I was thinking you could sandwich a strain gauge between the rim and tube. Small coil and some electronics. Power it from a magnet mounted to the chassis. Google search someone actually tried something similar. https://gigazine.net/gsc_news/en/20130110-btps/ |

For live monitoring you are probably best off with that sram unit. There are some non-live sensors as well, similar to the one joeqsmith linked above using NFC: https://www.bikeradar.com/news/tubolito-tubo-mtb-p-sens-inner-tube/ https://bikerumor.com/exclusive-rover-psicle-wireless-tire-pressure-monitor-is-accurate-tubeless-battery-free/ Are you using TPU? https://www.bicyclerollingresistance.com/specials/tpu-inner-tubes |
