@DevDavid thanks very much for running this by the community. and thanks for sticking your head above the parapet to engage with users; I think some of the commentary here is a bit unfairly-directed, so try not to take it to heart.
Nightlies sounds like a good idea. It would be a great way to reduce the blast radius of big changes such as those that came in with the introduction of premium – there were unintended gaps in that release, like free-tier functionality’s becoming inaccessible.
So I think the motivation for users to use this isn’t just “try new functionality early whilst it’s being developed and tested”, it’s “some users should be daily-driving the nightlies, so that if there’s a break it can be reported before it gets mainlined”.
As for “would I use it”: I’m generally happy to daily-drive bleeding-edge software and navigate around bugs, but it depends on how much install friction there is (I’m on iOS btw), like does this mean I have to login more often or do I have to re-pair my inverter every time it updates.
“Would I benefit from the functionality”: I think I wouldn’t. I don’t think GivEnergy’s roadmap is at all aligned with the functionality I want.
For me I have one primary ask, and that’s reliability.
The Modbus / GivTCP connection is incredibly unreliable, like unbelievably, unusably unreliable. It is the most normal thing in the world for me to check my GivTCP dashboard and see it hasn’t been able to connect to the inverter or scrape the registers in days. My inverter is connected over Ethernet, I don’t know of any other clients (unless the cloud connection counts as a client) competing for use of the modbus. This can be resolved temporarily by rebooting the inverter, but it breaks again within a day. It’s no stretch to say I don’t have local control of my inverter.
The GivEnergy app is extremely unreliable. Almost every time I apply inverter settings, it says that it failed. And sometimes that’s not true, it succeeded.
The GivEnergy Cloud SaaS is extremely unreliable. Just like in the app: almost every time I apply inverter settings, it says that it failed. And likewise, sometimes that’s not true, it succeeded.
This has downstream repercussions for Axle’s automation also. Almost every time there’s a grid event: they either fail to enable my automation, or fail to restore it afterwards. I find on most grid events that my inverter either exported nothing, or that I’m importing grid power during peak hours afterwards.
There’s a chance this is just a problem on their end, but my own experiences seeing so many of my actions in the GivEnergy Cloud SaaS fail, do not fill me with confidence.
There are so many things I’d like to automate with my GivEnergy Gen3 Hybrid Inverter 8kW and my 4x Stackable Battery 1-phase. But everything I try fails, and now I have pared back my ambitions to just the most boring charge schedule because I don’t trust the inverter firmware, the modbus, the app, the SaaS, or Axle’s automation.
I have feature requests for how I would want battery automation to work, and how to make it better serve Axle grid events, but I think none of that matters until automation reliability can be fixed.
So I would say: yes do nightlies. Even if there’s not many users, you only need a couple to get early warning that a release has a break in it. But I worry that the roadmap is “more features” or “more reasons to buy premium” when I would say all feature-development is moot until local control and configuration of inverter can be made to work reliably.
