Android users of LONDINIUM app

by Reiss Gunson on Monday, 01 March 2021 13:06

a number of android users have made me aware of connection issues with v1.0.4 of the londinium app

blynk have just replied to me to advise the following;

Is v1.0.4 the ‘new’ version?
Yes, that was the new version. 
We added a small change and published a new version: 1.0.5
The issue with adding/connecting devices should be fixed in it.


so please delete v1.0.4 if you are using the android version of the app and download v1.0.5 and let me know if issues remain

no iOS user has reported any issue with v1.2 from the app store

kind regards



LONDINIUM app v1.2 is now available in the App store

I am unsure if the updated Android version is available yet

KInd regards


LONDINIUM app outage issue: explanation

by Reiss Gunson on Saturday, 27 February 2021 18:52

Blynk have helpfully provided a detailed explanation of why the expiry of an SSL certificate was responsible for the outage, and why only a subset of users were affected:


The certificate was updated automatically 2 days ago. Old Blynk firmware had a bug where the intermediate certificate footprint was hardcoded. The new certificate has the intermediate certificate changed. That caused connection issues for the hardware. 
Why not all users where affected?
Some of the devices established the connection before the certificate was updated, so they were able to connect. The connection is keep-alive and everything was ok. Also, during the certificate update the server is not restarted, so connections with prev certificate were working fine. Only new connections weren't working. That's why we weren't able to detect this issue by our monitoring system.
The fix is the next - right now we serve 2 certificates. One is for hardware, another is for web and apps.
That should solve the issue. Sorry for inconveniences.


Blynk have definitely exceeded my expectations in their response to this issue.  I am very impressed as we pushed the boat out developing the R24 with this industry leading technology and they have proven themselves to be a very good business partner.

KInd regards

LONDINIUM app update

by Reiss Gunson on Saturday, 27 February 2021 10:57

this email just landed (21:40 UTC 26FEB2021):



please refer to the attached screenshot that shows i configured the parameters you specified in the manner you requested
Everything is configured correctly. Thank You!
does this now have to be reviewed by Apple before they will let it into the App store?
if so im assuming several days?
Yes. The new version of your application should be reviewed. It will take a couple of days.

while i think of it, what is the situation for the Android platform?
The new version is already under review. Should be updated tomorrow. 
Please let me know if you have any comments or questions.



I have also asked for an explanation of the cause as the vast majority of users have been unaffected.  If this is provided i will let you know

Please note that you can continue to make espresso with your machine, you simply dont try to connect to the app (log out of the app and close the app).  You will lose the smart timer function and the ability to remotely change the preinfusion pressure, but you can change the preinfusion pressure direcly on the console of the machine if you remove the right side panel

Kind regards



Londinium app update

by Reiss Gunson on Saturday, 27 February 2021 09:47

Blynk have responded very quickly and had a fix developed within an hour of the right person getting involved

Unfortunately in this instance the time zones worked against us as Blynk are in New York and I am in New Zealand, but here we are

Blynk have now asked me to enter the privacy and data control settings for the new version of the app, which i have just completed

My expectation is Blynk will then release the App to Apple for publication and then we wait - i have no idea whether that process is 'semi-instantanuous' or whether some days may pass whiist the wheels of the corporate juggernaut turn

As i understand it you will need to download a new version of the App from the App store; the current version will not work

I will post here again as soon as i know more

Thank you for your understanding

Blynk app service issue

I am aware that about two dozen users of LR/R24 are unable to connect to the app presently

I am in the process of making contact with Blynk to discover what the issue is

I will post again here when i have something to say

I apologise to those users affected for the inconvenience

It might take a bit longer as this is the first time we have expereinced an outage

Kind regards

A Nautilus grinder is on its way from Germany

by Reiss Gunson on Wednesday, 03 February 2021 12:18

we start the year by adding another good espresso grinder to sit beside the Kafatek Max II with Shuriken Sweet burrs, the Nautilus by Titus Grinding of Germany

i like to support independant operators that have invested a lot to help us create consistently excellent espresso; all of the operators in this space live and breathe their craft; it isnt a 9-5 job, they all wake up in the middle of the night wondering about a particualr issue, or suddenly realising the answer to a particular problem that they have been mulling over for months

please note that we paid the market rates for both of these grinders

while it is true that we are playing in the realm of diminishing returns with grinders at this level, that is only true if you are drinking dark roasts.  if you drink dark roasts dont waste your money on any of these grinders, get a Niche Zero and youll have everything you ever need.  dark roasts are so soft you can crush them between your forefinger and thumb.

however, these grinders are an absolute necessity if you want to make pleasing espresso with light roasts, the lighter the roast the more essential they are.  some light roasts are so hard they will stall all but the most powerful of these grinders; the Ceado E37Z for example will stall on light roasts unless the beans are fed into the grinder one by one, something i do not consider acceptable on any grinder, let alone one at this price point

one thing i can almost guarantee; the espresso produced from the same roast by these two grinders will be significantly different as they both solve the challenges of grinding in very different ways; both will have relative strengths and weaknesses and i look forward to exploring them
