TuyaMCU Support for PH-W218, multiple unknown DpId

[mjschrod]

It is about the Yieryi PH-W218 smart meter for pH, ORP, TDS, Temperature, ...

I replaced the CB3S with an esp8266 and flashed tasmota on it. The only DpId from the serial protocal that is recognized is the one for temperature (8). All other DpId respresenting:

8: temp_current
101: sensor_list
102: temp_warn_max
103: temp_warn_min
106: ph_current
107: ph_warn_max
108: ph_warn_min
111: tds_current
112: tds_warn_max
113: tds_warn_min
116: ec_current
117: ec_warn_max
118: ec_warn_min
121: salinity_current
122: salinity_warn_max
123: salinity_warn_min
126: pro_current
127: pro_warn_max
128: pro_warn_min
131: orp_current
132: orp_warn_max
133: orp_warn_min
136: cf_current
137: cf_warn_max
138: cf_warn_min
141: rh_current
142: rh_warn_max
143: rh_warn_min

are unknown.
(from https://www.elektroda.com/rtvforum/topic4061780.html)

The Min and Max are not that relevant for me, presumeably for most other users too. But the "_current"-values are of interest.

I am not really familiar with customization nor coding of Tasmota-Drivers. Perhaps I would master it one day.
Nevertheless, I believe that here are some very experienced contributors, for whom this is an easy task.

I can contribute at first a protocol:

The values needs some calculation (cite):

ID	Function	Unit	Display	Data value	Calculation
8	Temperature	°C	28,300	283,000	/10
106	pH	pH	6,840	684,000	/100
111	TDS	ppm	154,000	154,000	1
116	EC	uS	308,000	308,000	1
121	Salt	ppm	179,000	179,000	1
126	S.G.		0,996	996,000	/1000
131	ORP	mV	-1123,000	-1123,000	1
136	CF		3,100	310,000	/100

Secondly I can do some testing.

Thanks in advance. :)
