For the past year we’ve had 8 stations using SDI12 CTD sensors and Yosemitech wipered turbidity sensors together on one prototype Mayfly using the EnviroDIY RS-485 half-shield. It also works with other generic modbus adapters too. We’ve had no issues with not being able to read the sensors or with dropped readings. I’m attaching the code below so you can see how I arranged my sketch. I don’t know what modbus sensors you’re using but I assume they are ones already included in our library?
