“Bought this to experiment with Home Assistant on pi5 installed by Rpi-imager, with a Sonoff TRV. Good news all installed 1st time - NO APP required. Only slight snag was that I wasn't reading the TRV docs literally enough. They are somewhat cryptic. The valve HAS to be on a radiator to pair as it tries to see if it is fitted before it will do anything else. Perhaps the pimoroni web page could mention these points for potential customers?”
