I currently have an IPS-M820 + 2x Rola-Chem RC103SC + 2x 7gal buckets (one acid, one chlorine) setup for pH/ORP. It has been great over the last ~5 years, requiring essentially zero effort/maintenance other than adding more chemicals to the buckets. My only complaint with it is that I have zero remote monitoring or logging capabilities (no website, no integration with my Jandy RS8/iAquaLink, no logs)... so, now I'm looking to change it 
Given the setup with the 2x Rola-Chem pumps, it seems the options are:

Given the setup with the 2x Rola-Chem pumps, it seems the options are:
- Jandy C1900 - discontinued, but can control separate pumps and uses the same probes. Gives remote monitoring capabilities, but no logs/history data
- Jandy TruDose - only has a built-in pH pump and would require I go to a SWG for chlorine ... not really an option.
- IPS-M920W - Drop-in replacement, provides web-based programming, monitoring, reporting, and alerting (text/email)... but no integration into Jandy
