Hi,
We can only provide support on the AD5700 modem itself.
For support on other specific HART registered components, please visit the HART foundation website.
That said, what you could consider is a smart sensor like the CN0267 which incorporates a bridge transducer/RTD sensors, micro controller and loop powered DAC/HART modem.
For your application, you would need to incorporate the light sensor which would not need to HART enabled.

Hopefully this helps.
Kind Regards,
David
