This is probably a simple question, but I'm a noob with this... is it possible to monitor a pulse counter and a ModBus enabled sensor at the same time? I've got a WattNode that uses ModBus as well as a metrima gas meter that outputs pulses for kWh's consumed.
Thanks!

depends on the length of the pulses and the details of the sensor. sounds like doable.
Post more infor to get a better answer.
Do you have a datasheet of the sensor?
Specs of the MODbus?
I can't find a datasheet on the sensor. Here's a link to it. It has two pulse outputs, but it doesn't specify much else

As for the ModBus, what type of specs would be helpful? It's a WattNode ModBus. It measures current, voltage, frequency, etc.
UPDATE:
Based on a spec sheet I found, the pulse outputs for the Metrima are "open collector" types and have specs as follows:
Pulse duration 250 ms
Max. voltage 30 V
Max. current 20 mA
