Is it possible to connect multiple sensors to the single UART pins available on the CC2530 chip, or is a cc2652 chip required so each UART sensor can have its own set of configured pins?

Specifically, I want to combine a Senseair S8 CO2 sensor with a PMS5003 2.5 particle sensor, to make something like a Zigbee AirGradient.

If only one UART sensor were supported on a CC2530, a third option would be to use a different CO2 or particle sensor, but I’d like to confirm how many UART sensors this firmware on a CC2530 chip will support before going that route. Thank you!

hi … just for sharing about PZEM on HOME ASSISTANT.
i’ve added these lines in config yaml
the “Frigo cuisine” is the name i’ve set in zigbee2mqtt
