usually ±0.3° C around target temperature, which I consider to be pretty good for a first prototype :)
Great, thanks for the response. I'm using off-the-shelf radiator TRVs (Aqara SRTS-A01) which use some internal PID program based on the supplied actual and desired temperatures and I experience similar fluctuations in room temperature.
