interesting - when i found field 130.2 i started comparing it with "Inverter Avg AC Power(kW)" and found it to be identical. your response got me curious, so i asked the old sunpower interface to also plot Inverter Max AC Power and... the two datapoints appear to be identical, going back as far as i can see. do these differ in your account?
i agree, same here, i own this equipment and i just want access to the data. my guess is that they have no way to upgrade the firmware in these inverters/monitors remotely and so i think what we've got is the way it's going to be. even if they could upgrade the firmware, with so many systems in the field i think it could be disastrous for them if they had a bad load. if they change anything they'd probably have to keep it all backward compatible. plus, they'd have to work with SMA on this so all in all it seems like a big hassle on their end to change anything.
actually, now i wonder if this is simply a hash/digest of the preceding messages... because 102 seems to accompany all outputs from the inverter. i have not looked at the responses from the monitoring server but i wonder if it sends back that hash to verify that it's received the monitoring data. that would be one way for the inverter to know if it needs to replay data.
i was watching this pretty carefully yesterday and it seems like as long as any sunlight is hitting the panels, you get data every 5 minutes. so that's good. i was worried about having to make the script stateful in case the interval changed. however, it turns out the script does have to be stateful because PVOutputs is expecting daily cumulative energy production in each update, rather than interval energy production. this kind of sucks as now i need to track and reset the daily cumulative at local midnight (or some other safe time.)
i was concerned about this because a big burst could violate the pvoutput rate limit rules, and so i might have to handle this by aggregating some production data before posting it. i suppose one solution to that problem is just to donate to PVoutputs
