Quick "time-remaining" sensor for ESPHome

This is a quick and dirty cut/paste from an old ESPHome project that I never got around to writing up. It monitored several sensors and controlled a hydroponics system.

The specific snip above creates a text string that is published back to Home Assistant.

Hopefully it should be pretty easy to figure out what's going on.

The time remaining depended on several factors and could change arbitrarily. For this reason, I found it much simpler to update the time remaining sensor from other entities/components which is why the update_inteerval is never.

Decoding modbus data from generic chineese PH Controller pH-1800
"""
This is a simple script to communicate with a "generic" ph / ORP controller as seen on Ali Express
The listings for these devices will usually have a title like:
PH Controller pH-1800 Industrial On-line Ph Meter Electrode pH Tester Transmitter
E.G.: https://www.aliexpress.com/item/32993041598.html
The only documentation that I could get from the seller is a microsoft word file and a microsoft windows program that appears to
need an older copy of 32 bit windows. I was not able to get the program to run in a VM to sniff the modbus traffic and a quick look
