2022-02-08 Upgrading the fiber to the shed network
The current fiber to the shed network is working fine but only gives the Raspberry Pi based NTP server network at a speed of 100 mbit. The link is working fine but the next device with network problems due to unreliable wifi is showing up: the solarpanel inverter in the shed is sometimes unreachable for my solar inverter monitoring using modbus/tcp and that means I 'miss' measurements. The propetairy monitoring that solaredge does can deal with interruptions in reachability and upload older data, but the modbus/tcp monitoring I use can only access real-time data. My first plan was to look at industrial switches because of the extended temperature and humidity ranges in the shed. But having both 'industrial' and 'sfp slot' costs a lot of money. My next thought is to put all the possibly sensitive electronics in one case and hope the temperature and humidity inside that case stay within a reasonable range. This thought is based on the fact that the Raspberry Pi based NTP server functions fine in a not very closed wooden box without being affected by temperature or humidity.
