Hi Hubitat team and forum users.
I'm Mike from Canada (Qc) and I do HA since X10
With years, I managed to use a lot of modbus devices (RTU & TCP), mostly controlled by 2 industrial plc's (Semaphore) and other slaves/masters.
I'm kind of an old fashioned guy, so don't really like my home controlled through cloud and/or voice assistants (you know them all for sure). my setting is principally wired. I'm really not into jabbering to my lights...
I just purchased Hubitat (not yet received...) because I purchased some Lutron Caseta switches and hub and I saw some reviews saying that Hubitat and Lutron Caseta can work together.
I don't need obligatory to control (all) my modbus devices with Hubitat but this solution could be nice. I tested a lot of software solutions (Jeedom, Homeseer, etc) to integrate modbus devices but I want also to separate security functions, control functions (solar, geothermal, electricity metering) and living functions (lights, music, confort) without going absolutely all-in-one.
So my question: do you have in your working boxes a (future) modbus driver able to connect modbus devices to Hubitat ? If not, is it possible to build it without going crazy ? Is It feasible on our side (what kind of programming) ? Or should I just stick on my Lutron and some Z-wave units ?
I know that modbus is not really security-minded, but I think that a wired modbus ring running into a local (separated) network is probably safer than any wireless connected cloud device. I'm maybe mistaken but I don't think that a random guy will go into my garden to cut some wires and wireshark a man-In-the-middle attack to my modbus devices... A unknown attacker from a far country will probably try to attack poorly protected IOT cams through internet (remember Mirai). Am I wrong ?
Last but not least, excuse my broken english, I'm mostly french speaking.
Btw, I'm an IT guy, so feel free to talk technical with me.
