Related, is anyone aware of an affordable OBD hardware simulator? The ones I found are either pretty expensive (e.g. https://freematics.com/pages/products/freematics-obd-emulator-mk2/ https://freematics.com/pages/products/freematics-obd-emulato...) or seem sketchy (e.g. https://de.aliexpress.com/item/OBD-simulator-OBD-development-and-testing-tools-ECU-simulator-MINI-version-301/32794172958.html https://de.aliexpress.com/item/OBD-simulator-OBD-development...). I am also aware of https://github.com/carloop/simulator https://github.com/carloop/simulator. However I would prefer a one piece solution. Any tips?
