Yeah, by the time I had written the post, the proceeding thread had disappeared leaving it making no sense, I was out of time and had to go out so I just deleted it until things settled.
No not at all, I would have edited it to make sense, but if I do that now it will leave these posts hanging so I will just copy the content here so it is searchable text not an image (also so I can edit my typo on the version I was running for some months, v3.1.4 not v3.1.6, that is what I have now upgraded to).
So what I posted was…
Regards the redis extension, we have discussed that in some depth elsewhere, but using the install guide will fetch the latest version, only the emonSD image needs further discussion as there are 3 install methods used on that image and it has historically been fixed at v2.2.8.
I have been using redis v3.1.4 for several months without an issue and now upgraded to 3.1.6 without any obvious issues yet, however I am using php7 on Stretch not am emonSD image so it needs testing for php5.
As for the dio module… Why is it still in the guide??? I have brought this up before, more than once. We have not used the dio module since the emoncms “rfm2pi” module and the php script for the rfm2pi, before oemgateway and emonhub, it maybe 4 years since it has been used and as the serial port is used exclusively by emonhub (when installed) installing the dio module only adds the possibility of a user running a non-standard php script that interferes with the serial port and emonhub. I stopped including it in any of my SD card images or personal install scripts/guides way before the emonpi was launched.
