I currently make use of solar geysers in my home where they are controlled by a Geyserwise device
The geyserwise has a 12v solar pump circulating the water between the tube manifold on my roof and water in the geyser in my ceiling.
The geyserwise has a control panel where you set timers.
The geyserwise has 2 temperature probes.
1 goes into the temperature pocket on the tank and the other into the tube manifold on my roof.
When the temperature in the manifold is 7° higher than the water in the tank, the geyserwise switches on the pump to circulate water. And stops when temp is less than 5.
My question:
Can this somehow be replicated with a TH switch and waterproof temperature sensor?
Can these switches take 2 sensors? Or could 2 TH switches talk to each other in a scene somehow?
The switching on and off of a 220v pump to circulate the water is the easy part.
I want to keep this within eWeLink if possible as I don’t know how to use IFTT etc…
HI. I have the exact same setup, only 2 geysers with 2 geyserwise units. I bought the TH16 with waterproof probe 2 months ago. i fastened the probe to the coldwater outlet from the geyser that goes to the solar manufold. i made the set point 53 C and used the ewelink app for the automation. i later moved the automation to iHost because i bought 1. it has been running with no problems for 2 months. my ON time is 9 in the morning and OFF time is 3 in the afternoon. when the geysers reach that temp they both switch off untill 2morrow.
With the TH 16 you might as well sell the geyserwise to a friend because the ewelink app works great. you can also have an automation that turns on a geyser element if the temp is below 45 in the afternoon, just for an hour or so. just use a relay then that switches the 12volt pump on and off when needed.
Of course, you need to have two temperature and humidity sensor devices, and then set the temperature difference between the two devices as a trigger condition inside 1 scene
