Geyserwise Tuya

Curious to know what people have their solar differential temperature set to if you're using an evacuated tube system?

Now that I have all the data I can see the system kind of plateauing in the low/mid 30s most days even though the collector temp gets heated quickly. Had my differential temp set to the default 7C but experimenting now and raising it to 10C, testing to see if it makes a difference at all.

Only thing I can think of is that I'm getting too much loss between the collector and the geyser, so maybe raising this might work better, at least in winter.

Have graphed this showing the trend:

The Geyserwala Connect is known to work with the MAX and TSE1. Recent testing by enthusiastic customers with Delta-T has not shown any issues, so looking very good.

I can Confirm
Have been running the Geyserwala for about 2 weeks.
As I use HomeAsistant for all my integrations, this so far is a great fit, and a improvement over the Tuya.
It perfectly fits into HA , MQTT (some small issues)
  1. Integration into Home assistant is working perfect.
    1. I have Only one Timer set for 03:30 to 06:00 at 43 degrees
    2. I have set the setpoint at 65 degrees
    3. Created a Automation in Home assistant.
If I have solar production during the day, and the Batteries are charged to 100%, I then Automate Boost
  1. This needs some tuning, to also take the Collector temp into consideration
  2. This actually means then that by 03:30 the temp is still at 53
Must also add that feedback and response from geyserwala is instant, and they listen to any suggestions.
I think this will turn into great product.

Did you previously have the Tuya Geyserwise?

I'm just now seeing I can make my TSE1 smart, somehow missed the launch last year. So I'm keen to get the new board. But now not sure the Tuya version or Geyserwala. I do prefer MQTT and I don't have any Tuya stuff so leaning more towards that

Yes I had the Tuya, but hate that integration with HA.
The Geyserwala is working like a charm in HA, with automations, and Graphana for graphs.
It is far better than the Tuya. ecpecialy with additional features , and the times makes much more sense.

I have been struggling to get MQTT to work though , but that may be as I use HA as broker.

What are the additional features? I'm looking to upgrade my geyser to some form of smart device and basically only need the ability to turn it on/off based on temperature via HA.

Are both options able to do this?

Why make it smart if all you want to do is, turn on/off based on temperature? The current thermostat already does this. That said, I am sure you can do this with both. The choice between them is, whether you want to deal with tuya (geyserwise) or not (geyserwala). That said, I vote for the latter, its great to see a local startup focusing on Home Assistant but it can also work standalone without home assistant.

I want to be able to dynamically set the thermostat temp so that I can store excess PV energy in the geyser. The current thermostat doesn't allow for easily changing the temp. My current CBI Astutes are running on localTuya with no issues, but I'm more than happy to support a local startup instead.

See now that is more accurate to what you need.

Geyserwala then.

I am very uncertain if tuya allows you to set the temp on the geyserwise. In fact, I think you can see the temp, turn on and off, but not sure if you can set temp/schedules.

That's the problem with these things, you never really know until you test it. I'd be pretty bumed if the geyserwise doesn't allow you to turn it on or off via the wifi though.
 
what I heard from the boost, that is awesome, because you can turn on the boost, which on demand run the geyser up to the temp, then turns off. Will make automations easier.

My Geyserwise TSE does this. It runs on Tuya (I haven't converted it to local yet but it should be straightforward if you already know how).

The geyserwise can operate via timers without wifi, and it lets you set the temperature for different times of the day. Currently I have HA switch it off when there's load-shedding or when other things are using over a certain threshold of power. So I don't use geyserwise's timer functionality, but I do use its built-in temperature control for steadily increasing the temperature through the day as there's power available.

Could you post a screenshot of the equivalent screen Tinuva posted above? I.e. which sensors/controls does it give?
 
This is what I see:1690444001611.pngIt tells me the on/off, and the current temperature.

Note, that even if you put the geyserwise "on", it still decides by itself whether or not to turn on the element, based on the temperature. Just like a normal geyser thermostat once you switch on the breaker.

Not terribly sophisticated perhaps but it does what I need it to. I haven't tried making any decisions based on the temperature. Maybe localtuya would expose more functionality.

Are you able to set the temp for each time zone over WiFi?

Ye you can. The only thing I can't do is set the on-board timer. I just haven't mapped the holiday mode function (but I do believe it is available to use).

ya that on board time one is odd even not available on the Tuya app - I've completely disabled that anyway and just set times / monitors on the scenes option

Yep I mentioned earlier in another post that setting the onboard timer doesn't really make a whole lot of sense when you're already using HA, it will just interfere with the automations.
