Congratulations on the new ride, @sinthome and thank you for choosing Discount Tire!
I have a 2nd Gen RX400H and I recently did the same as you by moving one of the tires coming off the vehicle to the spare wheel. I can confirm that the spare assembly does utilize a TPMS sensor.
As previously mentioned, TPMS sensors could be dead. They are powered by a small watch battery and usually have a life expectancy of 7-10 years, so based on the year of your vehicle and the fact that they may be the original equipment sensors, one or more could be dead or very low on battery life.
The TPMS indicator on your dash gives us a bit of information about the issue. A light that stays solid indicates a PSI issue in a tire or tires. If the light flashes and then goes solid this indicates a system malfunction requiring service because the vehicle has lost the ability to communicate with a sensor. If the battery/s have died, the sensor would need to be replaced as the batteries are not replaceable.
Sometimes when sensors are close to the end of their battery life, by removing them from the vehicle and reintroducing them, the sensor attempting to reconnect with the vehicle can take the last bit of life the sensor has. Nothing a shop does incorrectly, it simply takes more battery life to relearn to a vehicle as opposed to simply advising the vehicle a brief data signal of PSI information while driving.
A sure fire way to confirm a sensor issue is to have someone with a scan tool, scan the sensors, this will specify if a sensor is no longer broadcasting a signal.
Please feel free to contact us if you have any further questions, we are always happy to help. I have also included a link with further information that you may find of use.

Got it scanned and sorted out, one "low" battery that I went ahead and replaced. Otherwise I'm loving this car so far. It is quite fast and fun to drive. The hybrid battery doesn't seem to last as long as I expected when parked with the ac running or lights on drains it quickly, although it still recharges in no time while driving so hopefully it is still healthy.
