Geyserwise WIFI module integration (Request)

Jack_Kitley · March 16, 2023, 1:10pm

Ive uploaded a version 2.

Please check if it works for you.

inusbosman · March 16, 2023, 3:58pm

Thanks, it is working now. I can switch Geyser on and off via HomeAssistant and see the temperature, still need to setup the rest.
3 things I’ve noticed, not sure if it is something I’m doing wrong.

Collector temp is not showing
Solar diff temp is incorrect
Pump is always On

Jack_Kitley · March 16, 2023, 4:08pm

Hi. No. Solar diff is max 15.

Something doesn’t look right. Is yours a TSE?

Somethi

inusbosman · March 16, 2023, 4:17pm

Yes, TSE-TUYA. The same as on your photo earlier

Jack_Kitley · March 16, 2023, 5:57pm

And you have outside panel? That’s the collector.

Not sure why your data is off. Pump is also related to the panel outside.

And solar diff.

They are all related.

inusbosman · March 16, 2023, 6:08pm

Yes I do have a collector, currently on 34 Celcius.
I see the new code has “element_hours” added to the published results

Jack_Kitley · March 18, 2023, 5:30am

Yes. Element hours is on newer versions of board it seems. Hence why it wasn’t working as data length changed. 8 bits added.

Is it still not working? I have a friend coming today to collect a panel and he has a TSE from 2016

Will let you know if it works

inusbosman · March 22, 2023, 7:58pm

For me the most important function is being able to switch off and on as well as to be able to read the temperature. Collector temp and temperature difference is not a big issue.

Hi Johann.
Which Sonoff device did you use?
(TH Origon, THE Elite, TH10 / TH16)
Would love to know how it is working out.
I have had a similar idea for a while, but did not know you could use their temp probe with Sonoff smart switches. I want to monitor and control the temp of the geyser based on a schedule, and turn off geyser during load shedding so it doesn’t drain the batteries on the inverter when insufficient PV solar.
I already have a Geyserwise TSE setup on a Thermal Solar Geyser, so probably replace that with Sonoff TH device and a Sonoff Power device to measure the consumption.

Thanks - I did this and its working great. localtuya for local access and fast home assistant access. Normal Tuya app for cloud access (as and when needed). Next step I need to automate my geyser schedule around loadshedding. I have the ESP integration and have the loadshedding schedule in HA. Any tried and testing automation yamls you can share for doing this?

am1234home · March 27, 2023, 3:53pm

I used the history_stats built in integration in home assistant to count the time the element is on, per day. This gives me a run time throughout the day, which I use as a proxy for my electricity spend for my geyser.

Hi,

Thought I would add my setup to the discussion. I also went the route of removing the WBR and soldered a ESP32-C3 in its place. Thanks Jack for the pics showing which pins go where, it was a big help!

But instead pf going the custom firmware route I installed ESP Home and used the tuya component to get the board working. For those who are interested here is my complete ESP Home configuration file.

    optimistic: False
    options:

      1: "Normal"

The baud rate needs to be set at 9600. I tried other values but the component stopped working.

Also if you use the marked UART (RX/TX) pins, these are the same pins that ESP Home uses for its serial logger so you need to disable the logger in the configuration.

This has worked very well for me and I am happy with the results.

I’ve figured this out now - posting incase anybody else is having the same issue.

So the default available attributes are based on “standard instruction” there is an option to change to “DP instruction” which modifies the standard payload and includes all attributes. To do this, you need to go to the device, and select “Configure Control Instruction Mode” then select “DP instruction mode”

Will continue to post my learnings as I go.

viv-01 · April 24, 2023, 2:50pm

what benefit does this unlock?

the_brains · April 24, 2023, 3:43pm

Depends on your setup and how much info you want to control/report on. The standard instruction only exposes 3 attributes, if you want the additional attributes (14 in the case of the Geyser Wise Max) then you need to use DP.

parautenbach · April 27, 2023, 9:37am

Could you list it?

the_brains · April 27, 2023, 6:09pm

On the geyserwise max, Its the same as what @HomeGeorge linked above -

AtoMisE · May 12, 2023, 5:32pm

I came across this post a few days ago. I bought a TSE1 Tuya board and replaced the Tuya module with a ESP-12F.

I am running ESPHome on my Home Assistant and I added the chip to it using code gtb put up earlier.

After installing the board it worked, I could turn on the geyser, check the temperature, set the max temp etc.

After a reboot of the ESP it stopped getting data. I can still manage the ESP fine but no data.

This is what I get.

[19:16:19][C][tuya:041]: Tuya:
[19:16:19][C][tuya:046]:   Configuration will be reported when setup is complete. Current init_state: 0

Logger is disabled

logger:
  baud_rate: 0

UART is setup

uart:

  tx_pin: GPIO1
  baud_rate: 9600

Anyone else having issues with ESPHome?

I resoldered the ESP and it is working now.

I just came across this thread now. I have a geyser wise max so do I just get this PCB and install a new esp chip into it?
