Good opentherm gateway
For OpenTherm Gateway Arduino shield
Product works as described, clean board with good indications and general documentation. My recommendation is to buy the kit, soldering SMD is tricky without experience and an error is too easy to make with possible dire results for the board (happened to me, not the fault of the author).
Software library was easy to adapt to my ESP32 (support will most likely be incorporated into next release). Responsive and helpful owner.
Documentation for testing needs extensions for 3.3 Volt case, most likely will be addressed after my feedback.

Great christmas tree decoration
For Arduinoflake
Had really fun soldering this kit together! There are two hard parts - the USB-to-Serial chip and USB micro connector. I had butchered the connector, but luckily had a spare one.
We put it on the top of the christmas tree and everyone commented, how nice it is.
I can highly recommend it!
The patterns are nice and the snake game is quite challenging :)

Perfect, WYSIWYG
For Arduinoflake
I hanged it in the window for Christmas. I would appreciate explanation of how to power it using AAA batteries. I know it's possible in theory, but don't know how, so I used usb cable, but it's a bit ugly :) I used the option to have it fully assembled, bc I'm lazy and don't have any tools anyway. I plan to try reprogramming it during long winter evenings. It was perfectly crafted I really like it. Thanks, Jirka!

Gateway shield works -also on wemos esp8266 !
For OpenTherm Gateway Arduino shield
With some support of Jiri I managed to get the gateway up-and-running on an esp8266 wemos mini pro d1!
The advantage of the wemos in comparison with arduino is its low cost, size, speed, power usage and standard wifi functionality including an option to add an external antenna. ( e.g. https://www.hobbyelectronica.nl/product/wemos-d1-mini-pro/ )
To make this work I ordered a arduino proto board to click in the gateway shield and solder it to the wemos. Some small adaptions on the shield make it work on the 3.3V platform of the esp8266.
I managed to see every command the thermostat sends to the boiler and I can capture the feedback of the boiler.
My next steps are
- add display to wemos to see current state of the boiler, thermostat, and show connections are good.
- use the wifi link the data to my sql database running on my NAS (I know this works already)
- readout 2nd thermostat (on/off) via input and enable boiler via the opentherm
- get everything nicely in a box e.g. add 24V supply and nicely enclose it
- build a web-access to from outside enable boiler or readout temperature
- experiment further with opentherm commands
* e.g. make sure the thermostat always has the right date/time (via internet time server)
* add external temperature sensor
etc. etc.
If more people have interest, maybe Jiri will develop a shield that fits standard for Wemos ?
Anyhow this is a good product with good support and can be fun and useful to save energy costs!

Unique and Beautiful, and not just for winter
For Arduinoflake
Years ago I wrote a screensaver which generated snowflakes. It required a computer and monitor and changing the program to create different patterns required a lot of work....
Arduinoflake is really amazing. The integration of circuit board and display is wonderful. The touch interface makes is easy to select one of the stock algorithms, and the ISP makes it straightforward to add your own algorithms. There are two options for battery power.
The only thing I added was a way to hang it (a little hot glue and a cord).
As with most SMD, the soldering was a little finicky, but practice makes practiced. The PCB masking and some flux made assembly quick.
I recommend this as a great design and as a nice gift.
