Set Reaction > Script Action

[gwp1]

So I searched this forum earlier but didn't find this thread. A generic global Internet search netted me this old nugget of info on exactly the first issue, the MSR>HA connectivity.

Using @toggledbits one-liner

    curl -o - 'http://192.168.0.15:8123/api/config'

returned just what I needed to determine it was an IP configuration error. I'd taken painstaking efforts to re-IP the new HA to the old HA's original IP... and then (for some inexplicable reason) updated the reactor.yaml with the new long-lived access token AND the temporary IP. Dunno what I was thinking... or if I was thinking... in that moment. But that's fixed now and MSR and HA are happily chatting away.

So now I have the two issues remaining:

My first issue: I'm logged into the msr CT as reactor (I used the suggested username just to keep things simple as this is new space for me and I was high off my success of migrating HA over).

When I run

docker pull toggledbits/reactor:latest-amd64
... it assigns the \reactor\ subdirectory where installed root ownership. I am absolutely logged in with the correct non-root user.

Second issue: I copied over the following folders:

When MSR loads, all of my Global Expressions are missing.

That would be correct. Reactor runs as root inside its docker container (very common with docker).

Always look at the logs. Something is probably in there. Your screen shot doesn't show permissions, but that's likely the issue. Reactor runs as root in the container, and will have rootish behavior in the config, logs, storage, etc.

VMs often have virtual network switches/routers and virtual firewalls. That could be the issue. It could also be that filtering/firewall on the HA side doesn't like the IP address the Reactor VM is coming from. That seems more likely as other controller endpoints are connectable.

@toggledbits very helpful on the docker explanation - this is my very first foray into docker (using it with MSR) so it's all fresh and new to me. Thank you.

I resolved the HA <-> MSR issue - it was a bad IP in the reactor.yaml file.

What file do Global Expressions live in? They are literally gone from the UI.

And I have LOTS of them in production.

The log shows this, which is not surprising given none of them are there:

[latest-24366]2025-01-12T16:58:29.554Z <Rule:ERR> Predicate#rule-m34m60yh/trig condition refers to undefined global `ambient_windspeed'

Look at the startup messages. Reactor loads the global expressions at startup. That's where the useful messages will be.

They live in storage/expressions.json, but recent similar experience suggests that if one file has broken permissions, many do, so whatever you learn from that one file will likely need to be applied to many. Log in to your virtual machine, do ls -la from inside the storage subdirectory, and post the entire output. Also fetch http://reactor-ip-address:port/api/v1/system and post that output.

By the way, it's also plausible that you haven't mapped your docker container to the right directory. Can you describe how you are launching the docker container, and post any commands you may have executed doing that?

@toggledbits the link to @cw-kid's issue was the key: what he saw was exactly what I saw. 1kb file size, all of it.

I did copy the entire storage folder (along with the rest) vs cherry-picking but somehow the file size thing he saw was replicated here. I recopied but checked <user> <group> the expressions.json file (after confirming both file size and contents) and started the new MSR and it's all there. I even did a test Rule Set > Rule create/del and all is well.

I've shut down the RPi legacy system for now... gonna test run the new one.

QQ... at the bottom of the rules now I see a history that I don't recall seeing in my legacy system (which is bare metal and current). I went back and it's in the legacy system - very nice. Shamefully going to ask when that was added.

Check the release notes.

Make sure you restart Reactor after doing a create, and make sure the rule still exists, and then delete it, restart, and make sure it stays gone after the restart. If not, your storage permissions don't have sufficient write privileges. The reason for this particular sequence is that Reactor caches writes to reduce load on flash memories (like the MicroSD cards typical of Pi's), so it may be several minutes before stuff in memory is written to disk. Restarting Reactor forces the write during shudown.

@toggledbits Fair enough

[toggledbits]

Also see the edit I just made regarding your test. Apologies for brevity. I'm on the run today.

[gwp1]

@toggledbits AH - will do that post-haste. Thanks. And fully appreciate the "on the run".

[gwp1]

@toggledbits Confirmed. Added test Ruleset and Rule. Tools>Restart, they stuck. Deleted test Rule and Ruleset, Tools>Restart, they were still gone.

Next up: docker-compose

To bring this all full circle, I had installed Portainer just to see what it was/did. Rereading the manual for MSR I stumbled across Portainer-specific instructions.

Short story long, I deleted the original container and created a new one thru the Portainer path. Done in mere minutes, runs flawlessly and I don't need to worry about the docker-compose errors I was getting.

Going to mark this topic as solved as all of the three issues were addressed.
