Thanks Colin, tried
npm install node-red-contrib-oled and just gives pages n pages of error, so I wont waste your time and paste it here.Best is as u said find an alternative. the only other I found in the pallette is 'nodered-sh110' but that fail to install in v1.1.1 also.
I roll back to an olde nr version withr node.js v8.11.1 as suggested by Steve, n it install n works. Obviously not a long term solution, I am surprised that there are no working nodes for oled i2c display as it is such a great display compared to lcd.
Another alternative I guess is to use mqtt and interface to a esp8266 with espeasy oled interface, however just seems a roundabout way.
On the subject of node,js versions and NR versions and NR installation:
1.Is there a reference table somewhere correlating NR versions and node.js versions when u install using the script.
2. Is it possible to modify the script to somehow let user to select which version of NR to install?
3. A script to completely remove NR might be useful. (so one can start from clean slate, I had a look thru the forum,and to complete remove NR is more to it as there are a lot of breadcurumbs)
Anyway back to topic, if anyone has a working oled i2c setup with nr v1.1.1 n node.js v12.13.1, advise will be appreciated.
