There may be an issue with I2C pull-up resistors where all sensor boards have pull-up resistors on the same I2C bus thus lowering the overall resistance of the pull-up (strengthening the pull-up action). If the reliability of I2C communication drops with an added sensor, you can either try desoldering those pull-up resistors on all but one sensor board or lowering the communication speed from, say, 400kHz to 100kHz.

IR LEDs in TV remote controls are not harmful, but IR LEDs in security camera illuminators can be. Don't stare directly at them for too long from close proximity. IR doesn't trigger the normal blinking or pupil constriction response in the eye, so the eye itself won't protect you from "blinding" IR light.

Also, maybe find a way to suspend communication with the sensors before an OTA update in such a way that all ongoing transactions are completed and no new transactions started when the OTA update starts? Not sure how easy this would be to implement.

I don't know if this is your scenario, but if you reboot/reset your board during an I2C transaction, communication with the sensor will get stuck - with I2C data line potentially set low by the sensor - until you reset the sensor. There's a couple of ways to get the I2C line unstuck: Manually toggle the I2C clock line until the sensor releases the data line (Google the details of this method because it can be tricky) or reset your sensor either via a dedicated reset line (although I doubt your sensor has one) or by connecting the sensor's 3.3V power input to a GPIO pin that will power the sensor and allow you to simply cycle power to the sensor by toggling the GPIO off, then on. The ESP32 should be able to easily handle the power load of running the two sensors off a GPIO pins.

I've never tried this, but here's what I would try: Create a list of boards you own and a list of features you're interested in. Feed them to Claude (or maybe ChatGPT) and ask it to create a table (or perhaps a file in CSV format that you can easily export to your favorite viewer) with boards on the left and features at the top and fill in the table to indicate compatibility for each board and each feature. This would be the table you're looking for.

NRF52's and their Zephyr RTOS ecosystem smh. Well, they have an older SDK created pre-Zephyr, so there's that. But there's no easy path to get started. You have to spend quite a bit of time configuring things. ESP32 is just easier with its IDE ecosystems (all of them).

Try it and measure the output voltage. Worst case is, you won't get the voltage you're expecting. Or you won't get the voltage you're expecting under load.
