- Keep alive a single TCP connection for each hub instead of constantly opening a new one for each request
- Add a heartbeat sensor that pings the hub periodically to check it's alive
Instead of creating a new connection for each HTTP request, keep a long lived TCP connection alive and use it for all requests. This should use fewer resources on the hub and hopefully avoid stability problems that can occur when the hub has been up for many months.
Periodically ping the hub to check it's still responding. This should help keep the hub's network interface awake.
Elsewhere it's assumed that unavailable values are either not set in state dictionary or are None. Where empty strings are used it's logging some warnings about float conversions which aren't needed.
